I recently was lucky enough to get a bunch of rockets and motors. An educator had an Estes bulk pack that he didnt want anymore. My plan is to build three rockets from the set: a 2 x 18mm cluster model, a stretched rocket for staging, and this 3 x 18mm cluster. The bag of motors is just a bunch of A8-3s... so that explains why the cluster designs, I need to find a way to burn those up in bulk.
This rocket has four body tubes, three nose cones, and six fins. To ensure stability, I added a few grams of white glue to the nose cone. The last step will be adding a launch lug; probably a 3/16ths or if not, a 1/4th. CA glue was used for reinforcements, and white glue for the initial assembly. The central tube will eject a small parachute, the outer two (nacelles) will eject a streamer each. Perhaps a short delay on the outer two then a longer delay on the center would be a nice dual deploy of sorts.
