The heart of the build is the HDZero AIO5, the first single-board 5-in-1 AIO: flight controller, 4-in-1 ESC, HDZero VTX, SPI ELRS 2.4GHz receiver, and BEC on one thick PCB. Replacing the usual two-board stack improves durability and simplicity, and the lightweight HDZero Eco camera feeds HD composite video over a single wire rather than a fragile MIPI ribbon cable. The result is the first HD brushless whoop under 19.4g — 19.3g bare. That low mass is the point: it bounces off walls and furniture instead of breaking parts, making it ideal for indoor reflex and race training. It is an indoor and calm-air machine, not an outdoor quad — as a 65mm 1S whoop it is easily blown around by any wind — and flight time is short, officially around 2.5-3 minutes on the recommended 1S 300mAh pack. Video is native HDZero 720p60 in 4:3 with near-zero fixed latency, pairing directly with HDZero goggles such as the BoxPro+; the AIO5 keeps transmitting down to 2.5V so video never cuts before the motors quit, and the VTX switches between 25mW and 200mW with a u.FL antenna connector. The Eco is the budget camera of the pair — 1/3-inch sensor, 4:3 only, no WDR — visibly weaker in image and low light than the Lux on the 0.6g-heavier Mobula6 Freestyle HD. It arrives true BNF: the built-in SPI ELRS 2.4GHz receiver (ExpressLRS v3.0, 25-500Hz packet rates) binds to any ELRS 2.4GHz radio out of the box, with Betaflight 4.4.2, Bluejay ESC firmware, and onboard blackbox from the factory. Mobula6-platform spares — canopies, frames, SE0702 motors, 31mm props — are widely stocked; a spare canopy and props ship in the box, and the AIO5 replacement board is sold separately. - 65mm · 1S · 19.3g bare · Ducted (visually verified) - HDZero Eco — 1/3in sensor, 720p60 4:3, FOV D150/H120/V98, single-wire HD composite output camera · HDZero AIO5 (integrated 5.8GHz HDZero VTX on 5-in-1 AIO board, u.FL antenna) · SPI ELRS 2.4GHz (built-in, ExpressLRS v3.0-compatible, 25-500Hz packet rates) - Motors SE0702 28000KV (1.5g, 1mm shaft) · 31mm props - Battery: 1S 300mAh (A30 or BT2.0 plug) (A30 (official spec also accepts BT2.0-plug packs)) - VelociDrone: Mobula 6 / Mobula 6 2024 (Micro pack) Vendors: - [HDZero.us](https://hdzero.us/products/happymodel-mobula6-race-hd) — Default Title: $225.99 in stock (checked 2026-07-04) - [RaceDayQuads](https://www.racedayquads.com/products/pre-order-happymodel-mobula6-whoop-hd-w-hdzero-eco-elrs-2-4ghz-racing) — Default Title: $227.99 in stock (checked 2026-07-04) - [Rotorama (EU)](https://www.rotorama.com/product/happymodel-mobula6-race-hd) — 1S ELRS: €214.79 in stock (checked 2026-07-02) - [HDZero.com](https://www.hd-zero.com/product-page/happymodel-mobula6-race-hd) — Default Title: $189.99 sold out (checked 2026-07-04) - [GetFPV](https://www.getfpv.com/happymodel-mobula6-whoop-hd-w-hdzero-eco-elrs-2-4ghz-racing.html) — Default Title: $246.99 in stock (checked 2026-07-04) - [Pyrodrone](https://pyrodrone.com/products/happymodel-mobula6-race-hd-1s-hdzero-aio5-elrs-2-4ghz-ultra-light-micro-fpv-whoop-bnf) — Default Title: $235.99 in stock (checked 2026-07-04) ### Happymodel Mobula6 Freestyle HD The Happymodel Mobula6 Freestyle HD is a 65mm 1S brushless tiny whoop — the first sub-20g digital HD whoop — built for indoor and calm-weather freestyle with true HDZero 720p60 video. It's the natural pick for HDZero goggle owners wanting HD in the smallest weight class. The heart of the build is the HDZero AIO5, the first single-board whoop flight controller to integrate an HDZero digital VTX, SPI ELRS 2.4GHz receiver, 4-in-1 ESC, and 5V BEC. It pairs with the RunCam HDZero Lux camera on a fixed 25-degree mount, sending 720p HD over a single composite wire instead of a fragile MIPI ribbon cable — a durability win in a crash-prone class, alongside the elimination of the two-board stack. The Lux is the image-quality pick of the AIO5 camera pair: a 1/2-inch sensor with WDR, 1080p-to-720p oversampling, strong low-light performance, and a large 94-degree vertical FOV in 4:3 at 720p60. Native HDZero video is near-zero latency and plug-and-play with HDZero BoxPro+ goggles — no module or adapter needed — with VTX output selectable between 25mW and 200mW. The VTX keeps transmitting down to 2.5V, so video holds on until the motors quit at the end of a pack. At 19.6g bare it was the first sub-20g digital HD whoop — far lighter than earlier ~25g HDZero whoop conversions, so it flies much closer to an analog-weight 65mm quad. It's built for indoor and calm-weather proximity and freestyle: wind pushes a 65mm 1S whoop around, and Happymodel's own flight-time figure is around 3 minutes on the recommended 1S 300mAh, since the HD VTX draws more power than an analog setup in this class. It ships flight-ready — Bluejay ESC firmware preinstalled, a Betaflight 4.4.2 factory tune with a published dump file for easy restore, and a spare canopy and props in the box. Within the lineup, the sibling Race HD swaps in the lighter, cheaper Eco camera on a 20-degree mount; the Freestyle HD's Lux is the stronger low-light camera of the two. - 65mm · 1S · 19.6g bare · Ducted (visually verified) - RunCam HDZero Lux (1/2" CMOS, 720p60 4:3/16:9, WDR, fixed 25° mount) camera · HDZero AIO5 (integrated 5.8GHz HDZero VTX, UFL antenna) · SPI ELRS 2.4GHz (built-in, ExpressLRS v3.0) - Motors 0702 28000KV (7x2mm stator, 1.5g each) · 31mm props - Battery: 1S 300mAh (A30 or BT2.0 plug) (A30 (accepts A30 or BT2.0 packs)) - VelociDrone: Mobula 6 / Mobula 6 2024 (Micro pack) Vendors: - [HDZero.us](https://hdzero.us/products/happymodel-mobula6-freestyle-hd) — Default Title: $235.99 in stock (checked 2026-07-04) - [Pyrodrone](https://pyrodrone.com/products/happymodel-mobula6-freestyle-hd-1s-hdzero-aio5-elrs-2-4ghz-65mm-ultra-light-micro-fpv-whoop-bnf) — Default Title: $245.99 in stock (checked 2026-07-04) - [HDZero.com](https://www.hd-zero.com/product-page/happymodel-mobula6-freestyle-hd) — Default Title: $199.99 sold out (checked 2026-07-04) ### Happymodel Mobula6 ELRS 2024 (HDZero Eco) The Mobula6 ECO 2024 is a 65mm 1S brushless tiny whoop — the first BNF built around HDZero's low-cost ECO camera/VTX bundle — putting 720p60 digital video on a 23.2g bare airframe. It's an indoor proximity trainer for pilots flying ELRS radios and HDZero goggles. The ECO bundle replaces the fragile MIPI ribbon with a plain HD composite wire harness, so the camera-to-VTX link is more crash-durable and easy to re-solder or extend. The receiver is a true UART ELRS 2.4GHz V3.0.1 unit — not SPI — with WiFi and passthrough firmware updates, giving full ExpressLRS ecosystem compatibility and none of the SPI firmware limitations. It's primarily an indoor proximity machine: the ECO cam's huge 98-degree vertical FOV is made for ripping tight spaces, and it flies noticeably more agile than the previous Mobula6 HDZero. The stock tune handles wind well enough for calm outdoor cruising, though the VTX tops out at 200mW (25/200mW only), which caps outdoor range. Plug-in motor connectors allow solder-free motor swaps. Video is 720p60 progressive-scan with stable color and none of analog's brightness flicker or static, displaying natively on HDZero goggles including the BoxPro line. The ECO camera itself is a clear step down from MIPI-based HDZero cams like the Nano V3 — a low-cost, analog-grade sensor that benefits from manual settings tweaks (brightness ~45, sharpness ~15) out of the box. At 23.16g bare it carries a full HDZero digital feed only about 5g over the analog Mobula6 2024, though the ~6.3g digital stack costs some flight time and float versus the 17.8g analog sibling on the same 1S packs. It slots in as an indoor trainer with longer flight time than the Race HD. - 65mm · 1S · 23.16g bare · Ducted (visually verified) - HDZero ECO Camera (720p@60fps 4:3, 98° vertical FOV, HD composite output) camera · HDZero ECO VTX (separate cam/VTX stack, HD composite input) · UART/serial ELRS 2.4GHz (ExpressLRS V3.0.1, WiFi/passthrough updatable) - Motors SE0702 KV28000 · 31mm props - Battery: 1S LiPo/LiHV, A30 plug (battery not included) (A30) - VelociDrone: Mobula 6 2024 (Micro pack) Vendors: - [RaceDayQuads](https://www.racedayquads.com/products/happymodel-bnf-mobula6-elrs-2024-ultra-light-65mm-brushless-hdzero-eco-whoop-elrs-2-4ghz) — Default Title: $179.99 sold out (checked 2026-07-04) ### Happymodel Mobula6 HDZero (V3) The original HDZero digital tiny whoop: a 65mm 1S brushless HD craft on the two-board Whoop Lite VTX and Nano Lite camera stack, aimed at HDZero goggle owners who want an indoor cruiser with native 720p60 digital video. Debuting in 2022 as the smallest digital-FPV whoop of its time, the Mobula6 HDZero uses the two-board HDZero Whoop Lite VTX and Nano Lite camera stack. The V3 revision (September 2023) swaps the earlier SPI receiver for a true UART ELRS receiver running ExpressLRS v3.0.1 on the SuperX HD flight controller, and moves from a PH2.0 to a GNB A30 battery connector at 25.7g bare. As a 65mm 1S craft it is a native-digital indoor cruiser: 720p60 HDZero video for BoxPro+ goggles with direct ELRS v3 binding to any ELRS 2.4GHz radio. It is the heaviest of the Mobula6 HD family, and the reviewed platform feels underpowered outdoors, handles wind poorly, and tends to wiggle on dive recovery. Flight time is short — about 2 min 45 s measured on a 1S 300mAh with the lighter 2022 original, the V3 roughly 2g heavier. The V3 flight controller adds onboard blackbox and ships bind-and-fly on Betaflight 4.4.2 with a spare canopy, props, and tools. The A30 connector also accepts BT2.0-plug packs, and Mobula6 platform spares — frames, canopies, EX0802 motors, Gemfan 31mm props — are cheap and widely stocked. Replacement digital-stack parts are thinner, though: the Whoop Lite VTX has been superseded by the Whoop V2 VTX. - 65mm · 1S · 25.7g bare · Ducted (visually verified) - HDZero Nano Lite (1.5g, 0.5in ultra-high-sensitivity CMOS, FOV 4:3 D130/H108/V84, MIPI ribbon to VTX) camera · HDZero Whoop Lite VTX (digital HD 720p60, SmartAudio, 25.5x25.5mm mount) · UART ELRS 2.4GHz, ExpressLRS v3.0.1 factory-installed (SuperX HD ELRS FC, target CRAZYBEEF4DX); earlier revisions were SPI ELRS with ELRS v2-only binding - Motors EX0802 19000KV Unibell brushless (9N12P, 1.7g each) · 31mm props - Battery: 1S LiPo/LiHV, A30 or BT2.0 plug, not included (1S 300mAh is the size Happymodel recommended for earlier revisions and reviewers used) (GNB A30 (BT2.0-plug packs also compatible); earlier SPI revisions used PH2.0) - VelociDrone: