Troubleshooting Guide
Problem Possible Cause Solution
Helicopter will not bind
to the transmitter
(during binding)
Low ight battery or transmitter
battery voltage
Fully charge or replace the ight battery and/or transmitter
batteries
Transmitter is not in bind mode
Power on the transmitter while holding the Trainer/Bind
switch. Hold the Trainer/Bind switch until binding is complete
Transmitter too close to the
helicopter during binding process
Power off the transmitter. Move the transmitter further away
from the helicopter.
Disconnect and reconnect the ight battery to the helicopter
and follow binding instructions
Helicopter will not link
to the transmitter
(after binding)
Helicopter is bound to a
different model memory
(ModelMatch
™
radios only)
Disconnect the ight battery. Select the correct model
memory on the transmitter. Reconnect the ight battery
Flight battery/Transmitter battery
charge is too low
Replace or recharge batteries
Flight controller will not
initialize
The helicopter was moved during
initialization
Lay the helicopter on its side during initialization if windy
The transmitter is powered off Power on the transmitter
Controls are not centered
Center elevator, aileron and rudder controls. Make sure the
throttle is at idle
Helicopter will not respond
to the throttle but responds
to other controls
Throttle not at idle and/or throttle
trim is too high
Lower the throttle stick and lower the throttle trim
The transmitter is not in normal
mode or throttle hold is on
Make sure the transmitter is in normal mode and throttle hold
is off
The motor is not connected to the
ESC or the motor wires are damaged
Connect the motor wires to the ESC and check motor wires
for damage
Flight battery charge is too low Replace or recharge ight battery
Throttle channel is reversed Reverse the throttle channel on the transmitter
Helicopter power is lacking
Flight battery has low voltage Fully charge the ight battery
Flight battery is old or damaged Replace the ight battery
Flight battery cells are unbalanced
Fully charge the ight battery, allowing the charger time to
balance the cells
Excessive current is being drawn
through the BEC
Check all servos and the helicopter motor for damage
Tail drive belt tension is not correct See "Tail Belt Tension" section in this manual
Helicopter will not lift off
Main rotor head is not spinning in
the correct direction
Make sure the main rotor head is spinning clockwise. Refer to
the motor control test
Transmitter settings are not correct Check throttle and pitch curve settings and pitch control direction
Flight battery has low voltage Fully charge the ight battery
Main rotor blades are installed
backwards
Install the main rotor blades with the thicker side as the
leading edge
The helicopter tail
spins out of control
Rudder control and/or sensor
direction reversed
Make sure the rudder control and the rudder sensor are
operating in the correct direction
Tail servo is damaged Check the rudder servo for damage and replace if necessary
Inadequate control arm throw
Check the rudder control arm for adequate travel and adjust
if necessary
Tail belt is too loose Make sure the tail drive belt tension is adjusted correctly
The helicopter wobbles
in ight
Cyclic gain is too high
Tuning options using forward programming are available
under the “Advanced Settings” section in this manual
Headspeed is too low
Increase the helicopter's head speed via your transmitter
settings and/or using a freshly charged ight pack
Dampers are worn Replace the main rotor head dampers
