After about 20,30 minutes of operation, the gimbal feels as if the motors are catching on something. When doing this several times at once, the stabilization fails and the camera goes to one side, unable to be stabilized. It is very unfortunate that this happens in the past an important filming. If I close the gimbal immediately and then open it, do the same thing, you would calibrate every time the problem happens but without any effect.
What could I do, how could I solve this problem?
