Thanks to Keith for providing the actual issue date, I was able to look it up quickly. It from a series of articles in Air Trails about stunt design, and was an entry to a contest related to it. It was designed by a Mr. James M.Denker, of Egypt, Massachusetts. There was no real name applied to the design, and the heading for the article just says "Aerobatic Aces" and not much in the way of specifics on the design. Lots of formulas and discussion about aspect ratios and wing loadings. Much like a typical day here on Stunt Hanger! I have always been a fan of flying wings, delta shapes and such, and thought about this design quite a bit in my early days and one that might be quite a bit different to take to VSC, just never did get around to it. I still find it kind of appealing, though.
Type at you later,
