Hey Everyone! Here is the new Hermes rocket motor! It uses black powder salvaged from a D-12 rocket motor. Then, use a mortar and pestle to grind it up. The finer the better!!! You can also use a G-25W re-loadable fuel grain that will work even better. It works by igniting the black powder, then that creates a ton of pressure that flies out the converging - diverging nozzle to make thrust. To build the motor you need the 3d printable motor case, nozzle, fuel grain, optional o-ring, M3.5 screws.
