Hi Dan, I think the wood built-up wings have more possibilities in wing type design than foam; your dad must have been very talented to make a foam elliptical wing. I've already built my elliptical wing panels and the hardest part was rounding the leading edge, the jigs make alignment and sheeting relatively easy.

After about 5 hours the stab panel was pulled and the other panel is in the press now. Here are several pictures; the Poly-U glue has expanded around the spars and ribs, a hole near the tip is cut through the skin to locate the waste portion when the elevator is cut off - a leading edge will be attached to the elevator portion just like in a foam wing.
