The AeroTech Reloadable Motor System RMS is an aluminum cased reusable motor in kit form that is assembled by the user. You will need AeroTech RMS-54/1706 motor hardware to build and complete the motor for many reliable flights. Motor hardware is available separately in a complete set, and also as individual parts. This motor requires installing a forward seal disc (54FSD) during assembly. Important: High Power RMS reload kits are not compatible with Mid Power RMS products. You will need to set the desired delay time using the 54mm Delay Drilling Tool (54RDDT), Not Included. The 54mm Delay Drilling Tool (54RDDT) is available in the AeroTech Accessories section of this website. 

This RMS motor reload utilizes RCSs exclusive White Lightning™ aerospace grade composite propellant formulation, which produces a gorgeous bright white flame with lots of dense white smoke and a throaty roar at lift-off.

The AeroTech motor reload kit comes with 1 rocket motor reload. Reload kits include all internal motor components and FirstFire™ Initiators. Requires HAZMAT shipping via UPS or FEDEX. The sale of this high power motor to persons under 18 years of age is currently prohibited by federal law. This is a High-Power motor requiring Level 2 High-Power certification through NAR or Tripoli to purchase. Orders containing this item will not be shipped until proof of age (such as a copy of a driver’s license) and proof of Level 2 certification is received.

Certified by the Tripoli Rocketry Association (TRA), the National Association of Rocketry (NAR) and the Canadian Association of Rocketry (CAR).

Leo M. ★★★★★

First flight with this reload kit and the burn was impressively consistent from ignition to burnout, no chuffing or pressure spikes at all. The aluminum case threaded together cleanly with the RMS hardware and the delay grain fit snug without any extra sanding. Getting those three distinct ejection

Owen E. ★★★★★

The fit into the 54/1706 hardware was snug but easy after the first assembly, and the propellant grains slid in cleanly with no shaving needed. Fire it once and you'll see why the reloadable route pays off—this pack delivered exactly the burn I expected.

Carter N. ★★★★★

Assembled this reload kit with the RMS-54/1706 hardware and the fit was perfect, no filing or forcing needed. Everything you need for the motor comes packed in there, and the burn was clean with a solid, predictable flight. Feels good knowing I can reuse the aluminum case for the next one.
