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-75/5120 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 (75FSD) during assembly. Important: High Power RMS reload kits are not compatible with Mid Power RMS products.

The L1420R-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 Redline™ aerospace grade composite propellant formulation, which produces a visible scarlet flame. Redline™ motors burning rate lies midway between that of White Lightning™ and Blue Thunder™. Photos don’t do justice to the “laser-beam” intensity and color of Redline™…. you have to see it to appreciate it!

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. Also, this motor requires U.S. State Department Licensing (SDL) for export (international shipments).

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 I. ★★★★★

The aluminum casing felt solid in my hands, and the assembly instructions were clear enough for a first-timer with reloads. It took about 20 minutes to put together, and the burn was smooth on launch.

Matthew ★★★★★

This is my first time putting together a reloadable motor and the assembly instructions were surprisingly clear despite the complexity. The grains slid into the casing perfectly and I'm excited to fly it this weekend.

Eva U. ★★★★★

The aluminum casing feels rock solid in my hands, and the fact that it’s reusable makes the price sting a lot less. Assembling it took some patience, but once it was together, the fit was perfect against the hardware.
