Problem
LED on the receiver fl ashes
rapidly and the helicopter
will not respond to the
transmitter (after binding).
The receiver LED may be
diffi cult to see within the
fuselage
Helicopter vibrates or
shakes in fl ight
Random movements in
fl ight
Tail oscillation/wag or poor
performance
Drift in calm winds
Drift in wind
Panic Recovery or Return
to Level does not level the
model
Severe vibration
Possible Cause
The bind plug was not removed
from the receiver after binding
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
different 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 or
blade grips
Vibration
Damaged tail rotor, main gear
mesh, loose bolts, vibration
Vibration, damaged linkage,
damaged servo
Normal
Model was not initialized on a
level, still surface
Model was not taken off of a level
surface
Battery strapped too tightly
to the model
Rotating component out of
balance
Disconnect the fl ight battery, remove the bind plug
from the receiver and reconnect the fl ight battery
Leave the transmitter powered on. Disconnect and
reconnect the fl ight battery to the helicopter
Select the correct model memory on the transmitter.
Disconnect 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 and blade grips for cracks or
chips. Replace damaged parts. Replace bent spindle
Verify the receiver is properly attached to the
helicopter. Inspect mounting tape for damage. 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
Inspect the tail rotor for damage. Verify that all bolts
on the tail assembly are properly tightened. Verify
main gear mesh and ensure no tight spots in the mesh
through full rotation. 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
The model will drift with the wind but should remain
level in fl ight. Simply hold the cyclic stick in the neces-
sary 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
Re-initialize the model on a level and still surface
Always lift off from a level surface
Loosen the battery strap
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
