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.

FINISHING YOUR ROCKET
Apply sanding sealer to fins. When sealer is dry, lightly sand parts.
Repeat sanding and sealing until balsa grain lines are filled. Optional:
Spray a light coat of automotive primer over entire rocket. Lightly sand
(600 grit) when primer is dry. This allows the paint to adhere better and
gives a smoother finish.
Spray paint the entire rocket gloss white. Follow instructions on spray
can for best results. Allow paint to dry overnight before applying decals.
Refer to photo on front of instructions and photo on panel for decal
placement. To apply decals, cut out each decal, dip in lukewarm water
for 20 seconds, and hold until it uncurls. Slip decal off backing sheets
and onto model. Blot away excess water. For a more realistic appearance
and to protect decals, spray a flat clear coat on the rocket.
