Welcome to The RCS Store
Serving Research & Professional Rocketry Since 1995
9/3/14 Delay and Smoke Grains Available
Vacuum mixed and cast 0.610" O.D. and 0.933" O.D. delay and smoke grains are perfect for use with our Experimental Motor Kits™ (EMKs) or combined with our individual matching motor parts in a motor of your own design.
10/2/13 Bulk AP Now Available
We now have standard grade rotary rounded 200 micron Ammonium Perchlorate (AP) w/TCP available in bulk (shipping and hazmat charges apply). Price is $4.99 per pound, minimum order quantity is 250 lbs. Please contact RCS for details and to place an order.
10/2/13 Thrust Rings Added to Store
29 and 38mm thrust rings for single use motors added to the store under a new "Thrust Rings" category.
9/25/13 Propellant Grains Added to Store
Pre-cast lengths of White Lightning™, Black Jack™ and Blue Thunder™ propellant fitting our 29 & 38mm EMKs have been added to the store under the "Propellant Grains" category. Full ballistic data is provided for tailoring your motor operating characteristics in BurnSim or other internal ballistics simulation software.
7/25/13 Shipping Update
We've made some changes to the store so that postage is calculated more accurately depending on what is ordered and we don't have to process shipping refunds.
5/13/13 High Power EMKs Being Added to Store
We have decided to add a complete line of high power Experimental Motor Kits (EMKs) to the RCS store, ranging in size from from 29/60 to 98/15360. They will be added as time permits, over a several week period. Check the EMK category for regular updates.

- Standard grade rotary rounded 200 micron Ammonium Perchlorate (AP) w/TCP in bulk (shipping and hazmat charges apply). Price listed is per pound, minimum order quantity is 250 lbs. Please contact RCS for details and to place an order.$4.99
- Standard grade rotary rounded 200 micron AP w/TCP (hazmat charges apply). 20 pound pail.$129.99
- Copper Chromite is a proprietary blend of copper and chromium oxides, black in color, and is a moderate burn rate catalyst which finds use in endburning and medium-to-high burn rate compositions. Typical concentration level is 0.5 - 3.0% of propellant weight. 100 gram jar.$19.95
- Desmodur E 744 Isocyanate is an excellent room temperature curative for HTPB. It provides plenty of pot life and good physical properties. If you've been using PAPI or Isonate 143-L you'll be amazed at the difference! Use at the 13.1% concentration level with R-45HTLO with an OH value of .85 (hydroxyl equivalent weight of 1176.5). For the mathematically...$13.75
- In our opinion, Isodecyl Pelargonate (IDP) is the best plasticizer for HTPB-based binders. Its low density, low viscosity, low vapor pressure and cure retardant properties will give you a noticeable improvement over DOA, DBP or whatever else you've been using. 10-35% of the total binder percentage is the usual concentration. 8 ounce bottle.$13.75
- R-45HTLO polybutadiene resin premixed with 0.95% CAO-5 antioxidant and 2.38% HX-752 bonding agent. This premix should be used for propellants that contain 400 micron or larger Ammonium Perchlorate, or whenever maximum propellant strength is desired. HX-752 is unique among the commonly-used bonding agents in that it does not release Ammonia during propellant...$62.45
- We've chosen to offer R-45HTLO instead of R-45M for a number of reasons. It has a slightly higher functionality, which results in a higher crosslink density with the better room temperature curatives (like E 744 described below), without resorting to other ingredients that can adversely affect the cure chemistry. It also allows you to use higher percentages...$62.45
