I crashed my P4A a few weeks ago and had issues with the gimbal thermal overload message after. The yaw motor was making noises and was slightly bent. I ordered a new yaw motor last week and it came in. I did some research here and elsewhere and before I took the project on of taking replacing it. I've seen where the old casing has to be retained and used with the new motor because the motor won't be calibrated properly to return to center. My problem is, the old casing is chewed up inside, it's destroyed and not usable. I called an authorized DJI service dealer and they said that the yaw motor would have to be calibrated at the factory and they couldn't do it. So, I'm left thinking my camera/gimbal is just a brick now, and worthless. My only choice is to get a complete gimbal/camera assembly, right?
