I encountered a strange issue. I charged my phantom 3 4k took it out to fly and went to tilt the camera with the gimbal wheel on the remote control but it will not respond. I always take the gimbal support and foam piece off before turning on the drone. It has only been flown 6 times, not been crashed, and the c1 button functions properly changing the camera from facing forward to facing down. I have re-calibrated the gimbal and imu and it still isnt responding to the gimbal wheel. Any help is greatly appreciated.
