Troubleshooting
Unit does not operate
1. Transmitter "AA"batteries are depleted
or installed incorrectly as indicated by a
dim or unlit LED on the transmitter or the
low battery alarm
2. No electrical connection
3. Flight battery is not charged
4. Crash has damaged the radio inside
the
fuselage
1. Check polarity installation or replace with
fresh “AA” batteries
2. Push connectors together until they click
3. Fully charge the battery
4. Replace the fuselage or receiver
Aircraft keeps turning in
one direction
1. Rudder or rudder trim is not adjusted
correctly
2. Wing is not centered over the fuselage
1. Adjust stick trim lever or adjust rudder
position (see page 14)
2. Center the wing
Aircraft is difficult
to control
1. Wing or tail is damaged
1. Replace damaged part
Aircraft keeps pitching
up steeply
1. Wind is too gusty or strong
2. Elevator is trimmed 'up' too much
1. Postpone flying until the wind calms down
2. Adjust elevator trim 'down'
Aircraft won't climb
1. Battery is not fully charged
2. Elevator may be trimmed 'down'
1. Charge battery fully shortly before flying
2. Adjust elevator trim 'up' (see page 14)
PROBLEM
POSSIBLE CAUSE
SOLUTION

1. Don’t fl y in winds over 7 mph (11 K/h).
First-time pilots should get help from
an experienced radio control pilot
during
fi rst fl ights.
2. Choose your fl ying fi eld carefully–
grass and soft ground with a 600-foot
(183-meter) diameter of open space
is optimal for fl ying and will lengthen
the life of the Super Cub. Make sure
there are no obstacles that will get
in your way when fl ying, such as trees
or buildings. Make sure you do not fl y
where there are pedestrians who
could be hurt by the airplane.
3. Remember that holding the stick full
over for too long can cause the
airplane to spiral dive and crash.
At the very fi rst sign of the Super Cub
beginning to spiral down, immediately
release the stick and give the
opposite turn control to the spiral,
then pull back on the elevator gently
to level fl ight and level the wings.
4. Don’t attempt to fl y or do maneuvers
beyond your fl ying abilities without
seeking the assistance of an experi-
enced
pilot.
5. If you’re gliding with the motor off,
allow the Super Cub more area for
turns.
6. Position yourself at your fl ying fi eld
to keep the sun at your back and out
of your eyes. Wear sunglasses on
bright
days.
7. Keep the Super Cub upwind, espe-
cially on windier days, to prevent it
from
“fl ying away.” The wind is
normally stronger at higher altitudes
than it is on the ground.
8. Keep your plane in front of you so
you don’t have to turn in circles as
you
fl y. Try to avoid fl ying directly
overhead.
