I was flying my hexacopter at a local school on june 22. Everything started out great. I was flying it in auto, loiter, guided, and RTL mode. While i was flying my hexacopter started drifting away because of the wind. At witch point i brought it back and tried moving the throttle down to land it, but the throttle wasn't working. I decided to flip the switch and put it into RTL mode, after that the whole thing died, the motors lost power and fell out of the sky. Im not shure exactly what happend but i think the throttle wire fell out.
