BetaFPV O4 Air Unit Bracket II – vibration-damping mounting bracket for DJI O4 Air Unit
BetaFPV O4 Air Unit Bracket II is a mounting bracket for installing a DJI O4 Air Unit video system on a Pavo Pico II drone frame. It combines a camera mount, vibration damping and an antenna holder in one assembly, making it suitable for both new drone builds and replacement of an existing mount.
Integrated vibration damping
The camera is secured with four screws, while four soft damping elements help reduce vibrations transmitted from the drone to the camera. This design helps minimise vibration-induced image distortion, commonly known as the jello effect.
Unlike the first-generation design with separate camera dampers, Bracket II uses an integrated damping system. It is designed to simplify assembly and reduce vibration issues caused by installation.
Adjustable camera angle and antenna mount
Camera tilt can be adjusted from 5° to 35° to achieve your preferred viewing angle. A dual-hole mounting design allows camera position adjustment and secure fastening.
An antenna holder on the extended rear section is secured with two screws. It keeps the antenna in place and complements the camera and video transmitter mounting arrangement.
Lightweight construction and compatibility
The mounting bracket is made from polypropylene (PP) and weighs 4.1 g, according to the manufacturer. Confirmed compatibility covers the Pavo Pico II frame and DJI O4 Air Unit video system. Compatibility with other frames or video systems must be checked separately.

Package contents
The mounting bracket kit includes a top plate, a bottom plate, two 5.8 GHz video transmitter antennas, six 8 mm shock-absorbing balls and six 1.5 mm shock-absorbing pads. Six M2 × 4 screws and eight M1.4 × 6 screws are included for installation.
