The Rocketry Show

Jeff Kodysz was a very talented rocketeer. His talents stretched from 3D printing, Lazer Etching, and he had a knack with making logos. He created the current logo for The Rocketry Show that you look at everytime you visit our website or listen to one of our episodes.

Jeff passed away a few weeks ago after a short battle with illnesses. He will be missed by his friends, family, and us.

We are all glad to have known him.

CG stops by to give a quick update on technical changes some of you may have noticed, and what that means.

The team talk about Narcon 2023, and we review this year’s calendar of big launch events so far…

In the first episode of Season 9, we talk to Joe Pfeiffer of the Open rocket team, diving a bit deeper into the program’s features, and some use case items for advanced and High power rocketry.

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
