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-38/240 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: 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 Black Jack™ aerospace grade composite propellant formulation, which produces a visible black exhaust plume and a denser dark tracking smoke. Black Jack™ motors provide a higher level of thrust than White Lightning™ motors of the same total impulse and are perfect for high lift-off acceleration.

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 1 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 1 certification is received.

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