Assembly and Operation Instructions Assembly and Operation Instructions
READ THIS BEFORE YOU BEGIN:
• Study the illustrations and sequence of assembly. THE SEQUENCE OF ASSEMBLY IS
EXTREMELY IMPORTANT. READ ALL INSTRUCTIONS BEFORE USE. USE RMS™
MOTORS AND RELOAD KITS ONLY IN ACCORDANCE WITH ALL INSTRUCTIONS.
Review the parts list and become familiar with all parts before assembly. IF ANY PARTS
ARE MISSING OR DAMAGED, CONTACT RCS AT 1-435-865-7100 or email at
warranty@aerotech-rocketry.com.
• DO NOT USE ANY PARTS OF THE RMS™ SYSTEM THAT ARE DAMAGED IN ANY
WAY . If in doubt, contact RCS at the number above for assistance.
• DO NOT MODIFY THE MOTOR IN ANY WAY . Modification of the motor or the reload
kit parts could result in motor failure, lead to the destruction of both your rocket and motor
and may cause personal injury, death and/or property damage. Modification of the motor
or reload kit in any way will invalidate your motor warranty.
• USE ONLY AEROTECH/RCS RMS™ RELOAD KITS AND MOTOR PARTS TO
REFURBISH YOUR RMS™ MOTOR . The AeroTech/RCS reload kits have been
designed specifically for use in your particular AeroTech/RCS RMS™ motor. Use of
imitation components may destroy your motor, rocket and payload and will invalidate
your motor warranty. Only use AeroTech/RCS RMS™ reload kits intended for your
specific AeroTech/RCS RMS™ motor. DO NOT INTERCHANGE PARTS! Do not use
AeroTech/RCS RMS™ reload kits or motor components for any other purpose than to
refurbish an AeroTech/RCS RMS™ motor.
• DO NOT REUSE ANY OF THE DISPOSABLE PARTS OF THE RMS™ RELOAD KIT .
This includes the liner, nozzle and o-rings. These components have been designed for
one use only and must be discarded after firing. Reuse can result in motor failure during
subsequent operation and will invalidate your motor warranty.
• Motors are hot after firing. Although the RMS™ operates at a lower temperature than
most disposable motors, the higher thermal conductivity of the aluminum motor parts
may make it seem otherwise. If necessary to handle a motor before it has cooled down,
use a rag or similar article.
• Read and follow the safety code of the Tripoli Rocketry Association (TRA) and comply
with all federal, state and local laws in all activities involving high power rockets.

Chapter 1. Forward Closure Assembly

1-1. Fig.-1: Apply a light coat of Synco™ Super Lube™ or
other grease to all threads, sealing surfaces and o-
rings. This will facilitate assembly and prevents the
threads from seizing.
1-2. Fig.-2: Insert the smoke charge element into the smoke
charge insulator until it is flush with both ends of the
insulator.
1-3. Fig.-2: Apply a liberal amount of grease to one end of
the smoke charge element and the outside of the smoke
charge insulator.
1-4. Fig.-3: Insert the greased end of the smoke charge
assembly into the smoke charge cavity of the forward
closure until it is seated against the forward end of the
cavity. Set the completed forward closure assembly
aside.
Chapter 2. Liner & Case Assembly
2-1. Fig.-4: Dispense approximately 20 grams of 15 or 30
minute epoxy and mix thoroughly.
2-2. Fig.-5: Apply epoxy to one end of the 1 st (aft chamfered)
& 2 nd grains. NOTE: The chamfered end of the 1
faces the nozzle and is not coated with epoxy.
DO NOT OPEN RELOAD KIT UNTIL READY TO USE.
