fireworks driven model rocket
thingiverse
I've designed this rocket for use with regular firework propellants. The engine should measure 21mm in diameter to fit neatly inside the tube. This design flies well when the center of gravity is set correctly. To make balancing easier, I've added a small notch where the rocket needs to be centered. You can suspend it from this spot using a string while attaching weights to the tip with glue.
