Required Hardware
This motor requires a L2 Certification to buy.
The J550ST-14 is designed to use the two-grain RMS-54/852 hardware and has a high-thrust pro le
for heavy rockets delivering 732 N-Sec (164.56 lb.-Sec.) of total impulse with a 1.31 second burn time
and an all-up weight in motor hardware of 1.82 lb. (828 g). It’s a great rocket motor for boosters and
heavy single-stage rockets for ights on small elds. This new core burner rocket motor utilizes
AeroTech's aerospace-grade Super Thunder™ (ST) propellant formulation with a burn rate midway
between Blue Thunder™ and Warp-9™ propellant types. The J550ST-14 generates a peak thrust of
649 N (145.9 lb.) with an average thrust of 557 N (125.21 lb.). The J550ST-14 includes an ejection
charge and produces tracking smoke via a 14 second time delay. We suggest electronic ejection
assist for longer or shorter time delays
