A compact, 3D-printed two-stage model rocket designed for classic Estes-style motors. This build uses a C6-0 booster stage to kick off with a strong initial boost, followed by a B6-4 upper stage for a smooth second burn and parachute deployment. Lightweight, modular, and easy to assemble, it’s a great project for hobby rocketeers looking to explore multi-stage flight with reliable, commonly available engines.
