Troubleshooting Guide
Problem
Possible Cause
Solution
Helicopter control response is
inconsistent or requires extra
trim to neutralize movement
Aircraft was not initialized properly
or a vibration is interfering with the
sensor operation
Disconnect the fl ight battery, center the control trim and
re-initialize the helicopter
Helicopter will not respond
to throttle
Throttle too high and/or throttle trim
is too high
Disconnect the fl ight battery, place the throttle stick in the
lowest position and lower the throttle trim a few clicks. Con-
nect the fl ight battery and allow the model to initialize
Helicopter moved during initialization
Disconnect the flight battery and re-initialize the helicopter
while keeping the helicopter from moving
Helicopter has reduced fl ight
time or is underpowered
Flight battery charge is low
Completely recharge the fl ight battery
Flight battery is damaged
Replace the fl ight battery and follow the fl ight battery instruc-
tions
Flight conditions might be too cold
Make sure the battery is warm (room temperature) before
use
LED on receiver fl ashes
rapidly and aircraft will not
respond to transmitter (during
binding)
Transmitter too near aircraft during
binding process
Power off the transmitter. Move the transmitter a larger dis-
tance from the aircraft. Disconnect and reconnect the fl ight
battery to the aircraft. Follow the binding instructions
Bind switch or button was not held
while transmitter was powered on
Power off transmitter and repeat bind process
Aircraft or transmitter is too close to
large metal object, wireless source or
another transmitter
Move aircraft and transmitter to another
location and attempt binding again
LED on the receiver fl ashes
rapidly and the helicopter will
not respond to the transmitter
(after binding)
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 differ-
ent model memory (ModelMatch™
transmitters only)
Select the correct model memory on the transmitter. Discon-
nect 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 com-
ponents. 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 boom supports, 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 sup-
port 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
