Default Wing skins for Crazy Legs

1/64" plywood is almost impossible to get, but is not really necessary. I use a much cheaper alternative. Poster paper (essentially laminated 24" x 28" card stock) is available at most office supply stores. It usually is three layers thick and has a "grain" to it that allows it to bend to a small radius in one direction but not the other. It will easily bend around the leading edge on most wings without creasing. Therefore, make sure the poster paper you buy has the grain running along the long edge. I have built many foam wings with poster paper and 3M-77 spray contact adhesive and it works quite well. Make sure to seal the skins with covering film (Ultracote) or good paint to keep moisture out of paper and the wing will last for many years.. It made incredibly strong wings on a .40 Astron X-wing biplane by Bill Evans. AeroFred.com has several Bill Evans plans in case you want to build a Bill Evans design.
