Only second flight.  Can't  use the slider to move the camera up and down until I land! (Motion controller).  Any help?  Thanks.  John

Had the same problem and found it in the online manual but you can only move it with the motion controller while on the ground or landing.

Hello there Cloudsuck. Thank you for reaching out and for this inquiry. The Gimbal Tilt Slider on the DJI Motion Controller can be pushed up and down to adjust the tilt of the gimbal ( only available before takeoff, during RTH or landing ). Thank you.

Thanks all. Works as intended then!  JohnFound the on-line manual!!  Great.
