I took my P3 out to survey some land and when I went to warm it up I noticed the camera started to slowly tilt down? I corrected it by moving the camera to the starting position then it slowly went back down. What gives? It's fairly new with 3-4hrs flight time, I've never crashed it, the only thing I can think of was I left it in my truck over the weekend durning 100-101 temps in Texas. Has anyone experienced this before?
