I got my quad in the air for the first time today to do some tuning and hovering, setting of the throttle mid, etc. My setup is alot more powerful than I thought it would be! Anyway, I climbed and sort-of-hovered for a total of about 7 seconds. The it flipped over and crashed inverted after a 25 foot fall. I broke a prop and snapped a motor mount.
Just before the crash, I noticed that it was very jittery in the roll axis, rocking quickly back and forth about the axis. It crashed before I could land. In testing earlier, I noticed that one motor was starting slower and stopping faster than the other three.
I'm thinking that may have failed, or that my vibration is too high, or both. This is my first flight and first quad,so I'm a little lost on where to start and not yet proficient at reading the logs. I hope you can help me. Also, in post-crash checkout, I spun up each motor individually for about 5 seconds w/ props on. 2 of them worked great but almost immediately squealed and stopped spinning, and started to smoke. They are very hot to the touch. They barely hand-spin now. I'm assuming they are toast? What could cause that?

Re: tlog file below- I'm not sure this is the correct one, the altitude should reflect about 20-30 feet max, and the only input I really used was throttle.
Damn I'm lost....
