Problem
Possible Cause
Solution
Model does not
hold level/Panic
recovery does not
level. Random
movements in
fl ight
Vibration
Verify the receiver is properly attached
to the helicopter. Verify that no wires are
contacting the receiver. Inspect and bal-
ance 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
Tail oscillation/
wag or poor
performance
Loose tail boom,
damaged tail rotor,
loose bolts, vibration
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
Drift in calm winds
Vibration, damaged
linkage, damaged servo
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
Drift in wind
Normal
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 station-
ary, if the model remains level then it will
drift with the wind
Severe vibration
Rotating component out
of balance
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
Helicopter will
not enter drift
calibration
Incorrect fl ight mode
selected
Set the fl ight mode to Stability, low angle
