RMS-98 Rocket Motor Reload Kit

HIGH-POWER RMS™
Reloadable Motor System™
Rocket Motor Reload Kit
For RMS-98/2560-15360 Motor Hardware
DO NOT OPEN RELOAD KIT UNTIL READY TO USE
NOTE: This reload kit MUST be used with motor hardware, separately packaged propellant grains and motor liner tube specified below. RMS-98 reload kits do not include an ejection charge. RMS-98 motors must be used in conjunction with a timer, altimeter or radio-actuated recovery system.
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.
Motor Designation, Hardware and Typical Performance Data
RMS – RMS-98/2560-15360  Assembly Driawing and Instructions
NOTE: THE DRAWING SHOWN BELOW IS A GENERIC REPRESENTATION OF THE ACTUAL MOTOR. NOZZLE SIZE AND NUMBER AND DIMENSIONS OF PROPELLANT GRAINS MAY BE DIFFERENT.

Assembly Instructions (numbers refer to item number on drawing)

1. Lightly grease forward, aft and forward seal disk o-rings (3, 8 & 12) and case threads (5).

2. Assemble smoke grain (9) and smoke insulator (10) as shown.

3. Apply a layer of grease to one end of the smoke grain and then push step 2 smoke assembly into forward closure (11), greased end first.

4. Install forward seal disk o-ring (12) on groove in forward seal disk (7) and insert this assembly into one end of liner (4) until seated.

5. Insert propellant grains (6) into liner (4) with grain spacer o-rings if included (13) between each grain, then push liner assembly into case (5)
   until recessed equally from both ends of case. If supplied, position the grain marked “aft grain” at the aft/nozzle end of the case. NOTE: If supplied, follow the grain bonding instruction sheet for this step.

6. Install forward o-ring (8) into (forward) end of case (5) with the forward seal disk (7).

7. Thread forward closure (11) into the (forward) end of the case (5) with the forward o-ring (8) until seated.

8. Assemble nozzle (2), aft o-ring (3), and aft closure (1) into open (aft) end of case (5) until seated.

Before You Begin

• Do not modify the motor in any way.
• If any parts are missing or damaged, call AeroTech at 435-865-7100.
• Use only AeroTech RMS reload kits to refurbish an RMS motor.
• Do not interchange parts from different reload kits.
• Do not reuse any parts of the RMS reload kit.
• Save the reload kit plastic bag for the used reload kit parts. Dispose of bag and parts properly. Hardware and Supplies Required RMS 98mm aft closure
  RMS 98 case (see motor specification label for size) 98mm forward seal disk 98mm plugged forward closure -or98mm reload adapter  system (also refer toRAS instructions) Synco™ Super Lube™ or other grease Hobby knife Wet  wipesor damp paper towels

Preparation for Flight

1. Insert the coated end of a FirstFire™, Firestar™ or other initiator through the nozzle throat until it stops against the smoke charge grain.

2. Secure the initiator to the nozzle with a piece of masking tape.

3. 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.

4. Prepare the rocket’s recovery system and then launch the rocket in accordance with the Tripoli Rocketry Association (TRA) Safety Code and National
   Fire Protection Association (NFPA) Code 1127.

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 forward and aft closures.

2. Remove the smoke charge assembly components from the forward closure and discard. Using wet wipes or damp paper towels, remove all smoke charge and propellant residue from the closures.
   Post-Recovery Cleanup (cont’d)

3. Remove and discard the forward and aft o-rings from the motor case. Remove the liner, forward seal disk and nozzle from the casing by pushing on the nozzle end.
   Remove the forward seal disk from the liner, and remove and discard the forward seal disk o-ring. DO NOT
   DISCARD THE FORWARD SEAL DISK! Discard the nozzle and liner. Using wet wipes or damp paper towels, wipe the inside of the casing and the forward seal disk to remove all propellant residue.

4. 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
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. Metalstorm composite propellant consists primarily of Ammonium Perchlorate and a rubber-like plastic elastomer.
Disposal
Damaged or defective reload kits should be returned to RCS.
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.
Warranty
GENERAL: No warranty, either expressed or implied is made regard- ing AeroTech/RCS products, except for replacement or repair, at RCS’s option. Only those products which are proven to be defective in manufacture within 90 days or one year (applicable as described below), from the date of original purchase qualify.