Mobula 6 (Micro pack) Vendors: - [rcdrone.top (Happymodel official)](https://www.rcdrone.top/products/happymodel-mobula6-hdzero) — Elrs 2.4G: $258.68 in stock (checked 2026-07-04) ### Happymodel Mobula7 Freestyle HD A 75mm 1S brushless whoop with native HDZero 720p60 video and built-in ELRS — the larger, punchier sibling of the Mobula6 Freestyle HD, for pilots bridging large-space indoor flying to calm-air backyard freestyle at just 24.5g bare. Everything lives on the HDZero AIO5 single-board flight controller: F411 FC, 5A Bluejay ESC, HDZero VTX, SPI ELRS 2.4GHz receiver, and a 5V/1A BEC on one thick PCB. That layout eliminates stack ribbon cables and connector failure points, improving the electronics' crash durability. Up front is the HDZero Lux camera — a 1/2" sensor, 720p60, with HDZero's fixed near-zero latency. This is the larger, punchier sibling of the Mobula6 Freestyle HD. RS0802 25,000KV motors on 40mm HQProp tri-blades give the 1S power system enough authority for calm-air outdoor freestyle, while 24.5g bare — among the lightest 75mm HD digital whoops made — keeps it manageable for large-space indoor flying and light wind. Expect consistent 4-5 minute flights on 1S 450-550mAh packs, per both the manufacturer's figure and reviewer reports. Native HDZero video pairs directly with HDZero BoxPro+ goggles — no adapters or channel workarounds — and the built-in ELRS 2.4GHz receiver binds to any ELRS 2.4GHz radio with no extra hardware, at packet rates up to 500Hz. The receiver is SPI ELRS rather than UART: you bind via bind button or Betaflight (there is no bind-phrase workflow), and receiver features track Betaflight releases. It ships with a spare canopy and props, and Happymodel publishes official Betaflight 4.4.2 and 4.5.1 dump files plus a 3D-printable antenna holder. The all-in-one layout cuts both ways for repair: the ELRS antenna is a fine enamel wire soldered to tiny pads, and a dead ESC channel, VTX, or receiver means replacing the entire AIO5 board. The Lux camera is also crash-fragile, with the IR filter and lens the usual casualties. - 75mm · 1S · 24.5g bare · Ducted (visually verified) - HDZero Lux (1/2" sensor, 720p60, 4:3 and 16:9) camera · HDZero AIO5 (integrated 5.8GHz HDZero VTX) · SPI ELRS 2.4GHz (built-in on AIO5, ExpressLRS v3.0-compatible) - Motors RS0802 KV25000 (1.5mm shaft, unibell) · 40mm props - Battery: 1S 450/550/650mAh (A30 (some retailers list BT2.0; Makerfire lists "A30 or BT2.0 interface")) - VelociDrone: None exact; closest BetaFPV 75x (Micro pack) Vendors: - [Pyrodrone](https://pyrodrone.com/products/happymodel-mobula7-1s-75mm-hdzero-aio5-fc-brushless-whoop-drone-bnf) — Default Title: $271.99 in stock (checked 2026-07-04) - [rcdrone.top (Happymodel official)](https://rcdrone.top/products/happymodel-mobula7-freestyle-hd-75mm-1s-1-6-inch-tinywhoop-fpv-drone) — Default Title: $299.00 in stock (checked 2026-07-04) - [Rotorama (EU)](https://www.rotorama.com/product/happymodel-mobula-7-freestyle-hdzero-1s-elrs) — 1S ELRS: €227.19 in stock (checked 2026-07-02) - [RaceDayQuads](https://www.racedayquads.com/products/happymodel-mobula7-whoop-hd-w-hdzero-lux-elrs-2-4ghz-freestyle) — Default Title: $239.99 sold out (checked 2026-07-04) ### Happymodel Moblite7 HDZero (V3) Happymodel's Moblite7 HDZero V3 is an ultralight 75mm 1S brushless whoop with native HDZero digital video, weighing 31.5 g without battery. It's an efficient cruiser for parks and larger indoor spaces — the featherweight of the 75mm digital-whoop class. The V3 revision replaced the earlier SPI-ELRS Crazybee board with a SuperX HD AIO carrying a UART ExpressLRS 2.4GHz v3 receiver, 12A-per-motor BLHeli_S ESCs (15A burst) running Bluejay firmware from the factory — up from 5A on earlier revisions — and EX1002 20000KV motors, among the larger motors fitted in the 75mm whoop category. The VTX is switchable between 25mW and 200mW with SmartAudio; 200 mW is strong output for a whoop-class digital VTX. Video is native HDZero — a Whoop Lite VTX paired with a Nano Lite camera — plug-and-play with HDZero goggles such as the BoxPro+, no adapter or second video system needed. The UART receiver ships on ELRS v3.0.1 and binds and updates like a standalone ELRS RX with an ELRS 3.x radio, sidestepping the version-lock and binding headaches of older SPI-ELRS boards. The box includes an extra canopy, propeller set, screw set, and HDZero cable. At 31.5 g without battery per the manufacturer's V3 page, it sits at the featherweight end of the 75mm digital-whoop class — an efficient cruiser for parks and larger indoor spaces rather than a power machine. Owner reports describe a stock setup that doesn't grip well in turns and a sensitive throttle response, making it better suited to open outdoor courses than tight indoor lines. - 75mm · 1S · 31.5g bare · Ducted (visually verified) - HDZero Nano Lite (CMOS, 130° diagonal FOV, 1.5 g) camera · HDZero Whoop Lite VTX, 25/200mW switchable, SmartAudio, 4.5 g · UART ExpressLRS 2.4GHz, factory firmware ELRS v3.0.1 (CRSF) - Motors Happymodel EX1002 20000KV (9N12P, 10x2mm stator) · 40mm props - Battery: 1S 450–550mAh LiPo/LiHV with A30 connector (not included; Happymodel recommends packs with lead wire) (GNB A30) - VelociDrone: None exact; closest BetaFPV 75x (Micro pack) Vendors: - [RaceDayQuads](https://www.racedayquads.com/products/happymodel-bnf-moblite7-hdzero-1s-75mm-whoop-choose-your-rx) — ELRS SPI: $251.99 sold out (checked 2026-07-04) - [GetFPV](https://www.getfpv.com/happymodel-moblite7-v3-1s-75mm-whoop-w-hdzero-uart-elrs-2-4ghz.html) — Default Title: $272.99 sold out (checked 2026-07-04) ### Happymodel M8 Freestyle HD (Mobula8) An 80mm 2S bind-and-fly super-whoop built for outdoor freestyle, aimed at pilots stepping up from 1S trainers. At under 33.5g bare it is one of the lightest 2S digital freestyle whoops, with native HDZero video onboard. Everything rides on the HDZero AIO15 5-in-1 board — flight controller, genuine HDZero VTX, serial ELRS receiver, and 15A ESC on a single board — with an HDZero Lux 720p60 camera up front. RS1102 13500KV motors spin 45mm tri-blade props on the 80mm frame. The positioning is squarely outdoor freestyle: the step up from 1S trainers like the M6 and M7 Freestyle. Retailers explicitly call it an outdoor aircraft, not an indoor reflex trainer. Its slot in the lineup is outdoor 2S — wind-tolerant while still whoop-light. As a native HDZero quad it pairs directly with HDZero BoxPro+ goggles, and its true UART ELRS receiver keeps it fully update-compatible with any ELRS 2.4GHz radio, so it takes normal ExpressLRS firmware updates rather than lagging the way SPI-ELRS whoops can. - 80mm · 2S · 33.5g bare · Ducted (visually verified) - HDZero Lux (1/2-inch sensor, 720p60, 155-deg diagonal FOV, WDR) camera · HDZero AIO15 (integrated 5-in-1: FC + HDZero VTX + ELRS RX + 15A 4-in-1 ESC) · UART/serial ELRS 2.4GHz (built-in, pre-soldered 31mm wire antenna) - Motors RS1102 KV13500 (11x2mm stator, 2.8g each) · 45mm props - Battery: 2S 550mAh LiPo (XT30, not included) (XT30) - VelociDrone: None exact; closest BetaFPV 75x (Micro pack) Vendors: - [HDZero.us](https://hdzero.us/products/hdzero-m8-freestyle-hd-bnf) — Default Title: $249.99 in stock (checked 2026-07-04) - [Pyrodrone](https://pyrodrone.com/products/happymodel-m8-freestyle-hdzero-80mm-digital-hd-micro-fpv-whoop-elrs-2-4) — Default Title: $272.99 in stock (checked 2026-07-04) - [RaceDayQuads](https://www.racedayquads.com/products/happymodel-mobula8-2s-whoop-hd-w-hdzero-lux-elrs-2-4ghz) — Default Title: $212.49 sold out (checked 2026-07-04) ### Five33 65mm HDZero Race Whoop RTF A hand-built 65mm 1S race whoop from Five33, assembled around HDZero digital video and tuned and test-flown before shipping. At 18.6g bare it sits at the light end of the digital-whoop class, aimed at indoor and whoop-track racing. Five33 builds each unit by hand in Evan Turner's Maryville, Tennessee shop, on a BetaFPV Air65 II frame around the HDZero AIO5 board and HDZero Eco camera, with HQProp 31mm props, 0702 30000KV motors, and BT2.0 batteries. Everything is standard, off-the-shelf hardware, so spares are cheap and easy to source. Orders come with a choice of four camera angles (30/35/37/40 degrees) and a black or white frame — those variants are camera angles, not motor KV. "RTF" here means fully built, race-tuned, and test-flown before shipping — it flies well out of the box without DIY tuning — but no battery, radio, or goggles are included. At 18.6g bare it sits at the light end of the digital-whoop class, with 1S race-class agility and low crash energy, and it's aimed at indoor and whoop-track racing rather than outdoor cruising. Native HDZero video makes it a direct match for HDZero goggles like the BoxPro+: a 720p-class image with the low, fixed latency HDZero is known for, a clear step up from analog whoop video. The Eco is the budget composite-signal camera in the HDZero lineup, so image quality sits below the Lux/nano-class HDZero cameras, and the VTX tops out at 200mW through a linear antenna — fine for indoor racing, with limited range and penetration outdoors. The built-in ELRS 2.4GHz receiver binds to any ELRS 2.4GHz radio (bind phrase or button via Betaflight, on ELRS v3), but it is SPI-based: its firmware is baked into Betaflight, cannot be updated independently, and there is no blackbox on the F411 MCU. With Betaflight and ELRS developers phasing out SPI+F411 targets, long-term firmware headroom depends on HDZero/HappyModel. The AIO5 board does have a community reputation as one of the tougher 5-in-1 AIOs in a crash. - 65mm · 1S · 18.6g bare (~25.6g AUW) · Ducted (visually verified) - HDZero Eco camera · HDZero AIO5 (integrated HDZero VTX, linear antenna) · SPI ELRS 2.4GHz v3.0 (built into HDZero AIO5) - Motors 0702 30000KV · 31mm props - Battery: 1S 300mAh or 350mAh HV (BT2.0) - VelociDrone: Race Whoop (Micro pack), not exact SKU Vendors: - [Five33 (direct)](https://flyfive33.com/products/533-rtf-hdz-race-whoop) — 30 / Black: $254.99 in stock; 30 / White: $254.99 in stock; 35 / Black: $254.99 in stock; 35 / White: $254.99 in stock; 37 / Black: $254.99 in stock; 37 / White: $254.99 in stock; 40 / Black: $254.99 in stock; 40 / White: $254.99 in stock (checked 2026-07-04) ### Five33 UDL Spec Drone RTF (75mm) A hand-built 75mm 1S HDZero race whoop on the Happymodel Mobula7 V4 airframe, purpose-built for Five33's Underground Drone League Igniter spec class — the turnkey way to arrive race-legal with identical, RPM-limited