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

The L850W-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 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. 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).

Samuel ★★★★★

Assembling the aluminum case was straightforward once I got the hang of it, and the fit of the reload kit into the hardware was snug with zero wobble. Burned through my first flight and the casing held up perfectly for a quick reload.

Ruby E. ★★★★★

First time using a 75mm reload and the assembly was surprisingly straightforward with the included instructions. The burn was clean and consistent, and the nozzle held up perfectly through the entire thrust curve. Definitely getting another pack for my next launch.

Andrew B. ★★★★★

Really impressive how smoothly the reload kit fits into the 75/3840 hardware without any forcing. The aluminum casing feels solid and I've already assembled two motors without any issues. If you already have the required hardware, this is a perfect way to keep launching.
