dox,
Sorry about your wing failing, but I think it may be time to let it go. My cap has 300+ flights on it with a 50cc and it is in awesome shape. Snaps are awesome. I do think a 50cc is a bit much for it as well. Although, mine is way too much fun to consider putting anything else on it. You can see from the video that my wing is plenty strong. You got a bad piece of wood, plain and simple.
