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-38/720 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 38mm Forward Seal Disc during assembly. Important: High Power RMS reload kits are not compatible with Mid Power RMS products. You will need to set the desired delay time using the 18-38mm Delay Drilling Tool (RDDT), Not Included. The 18-38mm Delay Drilling Tool (RDDT) is available in the AeroTech Accessories section of this website.

This RMS motor reload utilizes RCSs exclusive Metalstorm™ aerospace grade composite propellant formulation. Metalstorm™ is a sparky propellant, lights easily and produces a large brilliant white exhaust plume, a long yellow-orange dense spark trail, and plentiful white sparks that fan out in flight. As with all rocket motors using spark-generating propellants, special precautions must be taken to avoid fires around the launch pad by clearing the immediate area of all combustible materials in accordance with applicable fire and safety codes.

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 (4.8 / 5 · 5 reviews)

Julian V. ★★★★★

Snapped right into my RMS-38/720 hardware with no trimming or fiddling, and the grains seated cleanly on the first try. The delay grain gave a nice steady build instead of the hard kick I was bracing for.

David D. ★★★★★

First time using a reload kit instead of a single-use motor and the assembly was way simpler than I expected. The grains fit snug into the 38/720 hardware with no trimming needed, and the delay element was spot on. Burn was clean and consistent all the way through.

Ellie U. ★★★★★

The aluminum casing feels really solid when you're assembling it, and the kit fit together cleanly with no burs or frustration. I grabbed this for my RMS-38/720 hardware and it was exactly what I needed to get flying again.
