inserting the upper stage motor (the portion

that sticks out) into the front of the booster

stage.

I. Insert and secure the engine igniter as

directed on the package the engines came

Countdown and Launch Procedure

Fly your rocket on a large field that isn't

near any power lines, trees, or low flying

aircraft. The larger the field, the greater

your chances of recovering your rocket. The

launch area around the pad must be free of

dry weeds and brown grass. Launch only

during calm weather with very little or no

wind and good visibility.

10. Remove the safety key from the

launch controller.

9. Slide the launch lugs over the launch

rod to place the rocket on the pad. The

rocket should slide freely over the rod.

8. Attach the micro-clips to the igniter.

The clips must not touch each other or the

metal blast deflector.

7. Stand back from your rocket as far as

the launch wire allows (at least 5 meters - 15

feet).

6. Insert the safety key to arm the launch

system. The light (or buzzer) on the control-

ler should come on.

Give a loud countdown 5 ... 4 ... 3 ... 2 ...

1 ... LAUNCH!

Push and hold the the button until the en-

gine ignites. Then remove the safety key and

place the safety cap on the launch rod.

Misfire Procedure

Occasionally the igniter will burn, but the motor will fail to ignite. If this

happens, the cause is that the pyrogen on the igniter was not in contact

with the engines propellant. When an ignition failure occurs, remove the

safety key from the launch controller and wait 60 seconds before ap-

proaching the rocket. Remove the old igniter from the engine and install

a new one. Make sure that the igniter is insert fully into the engine and

touches the propellant. Secure the igniter as directed on the engine pack-

age and repeat the countdown and launch procedure.
