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 your 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.
