I humbly suggest fusalage shape like WWI Observation Balloon. Think vertical plywood cutout circles with horizontal 2x2 ribs and fabric streched over the frame. A general balloon shape with feet and snout attached should work. I used to make balsa wood gliders when I was a boy. Use recycled wood, plywood, and found items to build and just burn it up on one of the many burn platforms. Hinge half for a DeLorian door. Check DMV,s guidelines. Has application deadline passed?
