Parabellum Rocket -- spins in flight, looks like a TOW missile

thingiverse

Initially constructed traditionally, it eventually disintegrated due to wear and tear. The replacement model V2 is made entirely of plastic. By printing it with 0.3mm resolution at a 50% infill rate, you can create an impressive rocket. This design features slightly inclined fins for an initial angle of attack. After accelerating past the launch rail, the rocket will start spinning. V1 performed flawlessly, and V2 is expected to do so as well. If interested, I can produce kits at a small fee upon request. An update from November 25th, 2013 details some improvements made. The original rocket weighed 6.7oz, exceeding the maximum takeoff weight for a C6-5 engine (4oz max). To accommodate this, an extension was added to mount a D engine with a maximum lift capacity of 14oz, preserving the CG and enhancing the rocket's resemblance to a TOW. The engine mount has a slot for the engine hook, ensuring the weight stays within the flight envelope. However, be advised that it will have quite a powerful launch. Additionally, rails were added to offer external support to the joined tubes using strong CA glue and ground plastic filler. After filing, any gaps are undetectable, and the rocket looks fantastic when painted. Enjoy its flight in the sky! For assembly, place a raft or 'mouse ears' about 2mm high to support the fin parts during printing. This tip is particularly relevant for FDM printers over STL printers or sintering processes.
