Quad Copter Maiden Voyage

The first time I built this copter it only hovered for a few seconds before I had to abort. There were several reasons: potentially bad parts, a potential short, and no thread locking compound on the props. I replaced the ESC's and the motors with RC Man Child 30A ESC's and 3407 motors. Once all of the preflight was completed, the copter was stable and hovered fairly well. I was able to fly it extensively before crashing it into a parked bicycle and breaking one prop. Fortunately I have spares for just this reason.
