the motor hook holds it in place. 

     D. 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. 
Always use a launch pad that includes a blast 
deflector.

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 the 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 sys-

tem. The light (or buzzer) on the controller 
should come on.

Give a loud countdown 5 ... 4 ... 3 ... 2 ... 1 ... 
LAUNCH! 

Push and hold 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 mo-
tor 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.

Always follow the NAR* Model Rocket Safety Code when launching model 
rockets.
