Not being an aeronautical engineer, it may seem crazy to propose such a route, BUT I've got 4000 flight hours with a lot of them in military recon a/c. Now I'm retired, haven't got much money, but still love to fly around the tree tops slowly. I've got some ideas that might interest other guys like me, who would like to help design, or assist in the design and possibly help find some free professional assistance for a very light, slow flying, easy to build. cheap bird.
