Auto take off fail


Can anyone help me? Please review the logs of this flight. It’s a pretty big log. Most of the flight was done on a FBWA for testing of the maiden. But on the 1st 5 minutes we did automatic takeoff which we should not have done before normal flight. But I want to know why at the beginning when we did automatic takeoff it failed to take off and crashed. I reviewed the logs myself and found nothing wrong except the fact that the airspeed was higher than the GPS airspeed. Please let me know what I would have to do. I did launch into the incoming air and it was kind of windy. It looks like it was pitching up and down while we were doing that take off.