hardware so racing comes down to pilot skill. Each unit is hand-assembled in Five33's Maryville, Tennessee shop on the Happymodel Mobula7 V4 airframe. The electronics live on a single HDZero AIO5 board — flight controller, 4-in-1 ESC, digital VTX, and SPI ELRS receiver on one thick PCB — paired with a RunCam HDZero Eco camera, EX0802 19,000KV motors, and 40mm HQProp props. Five33's in-house build team test-flies every drone before shipping, with a pro-level tune applied. It exists for one job: UDL's 75mm Igniter class, which mandates identical, RPM-limited, LED-equipped builds at a class-minimum 40g all-up weight so racing comes down to pilot skill rather than hardware. That makes it deliberately slower than an open-class 75mm racer by design. The VTX output switches between 25mW and 200mW, and the linear-polarized antenna suits the indoor/track racing the class is built around. Native HDZero video feeds straight into HDZero goggles like the BoxPro+ with no extra receiver module, and the feed keeps transmitting down to 2.5V so video outlasts the motors. The built-in SPI ExpressLRS 2.4GHz receiver binds directly to any ELRS 2.4GHz radio with nothing external to mount. Because every component is an off-the-shelf catalog part Five33 sells individually, crash repairs are cheap and simple, and the single-board layout leaves minimal wiring to break. - 75mm · 1S · 40g bare (~40g AUW) · Ducted (visually verified) - RunCam HDZero Eco camera · HDZero 5.8GHz digital, integrated in AIO5, linear antenna · SPI ExpressLRS 2.4GHz v3.0 (built into HDZero AIO5) - Motors Happymodel EX0802 19,000KV · 40mm props - Battery: 1S 450mAh (not included; Five33 links Tattu 450mAh 1S) (BT2.0 (Five33 pairs it with the Tattu 450mAh 1S BT2.0 pack)) - VelociDrone: None exact; closest BetaFPV 75x (Micro pack) Vendors: - [Five33 (direct)](https://flyfive33.com/products/533-rtf-udl) — Black / Addressable: $251.99 in stock; Black / Set Color - see order notes: $251.99 in stock; White / Addressable: $251.99 in stock; White / Set Color - see order notes: $251.99 in stock (checked 2026-07-04) - [Five33 (Hot & Ready drops)](https://flyfive33.com/products/hot-ready-75mm-udl-whoop) — Default Title: $214.99 sold out (checked 2026-07-04) ### BetaFPV Meteor75 Pro 1S HD (HDZero) A 75mm ducted 1S brushless whoop that pairs BetaFPV's largest 1S frame — 45mm tri-blade props — with genuine HDZero digital video. It suits pilots after relaxed indoor and backyard HD cruising rather than racing. The Meteor75 Pro is a 75mm ducted 1S brushless whoop built on BetaFPV's largest 1S frame of its era, spinning 45mm tri-blade props on 1102 22000KV motors. Video comes from a genuine HDZero Whoop Lite VTX and Nano Lite camera — 720p60 digital video with sub-19ms latency, switchable 25mW/200mW output, natively compatible with HDZero BoxPro+ goggles. At 34.87g bare, the HDZero variant is the lightest configuration, 1.5-5.6g lighter than the Meteor75 HD it replaced. This is a relaxed indoor and backyard HD cruiser rather than a racer: the high-KV motor/prop combo sags 1S packs hard under aggressive throttle, and the digital VTX shuts down below 3.1V, so hard punch-outs on a tired pack can black out video mid-flight. Expect 3-4 minutes of relaxed cruising, with a default tune that gets shaky in even a ~10mph breeze. An adjustable 0-40 degree camera angle covers slow indoor line work and faster outdoor cruising. The radio link is a serial (UART) ELRS 2.4GHz receiver rather than SPI: it binds like any standard ELRS RX and takes full ExpressLRS Configurator firmware updates (V2 stock, upgradeable to V3) without reflashing Betaflight. Motors attach with plug connectors, so swaps need no soldering, and the first-party spares ecosystem is extensive — Meteor75 Pro frames and the Micro Canopy Lite sold separately in seven colors, plus standard Gemfan 45mm props and 1102 motors. - 75mm · 1S · 34.87g bare (~49.2g AUW) · Ducted (visually verified) - HDZero Nano Lite (720p60) camera · HDZero Whoop Lite bundle (separate VTX + dipole antenna) · UART/serial ELRS 2.4GHz (BetaFPV F4 1S 5A AIO, ELRS V2 stock, upgradeable to V3) - Motors 1102 22000KV · 45mm props - Battery: 1S 550mAh LiHV (BT2.0) (BT2.0) - VelociDrone: None exact; closest BetaFPV 75x (Micro pack) - Sold in both HDZero and Walksnail variants; this entry covers the HDZero + ELRS version.

A 2022-era build, it pairs the classic Meteor75 frame and 1102 18000KV motors with the HDZero Whoop Lite VTX and Nano Lite camera, coming in at 36.4g bare — about 4g lighter than the Walksnail edition of the same quad, which keeps it in the flyable indoor 1S weight class. The BT2.0 battery connector reduces connector resistance versus PH2.0 for better voltage sag behavior on 1S. It flies as an indoor/backyard HD trainer, and the factory Betaflight tune on the Meteor75 HD platform is reported as spot-on out of the box, needing no PID changes. HD digital whoops of this generation run 5-8g heavier than analog equivalents, so it carries more momentum and flies less crisply indoors on 1S than an analog Meteor75. Expect about 3.5 minutes on the recommended 450mAh pack. The ELRS variant carries a true serial/UART ELRS 2.4GHz receiver (F4 1S 5A FC Serial ELRS V2.0) that can be updated to ExpressLRS v3 independently, without reflashing Betaflight — so it stays feature-current with any ELRS 2.4GHz radio, unlike SPI ELRS whoops. The native HDZero video system is plug-and-play with HDZero goggles such as the BoxPro+, delivering clear 720p60 digital video that handles dim indoor lighting well. The stock Nano Lite is a 720p60-only budget camera — there is no 540p90 low-latency race mode without a Nano90 camera upgrade, and image quality is a step below HDZero's best cameras. It slots in as the budget digital sibling to the newer Meteor75 Pro HD, which superseded it with a lighter 34.9g HDZero build on a larger, more efficient frame. Spares are easy: the Meteor75 frame, 40mm 3-blade Gemfan props, and 1102 18000KV motors are all standard BetaFPV parts sold separately. - 75mm · 1S · 36.4g bare · Ducted (visually verified) - HDZero Nano Lite camera · HDZero Whoop Lite (Whoop Lite Bundle) · UART/serial ELRS 2.4GHz (F4 1S 5A FC Serial ELRS V2.0; Frsky SPI and TBS variants also sold) - Motors 1102 18000KV · 40mm props - Battery: 1S 450mAh BT2.0 30C (BetaFPV later recommended BT2.0 550mAh for longer flights) (BT2.0) - VelociDrone: None exact; closest BetaFPV 75x (Micro pack) Vendors: - [BetaFPV (direct)](https://betafpv.com/products/meteor75-brushless-whoop-quadcopter-1s-hd-digital-vtx) — HDZero / ELRS 2.4G: $219.99 sold out (checked 2026-07-04) - [GetFPV](https://www.getfpv.com/betafpv-meteor75-1s-brushless-whoop-hd-w-hdzero.html) — unchecked ### EMAX Tinyhawk III Plus HDZero The Tinyhawk III Plus HDZero is EMAX's durable 76mm ducted 1-2S brushless whoop, bringing genuine HDZero digital video to the beginner-oriented Tinyhawk line. It flies as a docile indoor duct trainer on 1S and becomes a noticeably quicker park flyer on 2S. Released in late 2023, it brings the beginner Tinyhawk platform into the HDZero ecosystem with a RunCam HDZero Nano Lite camera and HDZero Whoop Lite VTX — a native 720p low-latency feed that pairs directly with HDZero goggles such as the BoxPro+. Power comes from TH0802 II 15000KV motors on a 6A 4-in-1 ESC rated for 1-2S per the official manual. On the included 1S 650mAh HV pack it flies as a gentle ducted indoor trainer; on 2S it turns into a much punchier park flyer. At 35.5g bare — about 3g more than the analog edition — it is heavy for a 76mm 1S whoop, so indoor handling feels floaty next to sub-20g 65mm HDZero whoops, and it needs 2S to feel lively outdoors. The onboard SPI ELRS 2.4GHz receiver (ELRS V3.0) binds to any ELRS 3.x radio with a bind button, a 'bind_rx' command in Betaflight, or a settable bind phrase via 'set expresslrs_uid'. VTX defaults are race-friendly: it ships at 25mW with a low-power lock that holds output down until armed, and VTX/OSD settings are adjustable from Betaflight Configurator or the stick-commanded OSD menu. It is sold bind-and-fly or as a full RTF kit that bundles Transporter 2 HDZero goggles and an E8 ELRS radio for a complete starting package. The spares ecosystem is deep: the one-piece ducted frame kit, AIO FC/ESC/RX board, Whoop Lite VTX, motors, batteries, and props are all sold individually by EMAX and carried by many retailers, and the BNF box includes a 1S 650mAh HV battery, USB charger, spare props, and a hardware pack. - 76mm · 1S · 35.5g bare · Ducted (visually verified) - RunCam HDZero Nano Lite (720p) camera · HDZero Whoop Lite · SPI ELRS 2.4GHz (built-in on AIO FC; SX1280, ELRS V3.0 protocol) - Motors TH0802 II 15000KV · 40mm props - Battery: 1S 650mAh HV, PH2.0 (EMAX 120C OEM; included in kit versions) (PH2.0) - VelociDrone: Tiny Hawk / Tiny Hawk 2 (Micro pack), not exact III Plus Vendors: - [Pyrodrone](https://pyrodrone.com/products/emax-tinyhawk-3-plus-fpv-racing-drone-bnf-hdzero-elrs) — Default Title: $239.99 in stock (checked 2026-07-04) - [EMAX (direct)](https://emaxmodel.com/products/emax-tinyhawk-iii-plus-fpv-racing-drone-rtf-bnf-with-hd-zero-analog-version-plus-elrs) — TH III Plus RTF HD Zero version: $754.58 in stock; TH III Plus BNF HD Zero version: $369.58 in stock (checked 2026-07-04) - [ProgressiveRC (Seattle)](https://www.progressiverc.com/products/emax-tinyhawk-iii-plus-hd-rtf-indoor-racing-quad) — Default Title: $499.99 sold out (checked 2026-07-04) - [GetFPV](https://www.getfpv.com/emax-tinyhawk-iii-plus-bnf-w-elrs-hdzero-analog.html) — FPV System: Analog: $206.99 in stock; FPV System: HDZero: $311.99 in stock (checked 2026-07-04) ### Sub250 Whoopfly16 HDZero The Whoopfly16 is a 75mm 1S HDZero whoop built around a one-piece injection-molded duct frame that makes it notably crash-resistant — a durable indoor trainer and smooth park cruiser for beginners who want native digital video. The build centers on an inverted-pusher layout with a one-piece injection-molded duct frame — rigid, crash-resistant, and notably more durable than flexier Meteor75-style frames — with foam bumpers included for the ducts. Electronics are a Redfox A1 F4 5A AIO with built-in SPI ELRS, feeding an HDZero Whoop Lite VTX (switchable 25/200mW) and Nano Lite camera for native 720p60 low-latency digital video on HDZero goggles such as the BoxPro+. In the air it flies like a trainer should: the stock PID tune is smooth and locked-in out of the box, handling both angle and acro flying without retuning — forgiving for beginners and consistent for reflex practice. The 1002 21000KV motors deliver strong, punchy power for the 75mm 1S class, with reserve for outdoor cruising. It sits at the heavier end of the 75mm 1S class — heavier than competitors like the BetaFPV Meteor75 — which costs some efficiency and makes it a locked-in trainer rather than a racing or freestyle machine. Real-world flight time runs around 3 minutes indoors on the 530mAh pack, versus the manufacturer's 4.5-minute claim. Spares are a strong point: Sub250 sells frames, Gemfan 1608-3 props, 1002 motors, the Redfox A1 AIO FC, and A30 530mAh packs individually, and the A30 battery connector is BT2.0-compatible, so common 1S HV whoop packs and chargers work. One platform caveat: the ELRS receiver is SPI, not UART — it binds to any ELRS 2.4GHz radio through Betaflight, but its firmware is baked into Betaflight and must stay version-matched with your radio's ELRS major version. - 75mm · 1S · 39.2g bare · Ducted (visually verified) - HDZero Nano Lite camera · HDZero Whoop Lite · SPI ELRS 2.4GHz (built-in on Redfox A1 F4 5A AIO FC) - Motors 1002 KV21000 brushless · 40mm props - Battery: 1S 530mAh 90C LiHV (A30) - VelociDrone: None Vendors: - [Sub250 (direct)](https://sub250.com/products/whoopfly16-hd-zero-1s-tiny-whoop) — ELRS: $259.99 in stock (checked 2026-07-04) - [Five33](https://flyfive33.com/products/sub250-whoopfly16-bnf-1-6-hd-ultra-light-hdzero-1s-whoop-elrs-2-4ghz-spi) — Default Title: $275.99 sold out (checked 2026-07-04) - [RaceDayQuads](https://www.racedayquads.com/products/sub250-whoopfly16-bnf-1-6-hd-ultra-light-hdzero-1s-whoop-elrs-2-4g-spi) — Default Title: $275.99 sold out (checked 2026-07-04) ### Flywoo FlyLens 75 HD HDZero 2S (V1.3) A 75mm-class (1.6-inch prop) 2S brushless whoop with a full protective ring and a genuine HDZero Whoop Lite VTX, built as an outdoor-capable park flyer and smooth indoor cinewhoop rather than a low-inertia reflex trainer. Built on a carbon-plus-PC Y-frame with a full protective ring and a reverse-thrust pusher layout that keeps props out of the camera view, it pairs a genuine HDZero Whoop Lite VTX and Nano V3 camera with a three-point CNC shock mount that eliminates jelly. The quick-release frame assembles with five screws and the quick-release battery compartment accepts 2S 550-1000mAh XT30 packs, so pack swaps and crash repairs are fast. At 51.5g bare it is the lightest HD variant in the FlyLens 75 family (the O3 version is 79.5g), but around 80g all-up with a 2S pack it flies as a momentum-carrying cruiser rather than a sub-30g wall-bouncing trainer. Flywoo credits the HDZero build with the family's best flight times — 4:30 on a 2S 550mAh up to 8:00 on a 2S 1000mAh — and a 70km/h top speed. The V1.3 revision (April 2024) added a reinforced frame kit and the GOKU F405 HD AIO V2 board with true serial (UART) ELRS 2.4GHz, so it binds and updates like a full-size ELRS quad with any ELRS 2.4GHz radio — unlike SPI-ELRS whoops with their limited update path. Its 720p60 HDZero video is native to BoxPro+ goggles, and the onboard module takes full ExpressLRS Configurator firmware updates (Flywoo EL24P flash target). Reviewers described the platform as notably quiet, stable, and confident in tight indoor spaces. The HDZero Whoop Lite VTX outputs a selectable 25/200mW, and V1.3's 9x9mm motor mounting holes widen motor choice. - 75mm · 2S · 51.5g bare · Ducted (visually verified) - HDZero Nano V3 camera · HDZero Whoop Lite (Whoop Lite bundle) · UART/serial ELRS 2.4GHz (built-in on GOKU F405 HD 1-2S 12A AIO V2, internally tied to UART1; Flywoo EL24P target) - Motors ROBO 1003 14800KV · 40mm props - Battery: 2S 550-1000mAh (XT30) - VelociDrone: None Vendors: - [Flywoo (direct)](https://flywoo.net/products/flylens-75-hd-hdzero-2s-brushless-whoop-fpv-drone) — ELRS 2.4G: $279.99 in stock; TBS CRSF: $299.99 in stock (checked 2026-07-04) - [GetFPV](https://www.getfpv.com/flywoo-flylens-75-2s-bnf-whoop-hd-w-hdzero-nano-v3.html) — Receiver Protocol: ExpressLRS 2.4GHz: $211.99 in stock (checked 2026-07-04) ### Flywoo FlyLens 85 HD HDZero 2S The FlyLens 85 HD is Flywoo's 85mm 2S pusher whoop with full circumferential prop rings and native HDZero 720p60 video — a sub-100g, outdoor-capable park cruiser for pilots who already own HDZero goggles, not an indoor reflex trainer. Build centers on an HDZero Whoop Lite VTX (up to 200mW) and a RunCam HDZero Micro V2 camera for a native, low-latency 720p60 digital feed to HDZero goggles like the BoxPro+. The built-in ELRS 2.4GHz receiver is serial (CRSF over UART), not SPI, so it binds like a standalone ELRS RX and takes full ExpressLRS Configurator updates via WiFi or Betaflight passthrough, staying version-matched with any ELRS radio. Positioned as a smooth-tuned, crash-tolerant backyard and park cruiser rather than an indoor reflex trainer: it is bigger, heavier, and floatier than 65-75mm whoops, and its 2-blade 2-inch props favor smoothness over snap. Full circumferential injection-molded prop rings and the pusher layout let it bounce off obstacles instead of breaking. The stock tune is jello-free with minimal propwash and holds stable HD footage even in high wind (tested around 18mph). Endurance is strong for a 2S whoop — roughly 4-7 minutes depending on pack, running 2S 750-1000mAh HV batteries with included TPU mounts for multiple pack sizes. The quick-detach frame backs a deep spare-parts ecosystem: frames, ROBO 1003 motors, GOKU AIO boards, and prop rings are all sold separately by Flywoo and US retailers. Note there is no dedicated camera lens protection on the frame, so a lens protector is advised for crash-prone flying. - 85mm · 2S · 72.3g bare · Ducted (visually verified) - RunCam HDZero Micro V2 camera · HDZero Whoop Lite (bottom-mounted, MIPI 80mm cable) · UART/serial ELRS 2.4GHz (built-in on GOKU F405 AIO; ELRS Configurator updates via WiFi/passthrough, not SPI) - Motors Flywoo ROBO 1003 14800KV · 51mm props - Battery: 2S 750-1000mAh HV (Flywoo Explorer 1000mAh 2S 80C HV) (XT30) - VelociDrone: None Vendors: - [Pyrodrone](https://pyrodrone.com/products/flywoo-flylens-85-hd-hdzero-2s-brushless-whoop-fpv-drone-choose-receiver) — ELRS 2.4GHz: $389.99 sold out (checked 2026-07-04) - [WREKD](https://wrekd.com/products/flywoo-bnf-flylens-85-2s-hd-85mm-brushless-whoop-w-hdzero-whoop-lite-micro-cam-v2-elrs-2-4-ghz) — Default Title: $365.99 sold out (checked 2026-07-04) - [RaceDayQuads](https://www.racedayquads.com/products/flywoo-bnf-flylens-85-2s-hd-85mm-brushless-whoop-w-hdzero-whoop-lite-micro-cam-v2-elrs-2-4-ghz) — Default Title: $365.99 sold out (checked 2026-07-04) - [GetFPV](https://www.getfpv.com/flywoo-flylens-85-hd-2s-bnf-whoop-w-hdzero.html) — Receiver Protocol: ExpressLRS 2.4GHz: $396.49 sold out; Receiver Protocol: PNP - No Receiver: $113.54 sold out; Receiver Protocol: TBS Crossfire: $226.99 in stock (checked 2026-07-04) ### Flywoo Flytimes 85 HDZero 2S The Flytimes 85 is a light 85mm-class 2S HDZero micro cinewhoop for experienced pilots — a cinewhoop/toothpick hybrid tuned for smooth, quiet, long-endurance cruising, protected by a perimeter bumper rail rather than full per-prop ducts. The HDZero build pairs an HDZero Whoop Lite VTX (up to 200mW) and a RunCam Nano V3 camera for native, plug-and-play 720p60 low-latency video with HDZero BoxPro+ goggles. It runs Flywoo's GOKU F405 HD 1-2S AIO on ROBO 1003 14800KV motors at 56.6g bare, with capable electronics for the class: an F405 MCU, ICM-42688 gyro, a 12A (25A peak) 4-in-1 ESC, barometer, 8MB blackbox, and 6 UARTs. Flywoo co-developed the Flytimes 85 with a photography studio for indoor commercial shooting, and reviewers call it a cinewhoop/toothpick hybrid: a light, efficient indoor and close-quarters cine and cruising quad rather than a bash-proof duct whoop. It flies sub-100g with typical 2S packs — smooth, quiet, and jello-free — and leans on endurance, with Flywoo claiming 8+ minutes on a 2S 1000mAh at only 26% takeoff throttle. Protection is a perimeter TPU bumper rail on a Y-shaped aluminum bracket — no per-prop ducts — so it guards against slow minor bumps while the camera and electronics stay exposed; the aluminum bracket can bend in a harder crash, though a reviewer's bent mounting arm straightened without permanent damage. Flywoo positions it for advanced pilots. There is also no onboard HD recording: the Nano V3 is a 720p live feed only. The GOKU F405 HD V2 AIO carries a serial UART ELRS 2.4GHz receiver — not SPI — so it binds normally with any ELRS 2.4GHz radio and takes full ELRS firmware updates via WiFi or Betaflight passthrough. Quick-release TPU mounts for 550/750/1000mAh packs are included (batteries are not), though battery mounting and prop-guard fitment can be fiddly. Spares are supported: Flywoo sells the frame kit and individual parts, and the kit ships with 8 spare props, sponge pads, and hardware. - 85mm · 2S · 56.6g bare · Partial guard (visually verified) - RunCam Nano V3 (HDZero digital) camera · HDZero Whoop Lite (25.5x25.5 mount, u.FL antenna) · UART/serial ELRS 2.4GHz (built into GOKU F405 HD 1-2S 12A AIO V2; WiFi/passthrough updatable) - Motors Flywoo ROBO 1003 14800KV · 51mm props - Battery: 2S 550/750/1000mAh LiPo (mounts for all three included; batteries not included) (XT30) - VelociDrone: None Vendors: - [RaceDayQuads](https://www.racedayquads.com/products/flywoo-flytimes-85-drone-hd-w-hdzero-runcam-nano-v3-2s) — ELRS 2.4GHz: $335.99 in stock (checked 2026-07-04) - [Pyrodrone](https://pyrodrone.com/products/flywoo-flytimes-85-hdzero-2s-micro-drone-choose-receiver) — ELRS 2.4GHz: $356.99 in stock (checked 2026-07-04) - [Flywoo (direct)](https://flywoo.net/products/flytimes-85-hdzero-2s-micro-drone) — ELRS 2.4g: $279.99 in stock; TBS CRSF: $299.99 in stock (checked 2026-07-04) ### Flywoo Flybee 16 HD (HDZero) The Flybee 16 HD is a 1.6-inch 2S open-prop toothpick-style pusher with genuine HDZero video, aimed at HDZero-goggle pilots who want a nimble outdoor cruiser and light-freestyle machine — its exposed props trade indoor whoop safety for efficiency, speed, and quiet. The build centers on a genuine HDZero Whoop Lite VTX (25/200mW) and RunCam Nano V3 MIPI camera for native 720p60 digital video, all on the GOKU F405 HD AIO V2: an STM32F405 MCU, ICM42688P gyro, barometer, current sensor, 8MB blackbox flash, and Bluejay 48kHz ESC firmware with bidirectional DShot/RPM filtering. At just 45.7g without battery, it is very light for a digital HD quad. With no ducts or prop guards, the