Tube Launch Model Rocket

This is a experimental rocket designed to launch out of a 3 inch tube. It is still heavily in development and not for flight. The design was based off of the Javelin Missile. The rocket is fully 3d printed. The fins pop out via springs or rubber bands and work really well. It has a piston ejection system built in the parachute bay. It can also be extended with a coupler to carry a significantly large payload. I still got a lot of tweaks I must do to get this rocket flying! If you have a any name
