What are these different ypes of composite motors I hear about (White Lightning, Black Jack, Smokey Sam, etc.)?
These are all manufacturers’ names for various formulations of ‘stuff’ they have added to the propellants to get specific pyrotechnic effects. Black Jack (Aerotech): low(er) average thrust engine which produces a dense, dark exhaust to aid in tracking. Also has a distinctive roar. Note: BJ motors have a slow thrust buildup and long ignition time. Take care when using this type of motor in a cluster. Also play close attention to the manufacturer’s Maximum Recommended Liftoff Weight (MRLOW). Blue Thunder (Aerotech): high level average thrust engines with a bright violet-blue flame and very little visible exhaust. Designed for high thrust, high acceleration lift-offs. Ignites quickly. Very fast thrust build-up. Firestarter (US Rockets): low impulse composite formulation which produces large numbers of sparks. Hellfire (Vulcan): a high thrust motor which produces a bright red flame. Smokey Sam (Vulcan): produces a dark exhaust to aid in tracking. Silver Streak (Rocketflite/MRED): produces
