Aside from the dinosaur raptor rocket for my son, I've had another raptor idea in my head ever since I made my upscale Estes SR-71. The F-22 design I came up with is for a twin BT55 body tube for a two motor cluster. Aside from a 3D printed nose cone, the rocket/plane will be made from balsa and paper to shape the fuselage to the wings. I do have a Rocksim model to help figure out CP. I'm thinking of using 24mm motor mounts, but with the maiden on C6-3s in adapters.
