1. Caution: Always launch the airplane away from people and obstacles. It is important to adjust or “trim” your ducted fan airplane
for proper flight.
2. Select an open area to test your plane.
3. With the motor off, grasp the airplane fuselage and gently toss the plane into the wind. It
should glide straight ahead and settle gently to the ground. See the diagram below.
A = Dive. Bend elevators upward slightly.
B = Stall and crash. Bend elevators down slightly.
C = Correct flight path.
D = To turn left, bend the rudder to the left slightly.
E = To turn right, bend the rudder to the right slightly.
4. If needed, using a hobby knife, carefully cut along the
indentations on the side of the elevators and top and bottom
of the rudder. See the drawings.
5. Repeat steps 3 & 4 until your plane glides well.
SAFETY RULES
• ALWAYS LAUNCH THE AIRPLANE AWAY
FROM PEOPLE AND OBSTACLES
• NEVER POINT THE AIRPLANE AT
ANYONE OR ANYTHING
• ALWAYS LAUNCH SKYWARD
• DO NOT LAUNCH INDOORS
1. Choose an open field, free of trees, power
lines and other obstacles. Hold the airplane in
your hand over your head and switch on the
motor with your other hand. Toss the airplane
into the wind, keeping the wing level.
2. The airplane should climb gently and turn
gradually. If it stalls and crashes, adjust the
elevator. If it does not turn, bend the rudder
slightly to the left or right. Refer to “TRIMMING
YOUR ELECTRIC FREE-FLIGHT DUCTED FAN
AIRPLANE” for details.
IMPORTANT THINGS TO REMEMBER
WHEN YOU ARE FLYING YOUR FREE-
FLIGHT DUCTED FAN AIRPLANE
The most important thing that determines how
well your airplane flies is how well you have
trimmed it.
Because it can fly high and far you must be in a
large area away from houses, streets, trees and
overhead wires.
Closely inspect your airplane after every flight.
Make sure the wing is not broken and that they
are securely attached to the fuselage.
Make sure the tail parts are not cracked or
broken. See the repair section for details.
Always throw the electric free-flight airplane
into the wind. Do not fly the airplane if it is
to windy.
Never charge your batteries for more than 60
seconds. If you do, you may overheat the
batteries in the airplane or your charger and
damage them.
REPAIR: If the fuselage is cracked or
damaged, apply white glue and cellophane
tape and let dry overnight.
WARNING: Do not use super glue. It will
damage the foam. If the wing or tail becomes
damaged, apply cellophane tape over the
damaged area.
