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-75/3840 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 stainless steel forward seal disc (75FSDSS) during assembly. Important: High Power RMS reload kits are not compatible with Mid Power RMS products.

The L1940X-PS is a Plugged/Smoke motor reload. Plugged reload kits do not utilize a motor-actuated delay or ejection charge. Plugged motors must be used in conjunction with a timer, altimeter or radio-activated recovery system.

This RMS motor reload utilizes RCSs exclusive Propellant X™ aerospace grade composite propellant formulation, which is a high ISP propellant, and produces a bright white flame with a moderate amount of smoke.

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).

Customer Reviews (4.8 / 5 · 4 reviews)

Emma G. ★★★★★

Right on the money for myL3 flight—the reload slipped together cleanly and the delay grains were spot on. No fiddling during assembly, and the thrust curve felt exactly as advertised.

Amelia ★★★★★

Flew this reload in my L3 cert bird and the aluminum casing held up perfectly with no signs of wear. It packed a solid burn and the delay was spot on for my 4-inch rocket.

Natalie A. ★★★★★

Assembling this reload kit took about 20 minutes with the included instructions, and the aluminum casing fit my existing hardware perfectly with no fiddling. The propellant grains slid in clean and the O-rings sealed tight on the first flight, which gave me a solid, consistent burn every time.
