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. 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.
