Had a crash and now when connected to mission planner yaw is continuously changing. It starts at 360 and counts down. I created a short video showing this in mission planner. Flying is of course impossible, the copter just starts to yaw out of control.
Any suggestions to fully diagnose this or correct it? I suspect the gyro is messed up. I read about reflowing but would appreciate more details on how to do this. I do have a heat gun.