open-prop pusher layout trades indoor safety for outdoor efficiency, speed, and quiet. Reviewers describe it as a nimble outdoor cruiser and light-freestyle machine — not a hard-freestyle or indoor quad — with a clean, stable camera mount on soft gummies to damp vibration. Notable prop wash appears during aggressive maneuvers, and the low-slung pusher props complicate takeoffs, landings, and turtle-mode flips. On the ecosystem side, the onboard receiver is a true serial (UART) ELRS 2.4GHz module (Flywoo EL24P on UART1) running real ExpressLRS v3 firmware at up to 500Hz, updatable via the ExpressLRS Configurator over Wi-Fi or Betaflight passthrough — no SPI version-lock. It runs standard XT30 2S packs and ships with TPU mounts for 550/750/1000mAh, 8 spare 1611 props, and a screwdriver. Flywoo claims 4:30 on 2S 550mAh and 6:00 on 750mAh, roughly 70km/h top speed. - 75mm · 2S · 45.7g bare · Open-prop (visually verified) - RunCam Nano V3 (HDZero, MIPI) camera · HDZero Whoop Lite (720p60) · Serial UART ELRS 2.4GHz — Flywoo EL24P receiver onboard GOKU F405 HD 1-2S AIO V2 (ELRS v3.x, 25-500Hz, CRSF, updatable via ExpressLRS Configurator); not SPI - Motors Flywoo ROBO 1003 14800KV · 40mm props - Battery: 2S LiHV 550-750mAh XT30 (Flywoo Explorer series; TPU mounts included for 550/750/1000mAh) (XT30) - VelociDrone: None Vendors: - [RaceDayQuads](https://www.racedayquads.com/products/flywoo-flybee-16-1-6-drone-hd-w-hdzero-runcam-nano-v3-2s) — ELRS 2.4GHz: $200.99 in stock (checked 2026-07-04) ### BetaFPV Meteor65 Pro O4 The Meteor65 Pro O4 is BetaFPV's 66mm-wheelbase 1S brushless whoop and the smallest to carry a genuine DJI O4 Air Unit, tuned soft for smooth cinematic and indoor HD filming rather than racing. Released January 2025, it pairs the Meteor65 Pro frame with 0802SE 19500KV motors and Gemfan 35mm 3-blade props on the Matrix 1S 3IN1 HD FC, purpose-built for 1S O4 whoops: an STM32G473 MCU, a 12A continuous/18A peak BLHeli ESC running Bluejay, onboard serial ELRS 2.4GHz, and a 5V/3A BEC sized to hold the O4 video link stable through voltage sag. BetaFPV positions it explicitly as a cinematic and indoor HD filming whoop, not a racer. The factory tune runs soft PIDs, adapted rates, and an extended throttle range for smooth, stable flying out of the box, and the O4 camera rides on a four-ball shock-absorbing mount that isolates high-frequency vibration to keep HD footage jello-free. A redesigned canopy sets camera angle anywhere from 10 to 35 degrees. The tradeoff is weight: at 28.53g without battery (roughly 36.8g all-up with the recommended 8.3g LAVA 1S 300mAh pack) it is heavy for a 65mm 1S whoop, and the O4 air unit is a lot for this small a platform — reviewer and community consensus is that the 75mm Meteor75 Pro O4 sibling carries it noticeably better. BetaFPV claims a 2:40 flight time, and the soft tune's limited thrust headroom makes it a poor pick for acro or racing. The fitted air unit is the standard, non-Pro DJI O4: a 1/2-inch sensor, 117.6-degree FOV, up to 4K/60 recording to 23GB fixed internal storage (no microSD, no D-Log M color mode), and FCC transmit power up to 1W EIRP. The onboard ELRS receiver is serial (UART), so it takes standard ExpressLRS updates without SPI version-lock, though the BT2.0 battery connector keeps you on BetaFPV-ecosystem 1S packs and chargers. - 66mm · 1S · 28.53g bare (~36.8g AUW) · Ducted (visually verified) - DJI O4 camera (standard unit): 1/2-inch CMOS, f/2.8, 117.6-degree FOV, records up to 4K/60fps to 23GB internal storage (no microSD) camera · DJI O4 Air Unit — standard O4 (non-Pro) unit, 8.2g with camera (1000mW) · Serial (UART) ELRS 2.4GHz, onboard the Matrix 1S 3IN1 HD FC — UART-based, not SPI - Motors BetaFPV 0802SE 19500KV brushless · 35mm props - Battery: BetaFPV LAVA 1S 300mAh 75C (BT2.0); LAVA II 1S 280mAh/320mAh also listed (BT2.0) · ~2:40 (manufacturer claim, LAVA 1S 300mAh) min Vendors: - [BetaFPV (direct)](https://betafpv.com/products/meteor65-pro-o4-brushless-whoop-quadcopter) — DJI O4 / ICM42688: $184.99 sold out; DJI O4 / BMI270: $184.99 sold out (checked 2026-07-04) - [RaceDayQuads](https://www.racedayquads.com/products/betafpv-meteor65-pro-brushless-whoop-hd-w-dji-o4-elrs-2-4ghz) — Default Title: $275.99 in stock (checked 2026-07-04) - [TinyWhoop.com](https://www.tinywhoop.com/products/meteor65prohd) — Default Title: $285.99 in stock (checked 2026-07-04) - [ProgressiveRC (Seattle)](https://www.progressiverc.com/products/betafpv-meteor65-pro-o4-bnf) — Default Title: $239.99 sold out (checked 2026-07-04) - [Pyrodrone](https://pyrodrone.com/products/betafpv-meteor65-pro-hd-1s-65mm-with-dji-o4-air-unit-brushless-whoop-quadcopter-elrs-2-4ghz) — Default Title: $269.99 in stock (checked 2026-07-04) - [GetFPV](https://www.getfpv.com/betafpv-meteor65-pro-brushless-whoop-hd-w-dji-o4-elrs-2-4ghz.html) — Default Title: $298.99 in stock (checked 2026-07-04) ### BetaFPV Meteor75 Pro O4 The Meteor75 Pro O4 is BetaFPV's cinematic 1S HD whoop, built around the standard DJI O4 Air Unit on a roomy 80.8mm frame. It targets pilots who want smooth indoor cruising and real 4K/60 onboard footage rather than racing. BetaFPV stretches the Meteor75 Pro platform to an 80.8mm wheelbase with 45mm triblade props and 1102 22000KV motors to carry the O4's extra mass. The solder-free Matrix 1S 3IN1 HD FC combines the flight controller, a 12A (18A peak) ESC, and a serial ELRS 2.4GHz receiver on one board (analog OSD omitted). A four-ball shock-absorbing mount isolates the O4 camera to kill jello, with a 10-35 degree adjustable camera angle in the canopy. Factory tuning (PIDs, rates, extended throttle range) targets smooth indoor cruising and HD filming rather than racing, and the solder-free design makes setup beginner-friendly. It records real 4K/60 onboard while managing roughly 5 minutes per 550mAh pack (5:30 claimed). At 37.2g dry and 51.4g all-up it flies noticeably heavier than analog whoops, is easily pushed around by breeze outdoors, and dislikes wind. The build uses the standard DJI O4 Air Unit (released January 2025), not the O4 Pro - a 1/2-inch sensor with no 4:3 4K modes and lower max transmit power than the Pro - and it is locked into the DJI digital ecosystem, so third-party goggles are not supported. The serial (UART/CRSF) ELRS receiver takes standard firmware updates over Wi-Fi or Betaflight passthrough.

Its DJI O4 Lite video system keeps the complete quad at 52.2g including the air unit. The Pavo Femto is a 75mm ducted 2S whoop that BetaFPV positions as a compact cinewhoop, built around what the company calls an 'optimized whoop duct.' The ducted frame and small footprint suit it to smooth, steady HD camera work in indoor spaces as well as outdoors. Video comes from the DJI O4 Lite air unit, and control runs through an onboard serial ELRS 2.4GHz receiver, so there is no separate receiver to add. Complete with the O4 air unit fitted, the quad weighs 52.2g. - 75mm · 2S · 52.2g bare · Ducted (visually verified) - DJI O4 camera (standard unit) camera · DJI O4 Air Unit · Serial (UART) ELRS 2.4GHz receiver, onboard - Motors BetaFPV LAVA 1102 14000KV · 40mm props - Battery: 2S 450-550mAh (XT30, not included) (XT30) · ~5:15 claimed (position-hold mode) min Vendors: - [BetaFPV (direct)](https://betafpv.com/products/pavo-femto-brushless-whoop-quadcopter) — DJI O4: $204.99 in stock (checked 2026-07-04) - [Pyrodrone](https://pyrodrone.com/products/betafpv-pavo-femto-2s-with-o4-air-unit-brushless-whoop-quadcopter-elrs-2-4ghz-1) — Default Title: $287.99 sold out (checked 2026-07-04) - [ProgressiveRC (Seattle)](https://www.progressiverc.com/products/betafpv-pavo-femto-o4-bnf) — Default Title: $299.99 sold out (checked 2026-07-04) ### BetaFPV Pavo Pico II (O4) BetaFPV's second-generation 80mm brushless cinewhoop, built around the DJI O4 system for pilots who put smooth footage ahead of speed. Its O4 Bracket II soft-mounts the entire camera cage and air unit on four shock-absorbing balls, eliminating jello. Released in September 2025, the Pavo Pico II redesigns BetaFPV's 80mm cinewhoop around DJI O4. The headline feature is the O4 Bracket II: the whole camera cage and air unit ride on four shock-absorbing balls, a soft-mount that Oscar Liang's review found "completely eliminates jello." A redesigned carbon plate accepts both the standard DJI O4 Air Unit and the O4 Air Unit Pro — brackets for both are included, with pre-tuned PID profiles selectable via OSD. Propulsion is upgraded LAVA 1102 14000KV motors on Gemfan 45mm 3-blade props — a claimed 10% thrust increase over the original Pico, for a 6.35:1 thrust-to-weight ratio with the standard O4. An F4 2-3S 20A AIO flight controller with dual BECs (9V 2A for the HD VTX, 5V 3A auxiliary) is properly specced to power the air unit, and the serial (UART) ExpressLRS 2.4GHz receiver takes standard ELRS firmware updates rather than being locked to SPI. The O4 BNF weighs 53.7g without battery — about 84g all-up with a 2S 550mAh — light for a DJI HD whoop. Claimed endurance is 6:30 on that pack, with reviewers measuring roughly 4.5-5 minutes of real-world cruising, and independent reviews report it handles smooth cinematic lines with little prop wash misbehavior. Frame assembly is simple: embedded nuts, guided mounting points, and just four screws on an injection-molded structure that resists flex and crashes. Running the O4 Pro raises dry weight from 53.7g to 78.6g (about 108g all-up), cuts flight time to roughly 4 minutes, and leaves the Pro camera protruding ahead of the guards, where it is vulnerable in crashes. The standard O4 camera is the image-quality compromise — 1/2-inch sensor, 4K/60 max, 117.6-degree FOV, limited low-light performance versus the O4 Pro — and the stock tune is conservative, with room to optimize PIDs and filters. - 80mm · 2S · 53.7g bare (~84g AUW) · Ducted (visually verified) - DJI O4 camera (standard unit): 1/2-inch CMOS, up to 4K/60fps, 117.6° FOV, f/2.8 camera · DJI O4 Air Unit (standard, NOT Pro) in the BNF version; frame and included second bracket also accept the O4 Air Unit Pro; PNP version ships with no VTX (1000mW) · Serial (UART) ExpressLRS 2.4GHz receiver — not SPI; also sold in DJI SBUS RX version - Motors BetaFPV LAVA 1102 14000KV · 45mm props - Battery: BetaFPV LAVA II 2S 580/680mAh or LAVA 2S 450/550mAh (rigid 16×12.7mm battery slot) (XT30) · ~6:30 claimed (O4 + LAVA 2S 550mAh); ~4.5–5 min real-world cruising per reviews min - The PNP version (no O4 air unit) weighs 39.1g bare, versus 53.7g for the O4 BNF.

