A fellow visited our club with a rud/elev/throt type of plane. He had built it out of plastic sign material and a piece of PVC downspout material. He put 10in of dihedral in it when it called for 5in. Thought it would be more stable that way. I flew it for him since he was learning. It flew fine. Took off fine and turned OK. It was a plane called a SPAD. Cost him $20 to build. Be good for a first plane. Just about indestructable. Used two yardsticks glued together for a spar. His son laid the wing on the ground and stood on it then we flew it!! I believe the website is
