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
[email protected].
•
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.
Apply a light coat of Synco™ Super Lube™ or other
grease to all threads and both o-rings. This will facilitate
assembly and prevents the threads from seizing.
1-2.
Fig.-1:
Insert the smoke charge insulator into the smoke
charge cavity until it is seated against the forward end
of the cavity.
1-3.
Fig.-2:
Apply a liberal amount of grease to one end of
the smoke charge element. Insert the
greased
end of
the smoke charge element into the smoke charge
insulator until it is seated against the forward end of the
smoke charge cavity. Set the completed forward clo-
sure assembly aside.
2-1.
Fig.-3:
Using a hobby knife or similar tool, carefully
deburr (chamfer) both inside edges of the liner tube (3-
5/8” O.D. black plastic tube).

Fig.-4:
Place the greased forward seal disk (3/32" thick
X 3-3/8" O.D.) o-ring into the groove in the forward seal
disk.
2-3.
Fig.-5
:::::
Insert the smaller (o-ring) end of the seal disk
into the open end of the liner tube until the seal disk
flange is seated against the end of the liner.
2-4.
Fig.-6:
Perform the remaining assembly steps with the
liner held in a horizontal position. Install the propellant
grains into the liner, seated against the forward seal
disk.
NOTE:
Three propellant grains are shown in all
illustrations. RMS-98/10240 motors use four (4) grains.
2-5.
Fig.-7:
Push the liner assembly into the motor case aft
(nozzle) end first until it is equally recessed from both
ends of the case.
NOTE:
A coating of grease on the
outside surface of the liner will facilitate installation and
casing cleanup after motor firing.
2-6.
Fig.-8:
Place the greased forward (3/16" thick X 3-5/8"
O.D.) o-ring into the forward (bulkhead) end of the case
until it is seated against the forward seal disk.
2-7.
Fig.-9:
Thread the forward closure assembly into the
forward end of the motor case by hand until it is seated
against the case.
2-8.
Fig.-10:
Insert the nozzle into the aft end of the motor
case, with the nozzle flange seated against the liner
assembly.
2-9.
Fig.-11:
Place the greased aft (3/16" thick X 3-5/8"
O.D.) o-ring into the groove in the nozzle.
2-10.
Fig.-12:
Thread the aft closure into the aft end of the
motor case by hand until it is seated against the case.
NOTE:
There will be considerable resistance to thread-
ing in the closure during the last 1/8" to 3/16" of travel.
It is normal if a slight (1/16” to 3/32”) gap remains
between the closure and the case and the grains rattle
slightly in the liner after tightening.
