The plans don't explain how to build a wing from balsa, but the plan does have a airfoil, and I used that to build a built-up wing. I made a center section, and two side pieces. Essentially, I cut a ">" shaped notch into the face of each airfoil wing rib, so that I could glue in a 3/8" square leading edge. I sheeted the back end top and bottom so that it shaped a nice trailing edge. I then used spruce for an upper and lower spar, and they stick out past the surface of the wing rib the thickness of the balsa sheeting I used. Next, I sheeted a "D" tube in the front from the leading edge up to the spars on the top and bottom. Finally, I made cap strips for the top and bottom of the airfoil ribs.. Don't worry if I'm not making sense- a pic is worth a 1000 words(see below).. I sheeted the entire center section, and I made two 3/16" thick balsa airfoil ribs that I then tapered (thinner on top edge) to fit between each outer wing section and the center section, so that there was no gap when each outer section was propped up to give the wing proper dihedral. I also used thicker airfoils (can't remember if it was 1/4" or not) glued onto the end, and then rounded, for wing tips. I think this might have been 3/16" balsa though, to save weight. If I recall correctly, I just put 3 CD jewel cases stacked on top of each other, and propped the wing tips with those jewel cases on each side- High tech, huh? It came out plenty strong, and light. I'll even go so far as to say it looks pretty good too!

Here's some pics:



Also, you can buy a kit still- Thunder Tiger bought the rights to make some of the Ace simple series kits again, of which this plane is one of them.
