I Crashed my pro P3 a couple of weeks ago and I ordered a new shell and a gimbal. My son did a great job switching everything over to the new shell including putting the micro sd card in, but I have the green light on the gimbal but I get the da da sound like it's trying to update. I've turned it off and on same thing. Also I get a rolling compass error on my screen. Not sure why this is. I think we put the antennas in correctly. Does anyone have any suggestions?
