Problem
Possible Cause
Solution
LED on the receiver fl ashes
rapidly and the helicopter
will not respond to the
transmitter (after binding)
The bind plug was not removed
from the receiver after binding
Disconnect the fl ight battery, remove the bind plug
from the receiver and reconnect the fl ight battery.
Less than a 5-second wait
between fi rst powering on the
transmitter and connecting the
fl ight battery to the helicopter
Leave the transmitter powered on. Disconnect and
reconnect the fl ight battery to the helicopter
The helicopter is bound to a
different model memory
(ModelMatch™ transmitters only)
Select the correct model memory on the transmitter.
Disconnect and reconnect the fl ight battery to the
helicopter
Flight battery or transmitter
battery charge is too low
Replace or recharge batteries
Aircraft or transmitter is too close
to large metal object, wireless
source or another transmitter
Move aircraft and transmitter to another
location and attempt connecting again
Helicopter vibrates or
shakes in fl ight
Damaged rotor blades, spindle or
blade grips
Check main rotor blades and blade grips for cracks or
chips. Replace damaged parts. Replace bent spindle
Random movements in
fl ight
Vibration
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
Tail oscillation/wag or poor
performance
Damaged tail rotor, main gear
mesh, loose bolts, vibration
Verify that the boom support bolts are tight and the
plastic boom support ends are properly adhered to the
boom support rods. 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
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.
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 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.
Panic Recovery or Return
to Level does not level the
model
Model was not initialized on a
level, still surface
Re-initialize the model on a level and still surface.
Model was not taken off of a level
surface
Always lift off from a level surface.
Severe vibration
Battery strapped too tightly
to the model
Loosen the battery strap
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.
