I've read a build log the other day where a bloke built a single seat something-or-other from scratch, and managed to destroy it before even its first official flight. He was just doing some high speed taxiing because the weather wasn't great for test flying, he hit a bump, went airborne, didn't have enough space to bring it down and come to a stop, so he tried to power up and do a circuit, but didn't clear the trees, and turned his new baby into a pile of kindling. Twas a sad and abrupt end to his build log, but fortunately not his life.
