Uprightdave did display a road bike that used a Zzipper front piece and lycra stretched over a foam tail section. He cruised at 27 mph. I have a photo somewhere. I also have a National Aerocargo front piece that attaches to the handlebar and fork. It is the combination of a nose cone and a tail section that gives the best results. Sailplanes use either a space frame and aluminum skin or a composite monocoque. The SZD-9 bis Bocian 1E sailplane plans are available free (sheet 1) and I would look at making the Kamm tail at bulkhead 6.
