Well, I finally got my quadcopter w/ APM 2.0 built and flying, and crashing. I was so happy to be flying that the I think I ran below voltage threshold on ESC, and lost power. I still need to confirm in logs. In any case I need a new frame. Here's some photos (before crash) and video (crash at end). Any advice would be appreciated, I made a lot of educated guesses on components.
