So I bought the Integra goggles (the ones with the integrated battery) after I asked the DJI seller if they would work with the RC controller for flying my M3P and he was positive. Then I realized that flying FPV my M3P with RC is not authorized by DJI. I managed to do it anyway after watching a video on YouTube but it is not the best experience.
No head tracking, no extra video feed on the RC.
Why on earth won't they make their own controllers compatible?
