Totally scratch built model rocket. Nosecone made from blue styrofoam, body tube is recycled wrapping paper tube, all centering rings homemade from poster board, 22" parachute made from a trash bag, 3mm balsa fins laminated with paper. 24mm motor mount. This launch was done with a C11-3 motor. It should also fly well on a D12-3. As you can see, it went rather well, except for maybe the spiraling parachute descent. The rocket was naked(unpainted) until I was sure it would survive.
