Quick Answer
Assemble your AeroTech RMS-29/40-120 motor hardware by greasing the o-rings, installing the forward closure, loading the propellant, and securing the aft closure.
Why Proper Assembly Matters
Incorrect assembly can cause motor failure or damage to your rocket. The AeroTech RMS-29/40-120 hardware is reusable, so taking care during setup extends its life and ensures reliable performance.
Before You Start
Ensure the o-rings are clean and undamaged. Use only the included Super-Lube grease—other lubricants may damage the o-rings or cause seal failure.
Assembly Steps for AeroTech RMS-29/40-120 Motor Hardware
- Step 1: Grease the O-Rings: Apply a thin, even layer of Super-Lube grease to the o-rings on the forward and aft closures. This prevents tearing and ensures a good seal. Common mistake: applying too much grease can attract debris and cause seal failure.
- Step 2: Install the Forward Closure: Screw the forward closure into the aluminum motor case until it is snug. Do not overtighten—hand-tight is sufficient. Checkpoint: ensure the closure is fully seated but not cross-threaded.
- Step 3: Load the Propellant: Insert the reload kit's propellant grains and delay element into the motor case from the aft end. Follow the reload kit's instructions for proper orientation. Common mistake: inserting the delay element backward can cause early ejection.
- Step 4: Secure the Aft Closure: Screw the aft closure into the motor case, tightening it firmly. Ensure the nozzle is correctly aligned. Checkpoint: the closure should be snug but not forced—overtightening can damage the threads.
- Step 5: Final Check: Inspect the assembled motor for any gaps or misalignment. The closures should be flush with the case. If the motor does not fit smoothly into your rocket's motor mount, disassemble and check for debris or damaged o-rings.
