Beautiful airplane, very sad to see it destroyed. I hope you build another!
Frank - Full bore into concrete does BAD things to engines and everything else. If you've ever attended a pattern contest held at a military field you get to fly off concrete - nice and smooth (I believe military runways are concrete that is 6 feet deep) and absolutely no 'give' if you crash. The '83 Nats at Westover AFB had interference problems on 1 or 2 frequencies resulting in some spectacular crashes - complete airframe and component destruction; a bit disheartening [

].
