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-75/2560 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 K780R-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.

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

Customer Reviews (5.0 / 5 · 4 reviews)

Ava V. ★★★★★

First flight with this reload kit was smooth as butter—the grains slid right into the case with no binding, and the delay grain fit snugly. Burned clean and left barely any residue to wipe out afterward.

Thomas K. ★★★★★

The aluminum casing fit perfectly into my existing hardware, and the propellant grains aligned smoothly without any extra sanding needed. Burned consistently through the full thrust curve, exactly what I expected for this impulse class.

Sebastian S. ★★★★★

This reload kit went together cleanly with the hardware I already had; the propellant grain fit snugly and the delay grains were clearly marked, which made assembly straightforward. For the price, it’s a solid option to get another flight out of your case without buying a whole new motor.
