I'm having a problem with my camera not facing forward. I've already done an imu calibration, gimbal calibration, and checked that the setscrew that holds the gimbal onto the shaft is in line with the flat on the motor shaft and the setscrew is tight. When the Phantom is sitting flat on a table the camera is aiming to the left a few degrees. I can move the camera by hand from stop to stop and it actually turns further to the left than the right. I can't see anything bent but that seems like it has to be for it to be moving further when it hits the left stop. Any ideas of anything else to look for? Thx
