Package Contents
Aerospike RMS-Plus reload kit components
Complete reload delay kit
Igniter & ejection charge kit
Hardware and Supplies Required
RMS 54mm standard aft closure
RMS 54mm case (see RMS-Plus packaging tube label
for size)
RMS 54mm standard forward closure OR 54mm reload
adapter system (if needed; refer to RAS instructions)
54mm forward seal disk
54mm RMS delay drilling tool (54mm RDDT)
Synco™ Super Lube™ or other grease
Hobby knife or scissors
Wet wipes or damp paper towels
Preparation for Flight
1. Remove the supplied FirstFire™ igniter from the
cardboard tube and straighten the leads.
2. Strip 1/2"-1" of insulation from the end of the leads.
3. Remove the aft closure, aft O-ring and both parts of
the Aerospike nozzle from the motor.
4. Insert the black-coated end of the igniter completely
into the motor core, until the coated end is touching the
time delay element in the forward closure.
5. Replace the Aerospike nozzle components, threading
the igniter leads through one of the annular openings in
the nozzle. Reinstall the aft O-ring and aft closure and
firmly tighten the closure.
6. Install the motor into the rocket's motor mount tube.
Ensure that the motor is securely retained in the rocket
by using positive mechanical means to prevent it from
being ejected during recovery system deployment.
7. Prepare the rocket's recovery system and then
launch the rocket in accordance with the National
Association of Rocketry (NAR) and/or Tripoli Rocketry
Association (TRA) Safety Codes.
Post-Recovery Cleanup
NOTE: Perform motor clean-up as soon as possible
after motor firing. Propellant and smoke charge residues
become difficult to remove after 24 hours and can lead
to corrosion of the metal parts. Place the spent motor
components in the reload kit plastic bag and dispose of
properly.
1. After the motor has cooled down, unthread and
remove the aft and forward closures.

Post-Recovery Cleanup (cont'd)
2. Remove the spent components from the casing by
pushing on the nozzle end and discard. Using wet wipes
or damp paper towels, wipe the inside of the casing and
all surfaces of the aft and forward closures and forward
seal disk to remove all propellant residue. DO NOT
DISCARD THE FORWARD SEAL DISK!
3. Apply a light coat of grease to all threads and the
inside of the motor case. Reassemble metal parts and
store motor in a dry place.
First Aid
Do not ignite an AeroTech motor indoors. Do not breath
fumes from the rocket motor exhaust. For a minor burn,
apply a burn ointment. For a severe burn, immerse the
burned area in ice water at once and see a physician as
quickly as possible. In the unlikely event of oral ingestion
of the propellant, induce vomiting and see a physician
as quickly as possible. The composite propellant used in
AeroTech reload kits consists primarily of Ammonium
Perchlorate and a rubber-like plastic elastomer.
Redline™ propellant also contains Strontium Nitrate,
and Mojave Green™ propellant contains Barium Nitrate.
Disposal
Pack assembled motor firmly in a hole in the ground so
that only the nozzle is exposed, away from people,
animals, buildings and flammable materials. Ignite motor
electrically from a distance of 30 feet or more.
Propellant, delay and ejection charge (if installed) will
burn until consumed. Wait until the motor has cooled off
before disassembly and cleanup.
Fire Safety
Tests show that the pyrotechnic components of RMS™
reload kits will not explode in fires and normally will not
ignite unless subjected to direct flame and then will burn
slowly. Use water to fight any fires in which AeroTech
RMS™ reload kit pyrotechnic components may become
involved: Direct the water at the AeroTech RMS™ reload
kit pyrotechnic components to keep them below their
550 deg. F autoignition temperature. Foam and carbon
dioxide fire extinguishers will NOT extinguish burning
propellants of the type used in RMS™ reload kit
pyrotechnic components. Keep reload kit pyrotechnic
components away from flames, sources of heat and
flammable materials.

RMS-PLUS™ HIGH-POWER
Reloadable Motor System™
Aerospike™ Rocket Motor Reload Kit With
RMS-Plus Delay Assembly & Operation Instructions
For RMS-54/852-1706 Motor Hardware
DO NOT OPEN RELOAD KIT UNTIL READY TO USE
Note: Motor designation and complete performance specifications (including
sample time-thrust curve) are printed on the RMS-Plus packaging tube.
WARNING-FLAMMABLE: READ INSTRUCTIONS BEFORE USE. Use RMS
reload kits only in accordance with instructions. Sale to persons under 18 years
of age prohibited by federal law. For use only by certified users 18 years of age
or older. Ignite by electrical means only. Do not smoke when loading RMS motors
or use in the vicinity of open flames. CAUTION: Keep out of reach of children.
Metalstorm™ propellants produce showers of hot sparks. Clear launch area of all
combustible material for at least a 75 foot diameter radius around launcher.
Follow NAR & TRA safety codes at all times. Motor hot after firing.
Setting the Time Delay
Note: If you want to use the longest (as-supplied) time
delay, do not use the RMS delay drilling tool and instead
proceed with general motor assembly (inside pages).
1. WARNING: Do not smoke and ensure that there are
no open flames or heat sources nearby when setting the
time delay. Assemble the AeroTech 54mm RMS delay
drilling tool with the desired amount of delay time
removal (i.e., the - 4 or - 8 seconds removal marked on
the tool label) facing the exposed drill bit and delay grain.
2. Optional: Place the washer between the drill knob
and the tool if you want to remove 2 seconds less than
the value printed on the tool (i.e., - 2 or - 6 seconds
removal).
3. Place the delay grain into the cavity in the appropriate
end of the tool, hold the tool and grain firmly together and
turn the drill knob several times clockwise until the drill
knob sits flush against the drill tool body.
4. Remove the tool and shake out the shavings from the
tool and delay grain. Dispose of the shavings by burning
with a safe method and in a safe location.
