The gimbal attached to my Phantom 2 is not working. The gimbal will not move when I move the X1 stick on the back of the remote controller when the phantom and the controller are both on. Also, when I plug the controller in to my mac and use the RC software, the software does not recognize any movement when I toggle the X1 stick. All Firmware is up to date for the phantom and for the remote. All other settings have been calibrated. Anyone else have this problem? What should I try next?
