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 , not indoor whoop flying.

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
