1/16" Vent Hole

4-1. Fig.-12: Insert the black coated end of the Copperhead igniterthrough the nozzle throat and into the slot or core in thepropellant grain(s) until it stops against the delay element.

4-2. Fig.-12: Using scissors of a hobby knife, cut a corner off theclosed end of the nozzle cap to create a vent hole about 1/16"wide. Push the nozzle cap over the nozzle to hold the igniterin place.

4-3. Install the RMS motor into the rocket's motor mount tube.Ensure that the motor is securely retained in the rocket byusing positive mechanical means to prevent it from beingejected at the time of ejection charge firing. If using a motorhook, be sure to hold the hook away from the motor duringinsertion into the motor tube to prevent the hook from scrapingthe motor casing. Position the hook tab into the slotted recessin the aft closure.

4-4. Prepare the rocket's recovery system and then launch therocket in accordance with the National Association of Rock-etry (NAR) Safety Code and National Fire Protection Associa-tion (NFPA) Code 1122. NOTE: It is strongly recommendedthat you use the AeroTech Interlock™ igniter clip with Cop-perhead igniters. Tests have shown that nearly 100% ignitionreliability is achieved with an Interlock clip used in conjunctionwith a properly-installed Copperhead igniter and a fully-charged 12-volt car battery.

4-5. If a misfire occurs and a loaded AeroTech/RCS RMS motordoes not ignite for any reason within five seconds of pressingthe launch button, release the launch button and remove thesafety key from the electrical launch controller. WAIT ONEMINUTE before approaching or allowing anyone else toapproach the rocket. Keep your fingers and hands out fromunderneath the rocket and away from the possible path of theexhaust jet. DO NOT place any part of your body over thelaunch pad. Disconnect the clip from the Copperhead igniter.Carefully remove the rocket from the launch pad. Keeping themotor nozzle pointed away from your face and body - andaway from any other person's face or body - remove the redplastic nozzle cap and repeat the motor preparation andlaunching process.

Chapter 5. Post-Recovery Cleanup

NOTE: Perform RMS motor cleanup as soon as possible after motorfiring. Propellant and delay residues become difficult to remove 24hours after motor firing. These residues can lead to corrosion of metalparts. DISPOSE OF SPENT MOTOR COMPONENTS PROPERLY.

5-1. After the motor has cooled down, remove the forward and aftclosures. Remove and discard the delay insulator and delayo-ring from the forward closure. Using wet wipes or damppaper towels, remove all propellant, delay and ejection chargeresidues from the closures. WARNING: FAILURE TO RE-

MOVE DELAY RESIDUE FROM THE INSIDE OF THE FOR-WARD CLOSURE CAN LEAD TO GAS LEAKAGE AROUNDTHE DELAY O-RING ON A SUBSEQUENT FLIGHT ANDDAMAGE TO YOUR RMS FORWARD CLOSURE ANDROCKET VEHICLE.

5-2. Remove the nozzle, liner assembly and forward and aft o-ringsfrom the case and discard. Using wet wipes or damp papertowels, wipe the inside of the case to remove all propellantresidue.

5-3. Apply a light coat of grease to all threads and the inside of themotor case. Reassemble parts and store in a dry place.

Chapter 6. First Aid

For a minor burn, apply a burn ointment. For a severe burn, immerse theburned area in ice water at once and see a physician as quickly aspossible. In the unlikely event of oral ingestion of the propellant, inducevomiting and see a physician as quickly as possible. The AeroTech/RCS composite propellant consists primarily of ammonium perchlorateand a rubber-like plastic elastomer.

Chapter 7. Disposal

Damaged or defective RMS reload kits should be returned to RCS.

Chapter 8. Fire Safety

Tests show that the pyrotechnic components of RMS reload kits willnot explode in fires and normally will not ignite unless subjected todirect flame and then will burn slowly. Use water to fight any fires inwhich AeroTech/RCS RMS reload kit pyrotechnic components may be-come involved: Direct the water at the AeroTech/RCS RMS reload kitpyrotechnic components to keep them below their 550 deg. F autoigni-tion temperature. Foam and carbon dioxide fire extinguishers will NOTextinguish burning propellants of the type used in RMS reload kit pyro-technic components. Keep reload kit pyrotechnic components awayfrom flames, sources of heat and flammable materials.
