NO Original package (I469D)
HD digital FPV transmission
O4 HD link, 4K/120fps video, dual antennas, Canvas Mode OSD, and 15ms Racing mode.
Quick Answer
It combines O4 HD transmission, dual antennas, and a 1/1.3-inch image sensor that records up to 4K/120fps, so compact FPV builds can capture wide HD footage without carrying a separate action camera. Transmission range reaches up to 15km, while Racing mode can lower latency to 15ms and support up to 8 pilots at the same time.

Gyroscope notice
FLYWOO's engineering team found that the I469D gyro used in 2026 O4 Pro production can produce RockSteady stabilization artifacts on some frames. Swapping to MP66 removes the issue without changing normal O4 Pro functions, but MP66 chips are discontinued and replacement stock is limited.
Recommended FLYWOO builds
For the O4 Pro Air Unit with the I469D gyro, the safest choice is a frame that was tuned around it. These FLYWOO models combine a dedicated damping structure, matched power setup, and whole-aircraft tuning, so pilots can get MP66-like smooth footage without the RockSteady shake seen on some untreated frames.
Best for pilots who want a compact long-range build with O4 Pro image quality and FLYWOO's tuned vibration control.

The camera records up to 4K/120fps and supports 10-bit D-Log M color. For many builds, that means wide HD footage without adding a separate action camera.
Racing
Racing mode lowers latency to as little as 15ms and supports up to 8 pilots in the same race. Live view is listed at 1080p/100fps.
OSD
Canvas Mode and Betaflight OSD support give pilots control over the flight data layout shown in the goggles, so battery, link, and flight information can stay readable.
DJI O4 Air Unit Pro is an HD digital transmission system built on DJI's O4 technology. It is made for pilots who want low-latency control response, a stable digital link, and onboard HD recording in one compact setup.
The dual-antenna design automatically selects a stable frequency and supports transmission range up to 15km. A 1/1.3-inch image sensor records up to 4K/120fps, giving compact FPV builds wide, high-definition footage without adding a separate action camera.
Racing mode brings latency down to as low as 15ms and supports up to 8 pilots racing at the same time. The lightweight design is intended for 2-inch and smaller frames, making it flexible for indoor builds, mountain routes, and creative FPV setups.
