Happymodel Mobula6 HDZero (V3)
Happymodel
The original whoop (2023)
The original HDZero digital tiny whoop: a 65mm 1S brushless HD craft on the two-board Whoop Lite and Nano Lite camera stack, aimed at HDZero goggle owners who want an indoor cruiser with native 720p60 digital video.
Newer versions: Happymodel Mobula6 Race HD ($225.99, $32.69 less, lighter) · Happymodel Mobula6 Freestyle HD ($235.99, $22.69 less, lighter)
Some retail stock is the older SPI-receiver revision, which only binds to ELRS v2 radios. Confirm you're getting the V3 (UART ELRS, A30 connector) before ordering.
The camera-to-VTX link is a MIPI ribbon cable; if it works loose in a crash the VTX can overheat and be damaged. The stock VTX heatsinks were removed in this install to save weight.
Replacement digital-stack parts are getting harder to source — the two-board Whoop Lite VTX has been superseded by the Whoop V2 VTX.
As a legacy model it typically sells for more than the lighter, newer AIO5-based Mobula6 Race HD and Freestyle HD, despite being heavier.
The full story
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 receiver for a true receiver running 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 Replacement digital-stack parts are thinner, though: the Whoop Lite VTX has been superseded by the Whoop V2 VTX.
Pros & cons
Pros
- Native HDZero 720p60 digital video pairs directly with HDZero BoxPro+ goggles — reviewed image quality indoors is excellent with hardly any breakup or static
- V3 has a true UART ELRS 2.4GHz receiver shipping ExpressLRS v3.0.1, so it binds directly to any ELRS 2.4GHz radio on current ELRS v3 firmware and stays updatable through the ExpressLRS ecosystem, unlike SPI-receiver whoops
- Switchable 25mW/200mW VTX output with SmartAudio covers both multi-pilot indoor etiquette and range headroom
Show all 6 pros
- V3 flight controller adds onboard blackbox and ships bind-and-fly on Betaflight 4.4.2 with a spare canopy, spare props, and tools in the box
- GNB A30 battery connector also accepts BT2.0-plug packs, covering the two most common modern 1S connectors
- Mobula6 platform spares (frames, canopies, EX0802 motors, Gemfan 31mm props) are cheap and widely stocked
Cons
- Heaviest of the Mobula6 HD family at 25.7g bare (the newer AIO5-based Mobula6 Race HD is 19.3g, HD 19.6g); the reviewed platform feels underpowered outdoors, handles wind poorly, and tends to wiggle on dive recovery — it is an indoor cruiser
- Short flight time: about 2 min 45 s measured on a 1S 300mAh with the lighter 23.8g 2022 original, and the V3 is roughly 2g heavier
- Camera-to-VTX link is a MIPI ribbon cable the reviewer wished was better secured — if it comes loose in a crash the VTX can overheat and be damaged, and Happymodel removed the VTX's stock heatsinks in this install to save weight
Show all 6 cons
- Replacement digital-stack parts are drying up: the Whoop Lite VTX is sold out/backordered at Tiny Whoop and absent from the HDZero US store, having been superseded by the Whoop V2 VTX
- Poor value in 2026: the ELRS variant at rcdrone.top costs more than the lighter, newer Mobula6 Race HD or Freestyle HD at US retailers
- Happymodel's own rcdrone.top listing still carries the older SPI-revision description (23.5g, PH2.0 plug, SPI ELRS that only binds to ELRS v2.0 TX firmware) — buyers should confirm the shipped revision is the V3 with UART ELRS and A30 connector, since an old-stock SPI unit is a binding headache with your ELRS radio on ELRS v3
