The Dually will be my first Cluster HPR. It is almost 4 feet tall and 4 inches wide. I wanted to set it up with two 38mm motor tubes to be able to fly it on two J350W motors. This will be a single parachute deployment without electronics. The RockSim picture shows a streamer, but I think I'm going with a small chute. The fins and centering rings will be made out of 3/16 Midwest birch plywood. The entire rocket will be fiber glassed. Estimated altitude is 7950 feet with the right delay.
