AeroTech RMS K750ST-PS Rocket Motor Reload Kit New Product Information Release 7/11/22

AeroTech/Quest is pleased to announce the Tripoli certification and immediate availability of our new RMS Reloadable Motor System K750ST-PS rocket motor reload kit, AeroTech’s 2nd rocket motor reload kit designed to use the single-grain RMS-75/1280 hardware.

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.

  • Diameter: 75mm (2.95”)
  • Length: 266.7mm (10.5”)
  • Propellant: Super Thunder
  • Total Impulse: 1,298.7 N-Sec. (292.4 lb.-Sec.) Burn Time: 1.7 Seconds
  • Peak Thrust: 835.7 N (187.9 lb.) Delay Time: Plugged
  • Propellant Weight: 595 g (1.3 lb.) Loaded Weight: 1,947.5 g (4.3 lb.)

California State Fire Marshal classification and approval has been granted for the K750ST-PS RMS Reload Kit. It ships with a standard FirstFire Initiator, has a suggested retail price of $157.99 each and may be purchased by consumers 18 years of age or older with a minimum Level 2 NAR or TRA Certification, or by educational institutions, government agencies and licensed commercial entities.
