My son launched this just-released G75-10M in his epoxy-reinforced Aerotech Initiator, a fine test vehicle for new propellants.
The propellant has titanium sponge mixed in for a dramatic sparky effect (here’s a primer on propellants that I wrote for scienceblogs).
Unlike the Skidmark motors, these new Metalstorms have white smoke, and so I plan to try a few at the Dairyaire night launch. They also seem to pack more Newton-seconds, which is surprising given the energy penalty for the pyrotechnics (the G75 and G80 both have 120 N-sec). Will move up to the H, J and K sizes next.
Here is a short video of this launch. The Initiator went much higher than we expected.
