I may have done a stupid thing. I bought a used Phantom 4 Pro, supposedly working perfectly and I seem to have bought a lemon.
All seems fine on the ground but when the thing gets in the air it seems to have a a mind of its own. I get multiple compass errors, speed errors, yaw errors and it’s near impossible to control.
Ive copied a few below

Sorry about the poor formatting. I’ve aligned the IMU, I’d calibrate the compass if I could find the option.
Having resisted the temptation to take a very large hammer to it I’m open to suggestions. No chance of getting my money back on it and I’m reluctant to put good money after bad by sending it to DJI.
Any suggestions folks? Or is anyone interested in buying a faulty Obsidian Phantom 4 Pro with a ton of extras
