DJI O4 Air Unit Pro (MP66 Gyro) – Flywoo Modified

 

This is a genuine DJI O4 Air Unit Pro, supplied and professionally modified by Flywoo with the sought after MP66 gyro.

The DJI O4 Air Unit Pro combines a powerful digital FPV link with onboard cinematic recording. Its 1/1.3-inch CMOS sensor records up to 4K at 120fps, supports 10-bit D-Log M colour and provides a wide 155° field of view.

DJI O4 transmission delivers a live view of up to 1080p at 100fps. The dual-antenna 2T2R system automatically selects a stable frequency, with latency as low as 15ms and a maximum stated range of 15km under FCC conditions or 8km under CE conditions.

Why Choose the MP66 Version?

Some DJI O4 Air Unit Pro systems manufactured during 2026 use the newer I469D gyro. Although these units can work correctly in a well-damped and properly tuned build, the I469D gyro can be more sensitive to high-frequency vibration transmitted through the frame, camera mount or coaxial cable.

This version has been opened, converted and tested by Flywoo technicians using the earlier MP66 gyro. The MP66 is generally more tolerant of different frame and mounting arrangements, helping reduce the risk of unwanted shake or jitter appearing after RockSteady or Gyroflow stabilisation.

• Genuine DJI O4 Air Unit Pro
• Professionally converted to MP66 by Flywoo
• MP66 output data rate up to 8kHz
• Suitable for a wider range of frame designs
• No camera calibration warning in the goggles
• Tested by Flywoo technicians before dispatch

Please note: The MP66 gyro improves tolerance to vibration but cannot correct damaged propellers, rough motors, a rigid or compressed camera mount, frame contact or a coaxial cable pulling against the camera.

4K/120fps Onboard Recording

The 1/1.3-inch CMOS sensor can record 4K footage at up to 120fps in 16:9 mode. This provides enough image quality and frame rate for many cinematic, freestyle and long-range builds without requiring a separate action camera.

Normal colour and 10-bit D-Log M profiles are supported. D-Log M preserves more highlight and shadow information for pilots who want greater control during colour grading and post-production.

• 1/1.3-inch CMOS image sensor
• Up to 4K/120fps recording
• 4K 4:3 recording at up to 60fps
• 155° ultra-wide field of view
• 10-bit D-Log M colour profile
• RockSteady 3.0+ stabilisation
• Gyroflow support when electronic stabilisation is disabled
• Maximum recording bitrate of 130Mbps

Low-Latency DJI O4 Transmission

The dual-antenna O4 transmission system provides a clear and responsive live view at up to 1080p/100fps. Racing mode can reduce latency to as little as 15ms when used with DJI Goggles 3.

• 1080p/100fps H.265 live video
• Latency as low as 15ms with DJI Goggles 3
• Latency as low as 19ms with DJI Goggles N3
• Maximum 60Mbps transmission bitrate
• Dual-antenna 2T2R transmission
• Up to eight aircraft supported in Racing mode
• Up to 15km FCC or 8km CE stated range

Quoted ranges are laboratory maximums measured in unobstructed, low-interference conditions. Actual performance will depend on regional settings, antenna installation, interference, terrain and local regulations.

Canvas Mode and Flight Controller Support

Canvas Mode allows compatible flight controllers to send a configurable OSD to the goggles. Pilots can display battery voltage, flight time, GPS information, link data and other important flight information using familiar Betaflight or INAV OSD layouts.

• Canvas Mode support
• Betaflight OSD support
• Betaflight 4.3.0 or later
• INAV 8.0.1 or later
• Support for compatible KISS and FETtec flight controllers

Goggle and Controller Compatibility

• DJI Goggles 3 with DJI FPV Remote Controller 3
• DJI Goggles N3 with DJI FPV Remote Controller 3
• DJI Goggles 2 with DJI FPV Remote Controller 2
• DJI Goggles Integra with DJI FPV Remote Controller 2
• Compatible with third-party radio systems when a separate receiver is installed

Compatibility note: DJI FPV Goggles V2 are not supported. Racing mode requires DJI Goggles 3 or DJI Goggles N3.

Flywoo Modification and Packaging Notice

The MP66 conversion is performed by Flywoo technicians and requires the Air Unit to be opened. Minor service marks may therefore be visible on the unit. These are a normal result of the modification process and do not affect operation.

Flywoo checks the converted system before dispatch and confirms that the MP66 version does not display a camera calibration error in compatible DJI goggles.

This product is supplied without the original DJI retail packaging. Warranty and technical support relating to the MP66 modification are handled through the Flywoo supply and service route.

Operation of this video transmission equipment must comply with applicable local radio regulations. Users are responsible for safe and lawful installation and operation.
