PRECAUTIONS
PRE-LAUNCH CHECK For safety, never launch a damaged rocket. Check the
rocket’s body, nose cone and fins. Also, check the engine mount, recovery
system and launch lug(s).
Repair any damage before launching the rocket.
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 starter clips and remove the engine. Take the plug and starter out of the engine. If the starter has burned, it worked but did not ignite the engine because it was not touching the propellant inside the engine. Put a new starter all the way inside the engine without bending it. Push the plug in place. Repeat the steps under Countdown and Launch.
