John, The foam wings are the easy part of this build. I am in the middle of one right now that I started 2 years ago. It took so long because I had surgury just after starting it, & then we moved from Ohio to N. Carolina. I hope to get back to it really soon here as soon as I get more hobby things unpacked & my room set up. The hardest part was getting the planking to fit correctly around the engine neceles & then the fiberglassing of the entire plane for paint. It would have been easier to cover it with iron-on film, but I went for the paint method. Other than those items, its a fairly normal build. Looks great. I will be powering with 2 O.S. 70 four strokes. If you decide to build & need help, just give a yell & I'd be happy to help. Bill
