PRECAUTIONS
NAR Safety Code
NO DRY
GRASS
OR
WEEDS
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 NAR Safety Code.
MISFIRES
TAKE THE KEY OUT OF 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.
