AFAIK the intended airfoil was a NACA2415, but the injection molded panels I've checked all seem to match a 16-16.5% section. Nonetheless, this silly little model is evidence they don't hold it back too badly.
I've nearly finished the 3 view drawing in CAD - I started it at 5pm today. I guess it is a simple design! I already had wing 3 views done and cross sections of the airfoil etc..
I'm thinking I''ll cut and skin a thin glider section wing for it and check out the difference in performance. Landings are already hairy here at home though, need a real field. During the glide, it only seems to climb during base leg or final when the battery has already exhausted itself during the previous go-around. And it glides fast and flat. The belly shape is great for landing, sometimes it skips. I puit Kevlar veil across the bottom 1/2 of the fuse, and silkspanned the rest, sealed it up with nitrate then finished in Lustrekote. Came out light and not too hard on the eyes.
