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

The M2050X-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 3 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 3 certification is received.

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

Hazel M. ★★★★★

The 75mm reload kit is a solid choice for high-power flights, and I was impressed by how cleanly the propellant grains fit into the casing. It took about 20 minutes to assemble everything, and the burn was perfectly consistent. Just make sure you have the right hardware case ready to go.

Matthew ★★★★★

Assembling the aluminum casing for the first time felt solid, and the reload kit packed everything I needed for a smooth launch on a calm day. The 5120 size fits the hardware perfectly, and the burn was steady with a strong, reliable thrust.

Thomas F. ★★★★★

Putting the aluminum casing together was straightforward and the manual is clear enough for a first-timer. The burn was impressively clean, and the rocket tracked perfectly straight on the rail. Definitely worth the time it takes to assemble.
