Hello all. I purchased a P3P with a damaged gimbal assembly for cheap. I figured I'd take a shot at repairing it as only the yaw/roll arms and ribbon cable appear[ed] to be damaged. Here is what's happening after reassembling. The set screw is properly installed on the flat side of the motor shaft. Do I need a new yaw motor, or is something else causing this? I did try a gimbal alignment without success.
