Perfect for heavy rockets launched from small fields, the K750ST-PS delivers 1,298.7 N-Sec (292.0 lb.- Sec.) of total impulse with a 1.74 burn time and an all-up weight in motor hardware of 4.29 lb. (1,945.9 g). It’s also a great booster for two-stage rockets, and features AeroTech’s aerospace-grade Super Thunder (ST) propellant formulation with a burn rate midway between Blue Thunder and Warp-9 propellant types. The K750ST-PS generates a peak thrust of 835.7 N (187.9 lb.) with an average thrust of 746.6 N (167.9 lb.). Super Thunder propellant displays a bright blue flame with prominent Mach diamonds and little smoke.  Although the K750ST-PS produces tracking smoke, it is a “plugged” motor that does not include an ejection charge and requires the utilization of an electronically-activated recovery system.
