9/13/17 98mm Crossload™ O-ring Kit Now Available

8/2/17 98mm Single-Use 3-Grain EMK and 3-Grain 98mm Fiberglass Casing Added to Store
A 98mm single-use 3-grain Experimental Motor Kit (EMK) is now available under the "Experimental Motor Kits" category, and a 98mm 3-grain fiberglass casing is available under the "Fiberglass Motor Casings" category.

5/4/17 Asphalt Based Thermoplastic Composite Solid Rocket Propellants Book Released
This publication by Chuck Piper documents the manufacture and use of Asphalt/Perchlorate propellants in military, commercial, and small-scale experimental rocket motor applications.

10/5/16 Low cost initiator from Triton Space Technologies Introduced
The low cost initiator is perfect for "head-end" upper stage ignition, clusters and "instant on" ignition of any motor.

9/29/16 3D Printed Plastic Thrust Rings Added
3D printed plastic thrust rings to fit 29, 38 and 54mm single use casings are now available under the "Thrust Rings" category.

9/29/16 Low Molecular Weight Hydroxyl-terminated Polybutadiene Resin Now Available
RCS low molecular weight Hydroxyl-terminated Polybutadiene (HTPB) resin has an unusually low viscosity as a result of a molecular weight of only 1,300. Its corresponding low equivalent weight naturally allows the use of a higher percentage of isocyanate, which results in a substantially reduced premix viscosity. In addition, lower plasticizer percentages can be employed to increase propellant toughness, while maintaining processability. OH values are typically 1.80 (equivalent weight 556); the measured value is printed on the container label. Sold in 1 gallon and 1/2 gallon bottles.

7/20/16 New Restrictions on AP Purchases
Due to increased Department of Homeland Security (DHS) concerns, we we are placing new restrictions on all Ammonium Perchlorate (AP) purchases. Effective immediately, all purchasers of AP must have a Tripoli Rocketry Association (TRA) L2 or higher certification on file with RCS, or provide evidence that they are a legitimate business or academic customer.
