1. RECOMMENDED MOTORS: Only use AEROTECH composite model
rocket motors when flying your AEROTECH rocket. See enclosed chart
for recommended motors and projected altitudes.
2. RECOVERY SYSTEM PREPARATION: Roll the parachute and shroud
lines, starting from the canopy peak, into a loose cylinder that will easily
slide into the lower body assembly body tube. Pack the long portion of the
shock cord into the body tube first. Next, insert the parachute. Finally,
insert the short length of shock cord into the body tube on top of the
parachute and put on the nose cone (or payload bay if your rocket has
one). Make sure that the parachute, shroud lines and shock cord are not
caught between the body tube and the shoulder of the nose cone or
payload bay. The nose cone or payload bay should slide freely. (NOTE:
Because your AEROTECH rocket has the LABYRINTH™ ejection gas
cooling system, no recovery wadding is required.)
3. MOTOR PREPARATION: The motors recommended for your AERO-
TECH rocket vary in physical size as well as performance. Your rocket
comes with a changeable motor adaptor and spacer tubes that permit the
the rocket to use each of the recommended motors without permanent
modification to the rocket.
Prepare your AEROTECH rocket motor according to the instructions that
come with the motor. Be sure the motor hook snaps in behind the nozzle
end of the motor and holds the motor securely in place. If the motor hook
does not hold the motor in place, bend the end of the hook until it does.
4. PRE-LAUNCH CHECKOUT: Before EVERY flight, perform a complete
pre-launch checkout of your rocket;
• Check that all fins and launch lugs are mounted securely and not
damaged.
• Examine the body tube, nose cone and payload bay to make sure
they are free of damage.
• Check that the shock cord is securely mounted to the ejection gas
baffle and nose cone (or payload bay bulkhead).
• Check that the parachute is securely tied to the shock cord.
• Check that the shock cord and parachute are free of any damage.
• See that the nose cone (or payload bay), packed parachute and
shock cord move freely. After awhile, an ejection charge residue
may build up at the top inside surface of the body tube. Wipe this
residue away with isopropyl ("rubbing") alcohol.
• With the tail of the rocket pointed down and the motor tube empty,
shake the rocket to remove any loose ejection charge debris left
from a previous flight. Periodically, fluff up the cooling mesh using
a bent wire inserted through the back end of the motor tube.
• Be certain the motor to be used is a recommended AEROTECH
model rocket motor and of a size appropriate for the launch area.
• Be sure the motor hook, motor adaptor and motor tube are not
damaged and hold the motor securely in place.
If the pre-launch checkout reveals any damage, repair the damage
before the rocket is flown again.

OPERATION INSTRUCTIONS
5. LAUNCH PAD: Your AEROTECH rocket must be flown from a launch pad
with a 1/4"(6.4mm) diameter metal launch rod at least 36"(0.9m) long (as
measured from the top of the blast deflector), such as the AEROTECH
MANTIS™ model rocket launch pad.
6. MOTOR IGNITION: Only launch your rocket using a remotely controlled
and electrically operated launch controller such as the AEROTECH®
INTERLOCK™ model rocket launch controller. Keep yourself and all
other people at least 30 feet (10 meters) away from the rocket during
launch.
7. LAUNCH AREA: Launch the rocket in a cleared outdoor area free of tall
trees, power lines and buildings. The side dimensions of the cleared area
should be at least one half of the projected altitude. An area for a radius
of at least 5 feet (1.5 meters) from the launcher should be clear of dry grass
or other flammable substances. Read and follow the Model Rocket Safety
Code of the National Association of Rocketry (NAR) and comply with all
federal, state and local laws in all activities with model rockets. A copy of
the NAR safety code is shown on the instructions that come with all
AEROTECH composite model rocket motors.
8. FLIGHT PROFILE: When the launch button of the electrical launch
controller is pressed, an electrical current causes the AEROTECH COP-
PERHEAD™ single lead igniter to ignite the composite propellant of the
AEROTECH rocket motor. The motor quickly builds up thrust and powers
your AEROTECH rocket into the air. During powered flight the rocket
increases in speed and altitude. When the propellant burns out the rocket
is moving at maximum velocity and a time delay material (delay grain)
inside the motor burns. While the delay grain burns the rocket coasts to
peak altitude at which point the delay grain ignites the ejection charge
within the forward part of the motor. The ignition of the ejection charge
creates a burst of hot expanding gas which is cooled by the permanent
metal mesh of the LABYRINTH™ ejection gas cooling system. The
cooled gas flows around the baffle, pressurizes the parachute bay and
ejects the nose cone (or payload bay) and parachute. The parachute then
deploys and gently returns the rocket to the ground where the rocket can
be prepared for another flight.
9. TRANSPORT AND STORAGE: To avoid damage to your AEROTECH
rocket during transport, pack it in a box surrounded by soft packing. Store
your rocket at room temperature.
