Happymodel M8 Freestyle HD (Mobula8)
Happymodel
Outdoor 2S — wind-tolerant while still whoop-light
An 80mm 2S bind-and-fly super-whoop built for outdoor , 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 video onboard.
Owner reviews report the Lux camera wires tear easily, and the stock canopy sits directly on the camera wires, creating a pinch point; some owners describe the AIO15 + Lux combination as fragile under hard outdoor freestyle.
Street price varies widely from retailer to retailer for the same BNF kit.
Retailer stock is inconsistent across shops.
The full story
Everything rides on the HDZero AIO15 5-in-1 board — flight controller, genuine HDZero , serial receiver, and 15A 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 . 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 ELRS receiver keeps it fully update-compatible with any ELRS 2.4GHz radio, so it takes normal firmware updates rather than lagging the way SPI-ELRS whoops can.
Pros & cons
Pros
- One of the lightest 2S digital whoops available at under 33.5g bare, giving a large power-to-weight jump over 1S whoops; owner reviews report "a ton of power" and call it one of the best whoops above 65mm.
- True UART/serial ELRS 2.4GHz receiver (not ): full packet-rate menu up to F1000Hz and normal ExpressLRS firmware updates, so it can stay version-matched with your ELRS transmitter — a real advantage over SPI-ELRS whoops whose firmware updates lag.
- Genuine HDZero VTX (25/200mW, channels R1-R8/F2/F4/L1-L8) with the HDZero Lux camera (1/2-inch sensor, 720p60, 155-degree diagonal , ) — plug-and-play low-latency digital video with HDZero BoxPro+ goggles.
Show all 6 pros
- Overspecced electronics for the class: STM32G473 , ICM42688 gyro, 15A-continuous (18A peak) Bluejay 4-in-1 ESC, and a 5V 3A .
- Standard 25.5x25.5mm mounting and whoop-frame compatibility, with individual spares (AIO15 board, Lux camera, motors, frame, canopy) sold separately; the box includes a spare canopy, spare props, and tools.
- Sold through the official HDZero US shop and carried by multiple other retailers (Pyrodrone, RaceDayQuads, Tiny Whoop, Rotorama, MantisFPV).
Cons
- Documented fragility pattern: owner reviews report the Lux camera wires tear easily and the stock canopy sits directly on the camera wires, creating a pinch point — some owners describe the AIO15 + Lux combo as fragile and unreliable for hard outdoor freestyle.
- Outdoor-only character: retailers explicitly state it is too powerful and fast to serve as an indoor whoop, so it will not double as an indoor reflex trainer.
- Battery not included, and it uses XT30 2S packs rather than whoop-style BT2.0/A30 connectors — a separate 2S 550mAh fleet (and matching charger leads) is required.
Show all 5 cons
- VTX offers only two power levels (25mW/200mW), with nothing in between and no higher option for longer-range flying.
- Price varies widely by retailer and stock is inconsistent.
