Troubleshooting Guide
Problem
Helicopter control
response is inconsistent
or requires extra trim to
neutralize movement
Helicopter will not
respond to throttle
Helicopter has reduced
flight time or is
underpowered
LED on receiver flashes
rapidly and aircraft
will not respond to
transmitter (during
binding)
LED on the receiver
flashes rapidly and
the helicopter will
not respond to the
transmitter (after binding)
Helicopter vibrates or
shakes in flight
Random movements
in flight

Possible Cause
Aircraft was not initialized properly or a
vibration is interfering with the sensor
operation
Throttle too high and/or throttle trim
is too high
Helicopter moved during initialization
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
The bind plug was not removed from
the receiver after binding
Less than a 5-second wait
between first powering on the trans-
mitter and connecting the flight 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
Disconnect the flight battery, center the control trim and
re-initialize the helicopter
Disconnect the flight battery, place the throttle stick in the
lowest position and move the throttle trim to the center
position. Connect the flight battery and allow the model
to initialize
Disconnect the flight battery and re-initialize the helicop-
ter while keeping the helicopter from moving
Completely recharge the flight battery
Replace the flight battery and follow the flight 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
flight 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
Disconnect the flight battery, remove the bind plug from
the receiver and reconnect the flight battery.
Leave the transmitter powered on. Disconnect and recon-
nect the flight battery to the helicopter
Select the correct model memory on the transmitter. Dis-
connect and reconnect the flight 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 ro-
tor adapter are not damaged or bent. Inspect mechanics
for broken or damaged parts and replace as necessary
