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-98/7680 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 (98FSDSS) during assembly. Important: High Power RMS reload kits are not compatible with Mid Power RMS products.

The M4500ST-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 Super Thunder™ aerospace grade composite propellant formulation, which produces a bright violet-blue flame with a minimum of exhaust smoke. Super Thunder™ motors provide a higher ISP than Blue Thunder™.

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. Also, this motor requires U.S. State Department Licensing (SDL) for export (international shipments).

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

Richard Z. ★★★★★

Exactly what I needed for my high-power launch this weekend—the assembly was straightforward once I read the instructions, and the aluminum casing feels solid and well-machined. The reload fits perfectly in my RMS-98 hardware.

Mia ★★★★★

Finally scored a reload kit that fits my 98mm hardware perfectly. The kit slid together cleanly and the instructions were easy to follow. Got a great sustained burn right out of the box.

Brian H. ★★★★★

Just assembled the reload kit for the first time with the RMS-98/7680 hardware, and it fit together smoothly without any issues. The aluminum casing feels solid and well-machined, giving me confidence for the launch. Can't wait to see how this performs on the pad.