Released January 2025, the Mobula7 O4 is an 80mm-wheelbase 2S whoop on Happymodel's M80 frame, spinning HQProp 45mm props on four RS1102 10000KV motors (9N12P, 2.8g each). Bare weight is 38g without battery, and an XT30 pigtail takes widely available 2S 450-650mAh packs. Happymodel claims around 5 minutes of flight time, and a reviewer observed 5+ minutes on a 2S 530mAh. Electronics are full-featured for the class: a CrazyF405HD flight controller with STM32F405 MCU, BMI270 gyro, BMP280 barometer, current sensor, 8MB blackbox, and a 12A BLHeli_S/Bluejay 4-in-1 ESC. The radio link is a genuine UART ExpressLRS 2.4GHz receiver (HappyModel EP 2400 RX target, ELRS v3.0.1 from factory) — not SPI — so it takes normal firmware updates through the ELRS Configurator and offers the full 25-500Hz packet-rate menu. Motors arrive pre-plugged, so crash swaps need no soldering. Video comes from the standard DJI O4 Air Unit — the 8.2g Lite unit, not the O4 Pro. It records real 4K/60 onboard with RockSteady and delivers 1080p/100fps low-latency live view, as low as 20ms with Goggles 3. There is no microSD slot, so recording is limited to the 23GB internal storage, and the 1/2-inch 117.6-degree camera is a step down from the O4 Pro's 1/1.3-inch 155-degree unit. Reviews rate it among the better O4 Lite whoops for build quality and outdoor 2S punch — flips, rolls, and dives that 1S O4 whoops can't match — with quiet, efficient operation and minimal camera vibration despite no soft-mounting. The stock tune draws criticism for unpredictable PID behavior and occasional uncommanded yaw twitches, it handles wind poorly, and it feels heavy in tight indoor spaces, so it fits best as a calm-air backyard all-rounder. - 80mm · 2S · 38g bare · Ducted (visually verified) - DJI O4 camera module: 1/2-inch CMOS, f/2.8, 117.6° FOV, onboard 4K (16:9) 3840x2160 recording at up to 60fps with RockSteady, 23GB built-in storage (no microSD slot) camera · DJI O4 Air Unit — the standard 8.2g 'Lite' unit, NOT the O4 Air Unit Pro; 1080p/100fps max live view, latency as low as 20ms (Goggles 3), 5.725-5.850GHz, <30dBm EIRP (FCC) (1000mW) · 2.4GHz UART (serial) ExpressLRS — built into CrazyF405HD FC, NOT SPI; firmware target HappyModel EP 2400 RX, ships with ELRS v3.0.1, packet rates 25/50/150/250/500Hz, updatable via ELRS Configurator - Motors Happymodel RS1102 10000KV (9N12P, 11x2mm stator, 2.8g each, 1-2S) · 45mm props - Battery: 2S LiPo 450-650mAh (XT30); reviewers favor 530-550mAh for stability over 450mAh (XT30) · ~~5 (Happymodel claim; 5+ observed on 2S 530mAh, up to ~7 claimed with conservative flying) min Vendors: - [Pyrodrone](https://pyrodrone.com/products/pre-order-happymodel-mobula7-o4-2s-80mm-digital-hd-fpv-brushless-whoop-drone-elrs-2-4ghz) — Default Title: $283.99 in stock (checked 2026-07-04) - [RaceDayQuads](https://www.racedayquads.com/products/happymodel-mobula7-80mm-whoop-hd-w-dji-o4-elrs-2-4ghz) — Default Title: $274.99 in stock (checked 2026-07-04) - [TinyWhoop.com](https://www.tinywhoop.com/products/mobula7-o4-2s-80mm-digital-hd-micro-fpv-aircraft-dji-04-installed) — Default Title: $274.80 sold out (checked 2026-07-04) - [GetFPV](https://www.getfpv.com/happymodel-mobula7-80mm-whoop-hd-w-dji-o4-elrs-2-4ghz.html) — Default Title: $297.99 in stock (checked 2026-07-04) ### Happymodel Mobula8 O4 An 85mm 2S brushless whoop from Happymodel pairing its Mobula8 frame with the standard DJI O4 Air Unit — an outdoor machine for pilots who want DJI's low-latency digital video and onboard 4K/60 recording at whoop-class weight. Released December 2025, with US retail from January 2026, the Mobula8 O4 pairs Happymodel's 85mm 2S Mobula8 frame with the standard DJI O4 Air Unit. The electronics are well equipped for the class: a CrazyF405HD AIO carrying an STM32F405, BMI270 gyro, BMP280 barometer, current sensor, 8MB blackbox, and 12A BLHeli_S Bluejay ESCs, driving EX1103 11000KV motors on Gemfan Hurricane 2023 tri-blade props. Video comes from the standard O4 Air Unit — 1080p live view at up to 100fps with low latency, plus onboard 4K/60 recording that stabilizes well in Gyroflow. Happymodel adds its 3.2g FOV-extender lens kit with UV, ND8, and ND16 filters, widening the camera to about 150 degrees, and an angle-adjustable canopy. This is the standard O4 rather than the O4 Pro, so it has the smaller 1/2-inch sensor and no 4K/120 or 10-bit recording. In the air it is smooth, stable, and notably quiet, with around 5 minutes of freestyle on a 2S 550mAh LiHV. Happymodel claims 50g dry; Oscar Liang measured 52.6g dry and 82.2g all-up with a 2S 550mAh pack — heavy for the whoop class, which keeps it squarely outdoors. The receiver is true UART ExpressLRS (v3.0.1) with the full 25-500Hz packet-rate menu and standard ELRS Configurator updates. A no-air-unit version exists for pilots who already own an O4. - 85mm · 2S · 52.6g bare (~82.2g AUW) · Ducted (visually verified) - DJI O4 Air Unit camera: 1/2-inch sensor, 155-degree FOV, up to 4K/60fps onboard recording (approx. 8.2g air unit incl. camera); Happymodel FOV extender pushes FOV to about 150 degrees with the stock lens kit camera · DJI O4 Air Unit (standard 'Lite' O4, NOT O4 Pro); 1080p/100fps H.265 live view (1000mW) · UART ExpressLRS 2.4GHz, v3.0.1, target HappyModel EP 2400 RX (serial RX on UART - not SPI) - Motors Happymodel EX1103 11000KV (9N12P, 3.8g each) · 52mm props - Battery: 2S 550mAh LiPo/LiHV (XT30) · ~~5 (freestyle, 2S 550mAh LiHV) min Vendors: - [Pyrodrone](https://pyrodrone.com/products/happymodel-mobula8-o4-2s-digital-hd-85mm-micro-fpv-whoop-drone-elrs-2-4) — Default Title: $294.99 in stock (checked 2026-07-04) - [RaceDayQuads](https://www.racedayquads.com/products/happymodel-mobula8-drone-hd-w-dji-o4-2s-elrs-2-4ghz) — Default Title: $260.49 sold out (checked 2026-07-04) ### NewBeeDrone AcroBee75 HD O4 Pusher The AcroBee75 HD O4 Pusher is NewBeeDrone's 75mm 2S whoop with a standard DJI O4 Air Unit on an inverted pusher frame that keeps props out of the camera's view. It's for pilots who want the full DJI digital link on a 44g airframe. Released in January 2025, this is a pusher build: the motors are inverted so the 40mm props tuck underneath the Cockroach75 frame. That layout centers the center of gravity, improves aerodynamic efficiency, and gives the DJI O4 camera a completely unobstructed forward view, while a floating camera mount isolates it from vibration. Underneath runs proven hardware: the BeeBrain HD G4 flight controller pairs an STM32G474 MCU with an MPU6000 gyro and a 20A ESC running Bluejay 0.19.2 at 48kHz, with three free UARTs. Flow 0804 14000KV motors spin 40mm HQ Ultralight props, power comes in over XT30 on 1-2S, and the craft weighs 44g without a battery. Video is the standard DJI O4 Air Unit: 1080p/100fps low-latency transmission plus real 4K/60 onboard recording (1/2-inch CMOS, 24GB internal memory). Standard means not the O4 Pro, so expect a single VTX antenna, a 117.6-degree FOV instead of 155, no SD card slot, no D-Log M or 10-bit color, and roughly 20ms latency versus 15ms. The radio link is NewBeeDrone's own UART-based ELRS 3.0 receiver with true dual-antenna diversity and an external crystal oscillator, so it takes normal ExpressLRS firmware updates and provides telemetry. The O4's internal SBUS receiver comes pre-wired to UART4, which means a DJI FPV remote controller works with no added hardware. NewBeeDrone publishes firmware and printable STL files for the frame and mount parts, and backs the quad with US-based shipping and support. - 75mm · 2S · 44g bare · Ducted (visually verified) - DJI O4 camera: 1/2-inch CMOS, 117.6° FOV (14mm equivalent), up to 4K/60fps onboard recording to 24GB internal storage (no SD slot) camera · DJI O4 Air Unit — standard unit, NOT the O4 Pro (single antenna, 1/2-inch sensor, no SD slot) (1000mW) · ExpressLRS 3.0, 2.4GHz — NewBeeDrone UART receiver (non-SPI) on UART2, dual-antenna true diversity with external crystal oscillator - Motors NewBeeDrone Flow 0804 14000KV (double ball bearing brushless) · 40mm props - Battery: 2S 450-850mAh HV LiPo with XT30 (Tattu 450/650/850mAh 7.6V long packs or Tattu R-Line 550mAh 7.4V) (XT30) · ~3:00 with 450mAh 2S (vendor-tested); vendor-claimed 5 min hover/4 min cruise on 550mAh 2S, up to 7 min hover/6 min cruise on 850mAh 2S HV min - NewBeeDrone also sells a 'Pusher Kit with ELRS Receiver' version that does not include a DJI air unit — it is a kit, not a complete BNF, so check which SKU you are ordering.

