Having some problems with my QAV400, this is the second time it just fell out of the sky. First LiPo went well but half through the second one it flips over and does a recovery just before hitting the ground. I also see some small twisting when flying that I haven't seen before. Had this problem on my TBS Discovery and that time it was a bad ESC.
Will change ESC and motors and go over all solderings tonight :)
Did this flight with my QAV400, OpenPilot CC3D, Tiger 2216-9 11KV, Graupner 8x5, ImmersionRC EzUHF, RangeVideo DX201 DPS Camera, TBS Core OSD and 4S LiPos.
This video is shoot with GoPro HERO3 Black Edition in 1080p@60fps.
