Motor Casing Parts

For rocketeers who build and customize their reloadable motor setups, motor hardware components provide the essential parts needed for proper assembly, retention, and performance tuning. Whether you're looking for replacement parts, upgrades, or expanded functionality, we offer a full range of AeroTech RMS and RMS-Plus components for mid-power, high-power, and electronic deployment systems.

Types of Motor Hardware Components

Nozzles & Closures – Precision-machined aft and forward closures, along with high-temperature composite nozzles, designed to handle intense heat and pressure for reliable motor operation.

Reload Adapter Sets & Spacers – Used to adjust motor configurations, these allow rocketeers to modify case sizes and adapt different reloads within compatible RMS motor hardware.

EFC (Electronic Forward Closures) – RMS-Plus Technology – A timer-based electronic recovery system that attaches to the forward end of AeroTech RMS motors, allowing precise ejection charge control without the need for electric matches.

Motor Retention & Sealing Components – O-rings, forward seal discs, and retaining rings to ensure a secure, gas-tight seal within the motor casing.

Three RMS Product Lines 

RMS Mid-Power Components – Designed for all RMS mid-power reloadable motors, offering easy-to-use hardware for hobbyists transitioning from single-use motors.

RMS High-Power Components – Built for RMS high-power reloads, providing robust closures, nozzles, and adapters for high-performance flights and certification launches.

RMS-Plus Components (EFC Motor Closures) – A cross-compatible system for both mid-power and high-power motors, allowing electronic recovery deployment with timed ejection charges.

Important: Standard RMS Mid-Power and RMS High-Power components are NOT cross-compatible, but RMS-Plus EFC Closures can be used with either system, depending on the closure selected.