It's an indoor and tight-space HD machine for pilots stepping up to 2S. Flywoo builds the FlyLens 75 around its GOKU F405 HD 1-2S 12A AIO V2 flight controller — F405 BGA MCU, ICM42688P gyro, 12A BLHeli_S/Bluejay ESC, 8MB blackbox, barometer, and a 9V 2A BEC that cleanly powers the DJI air unit — driving ROBO 1003 14800KV motors on 40mm tri-blade props. The modular carbon fiber and PC frame assembles with five screws; Flywoo doesn't publish an exact wheelbase, so the '75' is a name class. The video system is the standard DJI O4 Air Unit, not the O4 Pro: 4K/60fps recording, a 117.6-degree FOV, 100Mbps max bitrate, and 23GB of fixed internal storage with no microSD slot. A three-point CNC shock-absorbed camera mount is designed to suppress the O4 unit's high-frequency vibration sensitivity for jello-free recording. An 'O4 Wide' variant swaps in a wider 155-degree lens, and Flywoo also sells a separate, distinct FlyLens 75 O4 Pro model. In the air this is an indoor and tight-space machine. The quick-release battery bay ships with TPU mounts for 2S 550mAh, 750mAh, and 1000mAh packs, trading weight against Flywoo's claimed 4 to 6.5 minute flight times while keeping takeoff under 100g. An independent review of the same frame platform (O3 version) found it quiet, stable, and crash-resistant indoors with its flexible Y-structure prop ducts, but underpowered and short on flight time outdoors, especially in wind. On the radio side, the ELRS 2.4GHz receiver is serial/UART (CRSF protocol) rather than SPI, so it takes standard ExpressLRS configurator updates and provides full telemetry; DJI PNP (receiverless) and TBS CRSF builds are also offered. The frame kit is shared across the O3 Lite, O4, and O4 Pro versions, which keeps spares easy to source. - 75mm · 2S · 68g bare · Ducted (visually verified) - DJI O4 camera (standard unit): 1/2-inch CMOS, 117.6-degree FOV, up to 4K/60fps onboard recording, 100Mbps max bitrate, 23GB internal storage (no microSD) camera · DJI O4 Air Unit — standard unit, NOT O4 Pro (Flywoo sells the FlyLens 75 O4 Pro as a separate model); FCC transmitter power spec is EIRP <30dBm, no mW rating published · Serial (UART) ELRS 2.4GHz built into the GOKU F405 HD 1-2S 12A AIO V2 (CRSF protocol, ExpressLRS-configurator updatable) — not SPI; also sold as TBS CRSF or DJI PNP (no receiver) variants - Motors Flywoo ROBO 1003 14800KV · 40mm props - Battery: 2S 550-1000mAh LiPo (quick-release TPU mounts for 550/750/1000mAh included) (XT30 (Flywoo XT30UP)) · ~4-6.5 claimed by Flywoo (4 min on 2S 550mAh, 5.5 min on 750mAh, 6.5 min on 1000mAh) min Vendors: - [NewBeeDrone](https://newbeedrone.com/products/flywoo-flylens-75-hd-o4-2s-whoop-fpv-drone) — ELRS 2.4g: $329.99 in stock (checked 2026-07-04) - [Pyrodrone](https://pyrodrone.com/products/flywoo-flylens-75-hd-o4-2s-micro-fpv-drone-elrs-2-4ghz) — Default Title: $331.99 in stock (checked 2026-07-04) - [RaceDayQuads](https://www.racedayquads.com/products/flywoo-flylens-75-drone-hd-w-dji-o4-2s) — ELRS 2.4GHz: $311.99 in stock (checked 2026-07-04) - [NewBeeDrone (O4 Wide variant)](https://newbeedrone.com/products/flywoo-flylens-75-hd-o4-wide-2s-whoop-fpv-drone-elrs-2-4g) — Default Title: $299.90 in stock (checked 2026-07-04) - [Flywoo (direct)](https://flywoo.net/products/flylens-75-hd-o4-2s-whoop-fpv-drone) — O4 Wide (with ND Filter)/ELRS 2.4g: $319.99 in stock; Drone kit (without O4 Wide)/ELRS 2.4g: $159.99 in stock (checked 2026-07-04) - [GetFPV](https://www.getfpv.com/flywoo-flylens-75-drone-hd-w-dji-o4-2s.html) — Receiver Protocol: ExpressLRS 2.4GHz: $337.99 in stock (checked 2026-07-04) ### Flywoo FlyLens 75 HD O4 Pro V1.3 A 75mm-class 2S whoop built around the DJI O4 Air Unit, marketed by Flywoo as the smallest O4-compatible whoop at 68g dry.

Full injection-molded prop rings and onboard 4K/60 recording make it a protected micro for pilots flying DJI digital video. Released in early 2025, the FlyLens 85 HD O4 mounts the standard DJI O4 Air Unit in a carbon frame with PC injection-molded prop guards. ROBO 1003 14,800KV motors spin reverse-mounted Gemfan 2015 bi-blade props in a pusher layout, and a three-point damped camera platform keeps footage jello-free — reviews of the FlyLens 85 platform confirm smooth results, though they also found it notably loud, especially indoors. The standard O4 unit records 4K/60 at 100Mbps onboard, so no separate HD camera is needed, but storage is the unit's fixed internal memory — roughly 24GB, about 30 minutes of 4K — with no microSD slot. Compared with the O4 Pro version of this same quad, it has a smaller 1/2-inch sensor, a narrower 117.6-degree FOV, 4K capped at 60fps, a single antenna, and lower transmit power. Electronics are well-specced for the class: a GOKU F405 HD 1-2S AIO with an F405 BGA MCU, ICM42688P gyro, six UARTs, DPS310/SPL06 barometer, 8MB blackbox, and a 9V 2A BEC with a software VTX power cut-off switch. The 12A BLHeli_S ESC runs Bluejay 48kHz firmware with bidirectional DShot and RPM filtering, and the onboard ELRS 2.4GHz receiver is true serial UART (Flywoo EL24P on UART1), flashable through the ExpressLRS Configurator rather than an SPI receiver. A quick-release battery bay with TPU mounts takes 2S 550, 750, or 1000mAh packs on a reinforced XT30UP strain-relief connector to trade weight for flight time — Flywoo claims 9 minutes on a 1000mAh and 7.5 on a 750mAh, though platform reviews land well below that.

Released in early 2025, the build centers on Flywoo's GOKU F405 HD 1-2S AIO — a 12A BLHeli_S ESC running Bluejay 48kHz firmware, an ICM42688P gyro, and onboard serial ELRS — driving ROBO 1003 14,800KV motors on reverse-mounted Gemfan 2015 bi-blade props. The carbon frame carries PC injection-molded prop guards, a three-point damped camera platform, and a quick-release battery bay with TPU mounts for 2S 550, 750, and 1000mAh packs. The DJI O4 Air Unit records 4K/60 at 100Mbps onboard, so no separate HD camera is needed; storage is the unit's fixed internal memory — roughly 24GB, about 30 minutes of 4K — with no microSD slot. The three-point damped CNC camera platform produces jello-free footage, confirmed smooth in reviews of the FlyLens 85 platform. It sells in ELRS 2.4GHz, TBS Crossfire, and receiver-less DJI PNP variants. The onboard ELRS receiver is a genuine serial UART unit (Flywoo EL24P on UART1), flashable through the ExpressLRS Configurator rather than baked-in SPI. The box is a complete kit — eight spare 2015-2 props, an O4 UV lens filter, a 90-degree Type-C data cable, a screwdriver, and hardware — and the XT30 battery lead is reinforced with Flywoo's XT30UP strain-relief sheath. - 85mm · 2S · 68.8g bare · Ducted (visually verified) - DJI O4 Air Unit camera - 1/2-inch CMOS, 117.6-degree FOV, up to 4K/60fps onboard recording at 100Mbps camera · DJI O4 Air Unit (standard, NOT the O4 Pro - Flywoo sells a separate FlyLens 85 HD O4 Pro model) (700mW) · 2.4GHz serial/UART ELRS onboard (Flywoo EL24P target, CRSF on UART1, SX1280 RF + ESP8285) - true UART receiver, not SPI; also sold as TBS Crossfire or receiver-less DJI PNP variants - Motors Flywoo ROBO 1003 14,800KV (9N12P, 1.5mm shaft, 3.3g) · 50mm props - Battery: 2S 750-1000mAh LiPo (TPU mounts included for 550/750/1000mAh) (XT30 (Flywoo XT30UP reinforced lead)) · ~7.5-9 claimed (2S 750-1000mAh); ~5 measured on 1000mAh in a review of the heavier O4 Pro build min Vendors: - [RaceDayQuads](https://www.racedayquads.com/products/flywoo-flylens-85-v1-3-drone-hd-w-dji-o4-pro-2s) — ELRS 2.4GHz: $479.99 in stock (checked 2026-07-04) - [NewBeeDrone](https://newbeedrone.com/products/flywoo-flylens-85-hd-o4-pro-2s-led-whoop-fpv-drone-v1-3) — ELRS 2.4g: $479.99 sold out (checked 2026-07-04) - [Flywoo (direct)](https://flywoo.net/products/flylens-85-hd-o4-pro-2s-led-whoop-fpv-drone-v1.3) — Flylens 85 O4 PRO （with UV Filter）/ELRS 2.4g: $429.99 in stock; Flylens 85 drone kit (without O4 PRO)/ELRS 2.4g: $159.99 in stock (checked 2026-07-04) - [GetFPV](https://www.getfpv.com/flywoo-flylens-85-v1-3-drone-hd-w-dji-o4-pro-2s.html) — Receiver Protocol: ExpressLRS 2.4GHz: $519.99 in stock (checked 2026-07-04) ### Flywoo Flytimes 85 HD O4 Flywoo's Flytimes 85 HD O4 is an 85mm 2S micro with TPU prop guards built around the standard DJI O4 Air Unit. It suits pilots mixing indoor and outdoor flying who want prop protection and class-leading 2S flight times. Flywoo builds the frame from a Y-shaped aluminum-alloy bracket with TPU prop guards, carrying the GOKU F405 HD 1-2S 12A AIO V2 flight controller with onboard UART ELRS 2.4G, ROBO 1003 14800KV motors, and 2-inch 2015 bi-blade props. A CNC shock-absorption camera platform steadies the O4 unit, and a quick-release battery bay accepts 2S 550, 750, or 1000mAh packs — all three TPU mounts come in the box. Bare weight is 58.9g. The design was co-developed with a Chinese photography studio for indoor commercial shooting, and endurance is the headline: Flywoo quotes 5m30s to 9m of flight at 75km/h cruise depending on pack. Oscar Liang characterizes it as a hybrid of the Flylens 85 and Flybee20 with lighter prop guards, best for mixed indoor and outdoor flying. It runs the standard DJI O4 Air Unit rather than the O4 Pro; Flywoo sells a Flytimes 85 O4 Pro as a separate model, and this page covers the standard-O4 version. Receiver options span onboard ELRS 2.4G, TBS CRSF, and DJI PNP variants, and a Wide edition swaps in Flywoo's native 159-degree wide-angle O4 lens for a more immersive view. - 85mm · 2S · 58.9g bare · Partial guard (visually verified) - DJI O4 camera (integrated in air unit): 1/2-inch sensor, up to 4K/60fps; stock lens on base model, Flywoo 159-degree wide-angle lens on the Wide edition camera · DJI O4 Air Unit (standard, NOT O4 Pro): 1/2-inch sensor, 4K/60fps, ~8.2g; separate Flytimes 85 HD O4 Pro SKU exists for the Pro unit (1000mW) · UART (serial) ELRS 2.4GHz onboard the GOKU F405 HD 1-2S 12A AIO V2, CRSF protocol - not SPI; TBS CRSF and DJI PNP receiver variants also sold - Motors Flywoo ROBO 1003 14800KV · 51mm props - Battery: Flywoo Explorer 2S 550/750/1000mAh (1000mAh LiHV 80C XT30 officially listed for Flytimes 85); TPU mounts for all three sizes included (XT30) · ~5.5-9 depending on pack (Flywoo figures: 5m30s/550mAh, 7m30s/750mAh, 9m/1000mAh at 75km/h) min Vendors: - [NewBeeDrone](https://newbeedrone.com/products/flytimes-85-hd-o4-2s-micro) — ELRS 2.4g: $313.99 in stock (checked 2026-07-04) - [RaceDayQuads](https://www.racedayquads.com/products/flywoo-flytimes-85-drone-hd-w-dji-o4-2s) — ELRS 2.4GHz: $207.99 sold out (checked 2026-07-04) - [NewBeeDrone (O4 Wide variant)](https://newbeedrone.com/products/flywoo-flytimes-85-hd-o4-wide-2s-micro-fpv-drone-elrs-2-4g) — Default Title: $309.99 in stock (checked 2026-07-04) - [Flywoo (direct)](https://flywoo.net/products/flytimes-85-hd-o4-2s-micro-fpv-drone) — O4 Wide (with ND Filter)/ELRS 2.4g: $329.99 in stock; Drone kit (without O4 Wide )/ELRS 2.4g: $159.99 in stock (checked 2026-07-04) ### Flywoo Flytimes 85 HD O4 Pro Flywoo's Flytimes 85 is an 85mm 