I too am interested in building a U-2. I've got a full machine shop in my basement including a CNC mill, plasma cutter and a large scale CNC hot wire cutter.

I can do a nice job on balsa or obechie covered foam wings. I use a computer controlled foam cutter to cut the cores and then sheet with a thin veneer followed by a very light (.6 oz) fiberglass cloth. I use very little resin and the entire wing is then vacuum bagged and heated until cured.

If anybody gets the fuselage mold going I'd be willing to work out a deal doing some wings/tail surfaces in exchange for a glass fuse.

Best to all,
