I have a DJI Phantom 3 Professional. Flies well, gimbal works well, but the camera is "centered" off center. By that, I mean that when it's sitting powered on and idle, the camera looks about 30 degrees to the right. I've done an IMU calibration and several gimbal calibration, and it stays this way. Any suggestions what might be wrong, or how to troubleshoot or fix? My theory is that something is just bent, but it doesn't appear to be. It's almost as if the "top" gimbal motor think center is 30 degrees to the right. Thanks for your thoughts or suggestions!
