RE: Avistar
Being broken after the crash doesn't mean broken before the crash. The nose down could have been caused by pilot error. Dropping the nose could be the result of a stall (pulling up to hard on take off), or simply being out of trim. After the plane was up, you probably just released the elevator. If the plane wasn't trimmed, the nose drops, and your reflexes are not good enough to correct. On a maiden flight, I never quit my climb out or drop the throttle until I've got at least 200 feet of air between the plane and ground. I also prefer to have another person standing with me to help adjust the trim while I keep the plane from crashing. Not normally needed, but their there if I do.
Sorry to hear about the crash. Hope the repairs aren't to difficult.
