I have to be honest with you. We cut our own wings. Mickey Losardo is an unbeleivable perfectionist when it comes to wings and he cuts them. We only bought the Fuse's from Piedmont. So I'm not able to comment on that. He cut a dozen cores because we bought around 10 kits to start. To date I think we have about 6 planes built or very close to go. We took a risk on the plane not really knowing what to expect. The only thing we had to go by was the looks of the plane and the assurance from Dave Guerin that the plane was flying very well in prototype and testing. They fly better than I could have hoped for. Ask Troy he's the expert. Also the quality of the glass was great. We still prime ours with epoxy primer because it makes for a better job in the end, but you could easily get away without it. Mike
