Hey folks, I had to replace the shell on my aircraft, well my friend did all the work.. The bird powers up but there is no movement of the gimbal and camera. The vision app connects to the aircraft, I can power up and shut off the motors. I was able outside to do a compass calibration properly. In the app when I try and set RTH altitude, it will not hold. I get no camera view or any gimbal movement whatsoever. I do get the wi-fi extender % of charge, no satelitte count, no battery %. I'm able to slide across the screen from right to left and get a sat view of my area. Any help would be greatly appreciated.