2S micro with TPU prop guards, here fitted with the DJI O4 Pro 4K air unit — a camera-first whoop for pilots who want long, smooth indoor and outdoor video with quick-release battery flexibility. The airframe hangs the flight stack on a Y-shaped aluminum-alloy bracket with TPU prop guards. Electronics are the GOKU F405 HD 1-2S 12A AIO V2 flight controller with onboard UART ELRS 2.4G, ROBO 1003 14800KV motors, and 2-inch 2015 bi-blade props. A CNC shock-absorption camera platform isolates the air unit for jelly-free onboard footage, and a quick-release battery bay takes 2S 550, 750, or 1000mAh packs — all three TPU mounts included. Endurance is the headline number: Flywoo quotes 5m30s on a 550mAh pack, 7m30s on 750mAh, and 9m on 1000mAh at a 75km/h cruise. Bare weight is 58.9g without battery for the standard-O4 build; Pyrodrone's spec table lists the O4 Pro version at 79.2g. Flywoo co-developed the Flytimes 85 with a Chinese photography studio for indoor commercial shooting, and it flies like the crossover it is: Oscar Liang characterizes it as a hybrid of the Flylens 85 and Flybee20 with lighter prop guards, best for mixed indoor and outdoor flying — lighter than the Flylens 85 while keeping the prop protection the Flybee20 lacks. It comes in multiple receiver variants — ELRS 2.4G, TBS CRSF, and DJI PNP — plus a Wide edition fitted with Flywoo's native 159-degree wide-angle O4 lens; the base model carries the stock narrow lens, with the wide view available via the Wide edition or Flywoo's add-on lens. The standard-O4 and O4 Pro builds are separate SKUs, so match the SKU to the air unit you want. - 85mm · 2S · 58.9g bare · Partial guard (visually verified) - DJI O4 camera (integrated in air unit): 1/2-inch sensor, up to 4K/60fps; stock lens on base model, Flywoo 159-degree wide-angle lens on the Wide edition camera · DJI O4 Air Unit (standard, NOT O4 Pro): 1/2-inch sensor, 4K/60fps, ~8.2g; separate Flytimes 85 HD O4 Pro SKU exists for the Pro unit (1000mW) · UART (serial) ELRS 2.4GHz onboard the GOKU F405 HD 1-2S 12A AIO V2, CRSF protocol - not SPI; TBS CRSF and DJI PNP receiver variants also sold - Motors Flywoo ROBO 1003 14800KV · 51mm props - Battery: Flywoo Explorer 2S 550/750/1000mAh (1000mAh LiHV 80C XT30 officially listed for Flytimes 85); TPU mounts for all three sizes included (XT30) · ~5.5-9 depending on pack (Flywoo figures: 5m30s/550mAh, 7m30s/750mAh, 9m/1000mAh at 75km/h) min Vendors: - [NewBeeDrone](https://newbeedrone.com/products/flywoo-flytimes-85-hd-o4-pro-2s-micro-fpv-drone) — ELRS 2.4g: $490.99 in stock (checked 2026-07-04) - [RaceDayQuads](https://www.racedayquads.com/products/flywoo-flytimes-85-drone-hd-w-dji-o4-pro-2s) — ELRS 2.4GHz: $491.99 sold out (checked 2026-07-04) - [Pyrodrone](https://pyrodrone.com/products/flywoo-flytimes-85-hd-o4-2s-micro-fpv-drone-elrs-2-4ghz) — Default Title: $538.99 sold out (checked 2026-07-04) - [Flywoo (direct)](https://flywoo.net/products/flytimes-85-hd-o4-pro-2s-micro-fpv-drone) — Flytimes 85 O4 PRO(with UV filer)/ELRS 2.4g: $439.99 in stock; Flytimes 85 drone kit (without O4 PRO)/ELRS 2.4g: $159.99 in stock (checked 2026-07-04) ### Sub250 Nimble65 HD O4 Sub250's Nimble65 HD O4 is a 65mm 1S brushless tiny whoop carrying a full DJI O4 (Lite) Air Unit — at 27±1g bare, one of the lightest ways to fly native DJI digital HD indoors, for pilots who value HD footage over raw agility. The Nimble65 HD O4 launched in January 2025 alongside DJI's O4 release, carrying the standard O4 Air Unit (the "Lite," not the O4 Pro) on a 65mm 1S frame. That unit gives it onboard 4K/60fps recording from a 1/2-inch CMOS sensor and 1080p/100fps low-latency live view, with no separate HD camera needed. The powertrain is Sub250 0702 27000KV motors on HQ 1.2x0.9x3 (31mm) tri-blade props, driven by a Redfox A1 5A AIO (STM32F411, ICM42688-P) with an A30 connector. Claimed endurance is 2 min 30 s on the recommended 1S 300mAh pack. Hauling a full O4 unit with this setup leaves it underpowered for its weight — Oscar Liang's O4 micro comparison judged it "sluggish performance, poor responsiveness." The original release powered the O4 directly from the 1S pack, causing voltage-sag brownouts and video dropouts serious enough that Oscar Liang said he could not recommend it. Sub250 revised the product with a dedicated built-in 1S boost BEC — the current listing is titled "Built in with BEC" — and follow-up reviews confirmed the brownouts are fixed. It sells in ELRS 2.4GHz or PNP (DJI remote) receiver variants. The ELRS receiver is SPI-based on the Redfox AIO rather than a true UART module, so it is tied to Betaflight's SPI implementation and slower to receive ELRS firmware features. Ecosystem support is solid: standard 25.5x25.5mm VTX mounting, a common F411/ICM42688-P AIO stack, and individual spares — frames, hoods, props, motors, batteries — sold by Sub250. - 65mm · 1S · 27g bare · Ducted (visually verified) - DJI O4 Air Unit camera: 1/2-inch CMOS, onboard recording up to 4K/60fps (1080p up to 120fps), 1080p/100fps live view, latency as low as 20ms with Goggles 3 camera · DJI O4 Air Unit — the standard 8.2g unit (community 'O4 Lite'), NOT the O4 Air Unit Pro; current revision powered via built-in 1S boost BEC (1000mW) · ELRS 2.4GHz SPI receiver integrated on Redfox A1 5A AIO (SPI, not UART); PNP variant available without receiver - Motors Sub250 0702 27000KV · 31mm props - Battery: Sub250 1S 300mAh 75C (not included) (A30) · ~approx. 2 min 30 s (manufacturer claim, varies by flight style) min Vendors: - [Sub250 (direct)](https://sub250.com/products/nimble65-hd-o4-65mm-tiny-whoop) — ELRS: $229.99 in stock (checked 2026-07-04) - [Pyrodrone](https://pyrodrone.com/products/sub250-nimble65-hd-o4-65mm-whoop) — ELRS: $292.99 in stock (checked 2026-07-04) - [RaceDayQuads](https://www.racedayquads.com/products/sub250-nimble65-1s-65mm-whoop-hd-w-dji-o4) — ExpressLRS 2.4GHz: $275.99 sold out (checked 2026-07-04) ### Sub250 DollyFly16 HD O4 Pro An 85mm ducted 2S cinewhoop from Sub250 that packs the full DJI O4 Air Unit Pro — 4K/120fps recording with RockSteady stabilization — into one of the smallest ducted airframes, built for indoor and small-scene cinematic flying. Released August 2025, the DollyFly16 is built around the full DJI O4 Air Unit Pro rather than the Lite unit: 4K/120fps onboard recording, a 1/1.3-inch sensor, and RockSteady stabilization. The camera rides on a rubber-damped, tilt-adjustable mount with an included ND8 filter and protective housing. The whole aircraft weighs 88g dry and roughly 120g all-up on the recommended 2S pack. Underneath, a GEPRC Taker F411 12A AIO — STM32F411 processor, ICM42688-P gyro, Bluejay 12A ESC — drives Sub250 1103 14000KV motors on Gemfan 1636-4 props, all mounted to a 2mm carbon plate with injection-molded prop guards. It ships either PNP or with a UART serial ELRS 2.4GHz (ELRS 3.0) receiver, and the AIO carries 16MB of blackbox flash plus Betaflight OSD for tuning and troubleshooting. In the air it is aimed at indoor and small-scene cinematic work, with ducts and a camera housing that protect bystanders and the lens in crashes. Outdoors, RockSteady footage stays smooth in wind that visibly shakes the live goggle feed, though the rubber camera mount shows some jiggle at higher speeds and in crosswind. Reviews measured roughly 3:30-3:45 of indoor cruise against the vendor's ~4min claim. Sub250 sells it direct in PNP and ELRS versions, plus WTFPV variants that omit the air unit for pilots transplanting an O4 Pro they already own; Pyrodrone also carries it. The kit is generous: spare protective frame, extra props, damping balls, the ND8 filter, standoffs, and a full micro tool set.

It ships bind-and-fly with a built-in ExpressLRS receiver, 1103 brushless motors, and full-perimeter prop guards. Oxbot is a newer entrant in the tiny-whoop space, and the Lumo18 is its 85mm, 1.8-inch-class ducted whoop built around the DJI O4 Lite air unit. Buyers choose between a standard-lens O4 configuration and an ultra-wide O4 variant; a lower-tier Power ELRS version ships without the air unit for pilots supplying their own video. The airframe pairs an F435 AIO flight controller with 1103 brushless motors on roughly 45mm props, and integrates an ExpressLRS 2.4GHz receiver so it binds and flies out of the box. An integrated VTX damping mount isolates the camera from frame vibration, and independent reviews of the ultra-wide build have highlighted notably clean, low-jello footage. Full-perimeter ducts enclose all four props, favouring indoor and close-proximity flying over top-end speed. It runs on 2S packs through an XT30 lead and adds a buzzer and wireless app tuning. As with most O4-carrying 85mm builds, all-up weight sits toward the higher end of the class, and real-world flight times on small 2S packs run shorter than the rated figure. - 85mm · 2S · ?g bare · Ducted (visually verified) - DJI O4 Lite air unit (standard lens on the O4 Standard variant, ultra-wide lens on the O4 Ultra-Wide variant) camera · DJI O4 Lite integrated digital VTX · Built-in ExpressLRS 2.4GHz receiver (F435 AIO), bind-and-fly - Motors 1103 12000KV brushless · 45mm props - Battery: 2S LiPo/LiHV ~450-550mAh (XT30) (XT30) · ~up to ~8 (rated); real-world 2S times run shorter min Vendors: - [Oxbot (direct)](https://oxbot.com/oxbot-lumo18-fpv-drone/) — O4 Standard: $259.99 in stock; O4 Ultra-Wide Version: $259.99 in stock (checked 2026-07-04) ### Flywoo Flybee 16 HD (DJI O4) The Flybee 16 HD O4 is a 1.6-inch 2S open-prop toothpick carrying a full DJI O4 air unit for native 1080p60 digital video; at 45.7g without a battery it targets outdoor HD cruising and light freestyle, not indoor whoop flying. The build pairs a full DJI O4 air unit and camera with Flywoo's GOKU F405 HD 1-2S AIO V2 (STM32F405, ICM42688P gyro) on a 1.6-inch carbon X-frame. The camera sits on a 3-point shock-absorbing platform tuned for the O4 unit to reduce jello, and power comes from ROBO 1003 14800KV motors swinging 40mm props. It is an open-prop pusher, not a ducted whoop: the exposed props favor efficiency, speed, and quiet at the cost of indoor and around-people safety, and the low-slung pusher props complicate takeoffs, landings, and turtle-mode recovery. Flywoo quotes 4:30 on a 2S 550mAh and 6:00 on a 750mAh. Four snap-on prop guards are included for pilots who want some protection. The control link is a choice of three: a serial (UART) ExpressLRS 2.4GHz receiver (Flywoo EL24P) that updates through the ExpressLRS Configurator, a DJI PNP option that binds directly to a DJI radio through the O4 air unit, or a TBS Crossfire build. It runs standard XT30 2S packs and ships with 550/750mAh TPU mounts, spare props, a UV filter, hardware, and a screwdriver. - 75mm · 2S · 45.7g bare · Open-prop (visually verified) - DJI O4 Air Unit camera (O4 wide-angle lens; UV filter included on the O4 version) camera · DJI O4 Air Unit · Serial UART ELRS 2.4GHz (Flywoo EL24P) on the GOKU F405 HD 1-2S AIO V2 (ICM42688P) — ExpressLRS v3, not SPI.
