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 Mojave Green™ aerospace grade composite propellant formulation, which produces a brilliant green exhaust plume with a moderate amount of smoke. Mojave Green™ motors high density and specific impulse delivers a higher total impulse in each motor size than any other AeroTech propellant.

The AeroTech motor reload kit comes with 1 rocket motor reload. Reload kits include all internal motor components and FirstFire™ Initiators. This AeroTech motor is U.S. mailable with no hazmat fee!

Emma H. ★★★★★

Finally got around to assembling this reload kit and the aluminum casing fit together perfectly with my existing hardware. It was straightforward to pack the propellant grains and the seal discs lined up exactly as expected. Definitely adds some nice variety to my mid-power launches without needing

Edward X. ★★★★★

Flew this reload on a sunny weekend and the delay grain was perfectly timed. The assembly process felt straightforward once I had the casing ready, and the thrust curve on the 29mm case gave a nice, steady boost. Definitely a solid value for the price per flight.

Sophia O. ★★★★★

Just got my first reload kit for the 29/40-120 casing, and it’s rewarding to see the motor come together once you follow the instructions. The aluminum casing feels solid enough to handle multiple flights, so I’m curious how many reloads it will actually last.
