F. For the booster stage the motor is

inserted so the motor extends out the back

3/8" (0.9 cm) and then held in place by wrap-

ping tape around the perimeter of the motor

and the tube.

G. The two stages are joined together by

inserting the upper stage motor (the portion

that sticks out) into the front of the booster

stage.

H. Insert and secure the engine igniter as

directed on the package the engines came

with.

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

engine 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 approaching 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 package and repeat the countdown and launch procedure.
