FLYING YOUR ROCKET
Choose a large field (500 ft. [152 m] square) free of dry weeds and brown grass. The
larger the launch area, the better the chance of recovering your rocket. Football fields
and playgrounds are great. Launch only with little or no wind and good visibility.
Always follow the National Association of Rocketry (NAR) Safety Code.
MISFIRES
TAKE THE KEY OUT OF THE CONTROLLER. WAIT ONE MINUTE
BEFORE GOING NEAR THE ROCKET! Disconnect the igniter clips and remove the
engine. Take the plug and igniter out of the engine. If the igniter has burned, it worked
but did not ignite the engine because it was not touching the propellant inside the
engine. Put a new igniter all the way inside the engine without bending it. Push the plug
in place. Repeat the steps under Countdown and Launch.
