Well done!!! Given that you are with the EAA and built a biplane, I'd like to ask your advice. I have noticed all gliders are monoplanes. I have a "home built glider" (kind of like the EAA version for gliding) and I also have to have the "Experimental" wording on my plane. . . I was wondering, if I built and extra wing on my glider, kind of making it a biplane glider, I would in theory increase the glide slope. Glider speeds max out at about 150mph and generally fly at 50mph. . . Would it be a bad idea to try turn my glider into a biplane/glider?
Generally speaking, adding a second wing to a glider would create more drag than lift produced, so it wouldn't be beneficial. To compensate for the additional drag produced you would actually need a longer slender single wing. A good subject to study about this would be wing aspect ratio. Thanks for asking!
