Yep... I actually built the same one when I was much younger and buried it, full throtle, into the ground. Did a snap roll and the control surfaces somehow got stuck in that position, so it snap rolled itself about 40 times until it hit the ground... pretty much nothing left.

It's a little silly on my part for chosing this plane too. I am also building a super skybolt with a YS110, as I've always wanted a biplane, but I konw they are notoriously unforgiveable when mistakes are made. So I decided to build a 'beginner' plane to re-learn on. A sportster probably wasn't the most intelligent choice on my part! =/
