Problem
Helicopter has
reduced fl ight time
or is underpowered
LED on the fl ight control
board fl ashes rapidly and
aircraft will not respond to
transmitter (during binding)
LED on the fl ight control
board fl ashes rapidly and
the helicopter will not
respond to the transmitter
(after binding)
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
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
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, tailboom, main
gear mesh, main shaft, 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
Main shaft cracked
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.
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
and balance all rotating components. Verify the main shaft
and tail rotor are not damaged or bent. Inspect mechanics for
broken or damaged parts and replace as necessary
Inspect the tail rotor for damage. Inspect the tail boom and
main shaft for cracks. Verify main gear mesh and ensure no
tight spots in the mesh through full rotation. Replace any dam-
aged 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 necessary posi-
tion 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
Check the main shaft for cracks and replace if necessary
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
