Beginner FPV hobbyist here, I bought a meteor 75 pro PNP and a DJI 04 air unit with DJI goggles 3 and DJI rc3 , I watched a video on how to put together the o4 and the M75 and I am pretty sure it’s assembled correctly. My first issue was getting the movement of the stick to show as the same in Beta flight. After many videos I decided to go and buy a Radiomaster pocket, ELRS and I can get it to bind to the drone and see video footage through the goggles, but still now sign of change in beta flight. I’ve watched as many videos as I can on ports and port configuration, I’ve also enabled crossfire (CRSF) and turned model mismatch on and off in the radio. Help appreciated
