Problem
Helicopter has reduced fl ight
time or is underpowered
LED on receiver fl ashes
rapidly and aircraft will not
respond to transmitter (during
binding)
LED on the receiver fl ashes
rapidly and the helicopter will
not respond to the transmitter
(after binding)
Helicopter vibrates or shakes
in fl ight
Model does not hold level/
Panic recovery does not level.
Random movements in fl ight
Tail oscillation/wag or poor
performance
Drift in calm winds
Drift in wind
Severe vibration
Possible Cause
Flight battery charge is low
Flight battery is damaged
Flight conditions might be too cold
Transmitter too near aircraft during
binding process
Bind switch or button was not held
while transmitter was powered on
Aircraft or transmitter is too close to
large metal object, wireless source or
another transmitter
Less than a 5-second wait between
fi rst powering on the transmitter and
connecting the fl ight battery to the
helicopter
The helicopter is bound to a differ-
ent model memory (ModelMatch™
transmitters only)
Flight battery or transmitter battery
charge is too low
Aircraft or transmitter is too close to
large metal object, wireless source or
another transmitter
Damaged rotor blades, spindle, blade
grips, main gear teeth or cracked
main shaft.
Rotor head linkages not connected
correctly
Vibration
Loose tail boom, damaged tail rotor,
loose bolts, vibration
Vibration, damaged linkage, dam-
aged servo
Normal
Rotating component out of balance
Completely recharge the fl ight battery
Replace the fl ight battery and follow the fl ight battery
instructions
Make sure the battery is warm (room temperature) before use
Power off the transmitter. Move the transmitter a larger distance
from the aircraft. Disconnect and reconnect the fl ight battery to
the aircraft. Follow the binding instructions
Power off transmitter and repeat bind process
Move aircraft and transmitter to another
location and attempt binding again
Leave the transmitter powered on. Disconnect and reconnect
the fl ight battery to the helicopter
Select the correct model memory on the transmitter. Discon-
nect and reconnect the fl ight battery to the helicopter
Replace or recharge batteries
Move aircraft and transmitter to another
location and attempt connecting again
Check main rotor blades, blade grips, main gear and main
shaft for cracks, chips or missing teeth. Replace damaged
parts. Replace bent spindle
Connect the rotor head linkages to the short ball links on the
swashplate
Verify the receiver is properly attached to the helicopter. Verify
that no wires are contacting the receiver. Inspect and balance
all rotating components. Verify the main shaft and tail rotor
adapter are not damaged or bent. Inspect mechanics for
broken or damaged parts and replace as necessary
Verify that the boom is tight and completely inserted into the
frame. Inspect the tail rotor for damage. Verify the tail motor
mount is tight. Replace any damaged or worn components
Under normal operation the transmitter trims should not
require adjustment and the center positions are memorized
during initialization. If you fi nd that trim adjustments are
necessary after take off, verify the balance of all rotating
components, ensure the linkages are not damaged and make
sure the servos are in proper working condition. Perform the
Drift Calibration procedure
The model will drift with the wind but should remain level in
fl ight. Simply hold the cyclic stick in the necessary position
to keep the model stationary. The model must lean into the
wind to remain stationary, if the model remains level then it
will drift with the wind
Check the main shaft, tail rotor, main rotor blades, main
frame and adapter for damage, replace as necessary.
Vibration must be minimized for Panic Recovery and Return
to Level functions to work properly
