HUH??

Man Ive heard a lot of reasons for misshaps, but, ailerons moving too far????
OK, even if the ailerons have too much throw, wouldnt that just make it ROLL faster??
I understand its a trainer, but seems itd have to be at beyond trainer speed w/ barn door ailerons to have structural failure??
Think maybe there was a little ca left out or something???
Just a dumb thought.
