The full story
The build pairs a full DJI O4 air unit and camera with Flywoo's GOKU F405 HD 1-2S 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 , not a 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 () 2.4GHz receiver (Flywoo EL24P) that updates through the ExpressLRS Configurator, a DJI 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.
Pros & cons
Pros
- Full DJI O4 air unit for native 1080p60 digital HD, on a shock-absorbing camera platform tuned to reduce jello
- Very light for a digital HD quad, and the open-prop layout favors efficiency, speed, and low noise versus ducted whoops
- Serial (UART) ExpressLRS 2.4GHz option that updates via the ExpressLRS Configurator, plus DJI-radio PNP and TBS Crossfire choices
Show all 5 pros
- Runs standard XT30 2S packs and ships with TPU mounts, spare props, and tools
- Four snap-on prop guards included for pilots who want some added protection
Cons
- No ducts and fully exposed props make it a poor choice for indoor flying or flying near people
- Low-slung pusher props sit close to the ground, complicating takeoffs, landings, and turtle-mode flips
- Carrying the heavier O4 air unit on a light toothpick leaves little crash headroom
Show all 6 cons
- Short endurance typical of the class, roughly 4 to 6 minutes per 2S pack
- Requires DJI goggles for the O4 feed; not compatible with analog or goggles
- Heavier and pricier than the HDZero edition of the same airframe, reflecting the cost of the O4 air unit
