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-29/40-120 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. Important: Mid Power RMS reload kits are not compatible with High Power RMS products. 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.  The sale of this high power motor to persons under 18 years of age is currently prohibited by federal law. Orders containing this item will not be shipped until proof of age (such as a copy of a driver’s license) is received.

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

Amelia ★★★★★

Fired this motor for the first time last weekend, and the aluminum casing felt incredibly solid compared to the single-use motors I've used before. The thrust curve was exactly as advertised, giving my rocket a nice steady boost off the pad.

Ryan ★★★★★

I love how straightforward this reload kit is to assemble once you've got the hardware—the aluminum casing slides together cleanly every time. The delay granules packed in there gave me a perfect 4-second coast on my last flight.

Charlotte ★★★★☆

Assembling the kit took a bit of patience since it's all user-built, but the aluminum casing feels solid once it's together. The reload fits the 29/40-120 hardware perfectly, so no fiddling with adapters. Just wish the instructions had a few more diagrams for first-timers.
