Hello everyone! I have a rather strange experience with my Phantom2 V+. For three times now it happend to me. When i'am flying my Phantom and land it on the ground to check something out it tumbles the moment i want to takeoff again. The first two times it fell backwards and the last time it fell forward. Do i have to completely restart my Phantom after i landed it or is something else the problem? Does anyone have a similair experience? Please share! Thanks!
