I had a P3 Pro crash that appeared to bend the gimbal yaw arm and the repair shop insisted on replacing the camera. I purchased a replacement yaw arm, but I noticed the original arm was not really bent -- it had been pushed out of position on the shaft. When I attempted to loosen the set screw, I discovered it was partially stripped! Unfortunately, I only succeeded in stripping the screw completely. Anyone know the best way to extract the stripped screw?
