I am thinking about building a Wag-Aero Sport Trainer. I know that is is supposed to be a J3 clone, but how close is it? The reason I am asking is because I really don't want to weld a fuselage up myself, and I know the pre-welded fuse from Wag-Aero is a bit pricey. I was considering buying a J3 fuse, then building the Wag-Aero wings, tail etc to finish it off. Anyone gone this route before?
