Strange Crash

I finally got my Hex back together tonight and upgraded to the external compass I went through the setup routine and took it out for its re-maiden flight. After throttling up to "almost take off" the Hex did a complete flip from front to back. I had NO time to cut throttle or pull back on the stick it was that quick.

I have looked through the logs and I can see no smoking gun as to WHY this happened. Can someone who is good with logs look over these and tell me what might have happened?

Thanks!!!!

Setup: stock from load

APM 2.5 (external compass)

Hex

1000kv motors

10 4.7 props

EDIT:

I did notice that the roll/ pitch graphs where all kinds of screwy... don't know if it was a setup thing, or...

    Instant flip on takeoff is usually 1 of 2 things. Double check your APM orientation and props. Make sure your props are in the correct place (normal and pusher props) and rotations are right (CW and CCW).
