Hi, When i put my Phantom 2 on the gimbal. it looks like he is calibrating and testing his movements for a few seconds. I think This is normal. But when i wait and not start the motors i see that the gimbal slowly slide to left with my gopro. It is not standing straight ahead which i think this is normal. When i fly with is the gimbal Works normal (i think) the recordings looks normal. Sometimes the gimbal is making weard noise. Is this normal behavior?
