Desync can be frustrating even for experienced drone pilots. This is video of me trying to figure out which component is causing the desync. This video will only help people who are having desync issue after a crash.
Usually the esc or the motor is the cause of the desync. In rare cases, pdb or fc is the cause of the desync. Fortunately, all I had to do was replace motor.
