Installation Guide
Upon receipt of your DJI O3 Air Unit, attach the air unit onto the aircraft before proceeding. For a step-by-step guide to installing your device, refer to the steps below.
1.  Insert or solder the 3-in-1 cable plug into the socket or solder joints of the aircraft flight control board.
* The cable sequence of different flight controllers may be different. It is recommended that you check whether the cable sequence is correct before attaching and using.
2.  Mount the air unit onto the aircraft, and check whether it is installed securely.
3.  Arrange the camera coaxial cable to avoid winding with other cables.
4.  Fit four screws in each side of the camera module. (Note that the depth of the screw hole is 2 mm. Make sure not to tighten the screw too much. Applying too much pressure will snap the screw, and thereby damage the circuit or FPC within the camera.
5.  Mount the antenna module on the aircraft, and check whether it is installed securely.
6.  Arrange the cables, and secure the aircraft with screws.

I read in a DJI installation guide the air unit will cool better when mounted direct to the carbon fiber plate to help with cooling; makes perfect sense, more thermal mass.
So, my question… would it make sense to use thermal paste as well? I have NO idea if there are any long term effects of thermal paste direct to CF… I’m sure studies have been done!
By the way, I lost track of that document... if anyone has a link please post it!

Hey,
Newbee here (really :-))
I have DJI FPV, and I am considering the upgrade from the installed O2 to a O3
I understand that all ok with the google v2 and remote controller
My questions...
- Is it easy to install?
- Will it work with the Motion controller?
- Does it worth it?

Thank you!

Hello,
I have the DJI O3 air unit connected to my Goggles 2 and Remote V2. Everything seems to be working fine but I cannot adjust the expo/gain or button options for the DJI Remote V2. I would prefer to use the DJI Remote V2 with this setup but the sticks are way too sensitive and need some expo. I am forced to use my external remote.

Please fix the Expo/Gain and Button Options on the DJI Remote V2 they are grayed out and not selectable.

Thanks,
Bob
