TRX 4 FPV Mount. for DJI 03 Air Unit

This is an FPV mount designed for the Traxxas TRX-4 using the DJI O3 Air Unit. The mount installs using the existing screws and screw holes on the driver’s side of the TRX-4—no drilling required.

The DJI O3 Air Unit is mounted using 30-lb double-sided tape (any strong double-sided tape should work). The camera is also secured with double-sided tape, and the antenna is attached with a zip tie.

The O3 Air Unit is actively cooled using a 30×30 mm fan.

• Uses the stock DJI O3 Air Unit power cable
• Strip the red and black wires, solder to the TRX-4 battery leads, and seal with liquid electrical tape for waterproofing
• 2S–3S: Safe to connect directly
• 4S and above: BEC required
• Gray, yellow, and brown wires are not used—seal them off only

Compatibility

• Designed for Traxxas TRX-4
