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-54/1706 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 (54FSD) 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 54mm Delay Drilling Tool (54RDDT), Not Included. The 54mm Delay Drilling Tool (54RDDT) is not yet available through this website. 

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.
