Problem
LED on receiver ashes
rapidly and aircraft will
not respond to transmitter
(during binding)
LED on the receiver ashes
rapidly and the helicopter
will not respond to the
transmitter (after binding)
Helicopter vibrates or shakes
in ight
Model does not hold level/
Panic recovery does not
level. Random movements
in ight
Tail oscillation/wag or poor
performance
Drift in calm winds
Drift in wind
Severe vibration

Possible Cause
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
rst powering on the transmitter
and connecting the ight battery to
the helicopter
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,
damaged servo
Normal
Rotating component out of balance
Power off the transmitter. Move the transmitter a larger
distance from the aircraft. Disconnect and reconnect the
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 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
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 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
