Troubleshooting Guide
Problem
Possible Cause
Solution
Helicopter will not initialize
Throttle at high position
Reset controls with throttle stick and throttle
trim at center or lowest setting
Switches not in normal position
Set flight mode to OFF/0 and exit throttle hold
Pitch or throttle servo reversing im-
properly configured
Reset servo reversing
Refer to “Programming your Transmitter”
Helicopter will not spool up
Throttle hold on
Turn off HOLD with throttle low and trim
centered or low.
Refer to “Throttle Hold”
Low battery voltage
Completely recharge flight battery
Motor power decreases
during flight
Receiver uses default soft Low Voltage
Cutoff (LVC)
Recharge flight battery or replace battery that
is no longer performing
Cannot turn off throttle hold
Stunt Mode switch still on
Set flight mode to OFF/ 0 and exit throttle hold
Throttle not at low position
Reset controls with throttle stick and throttle
trim at center or lowest setting
Powers off when flying
upside down (inverted)
Stunt Mode off
When flying, switch stunt mode to ON/1 before
flying inverted
Will not bind properly to
non-computer radio
Helicopter binds differently to non-
computer radios
Release bind button/ switch after applying left
rudder. Do not hold the bind button/ switch
after applying left rudder
Poor tail authority
Tail boom is cracked
Replace tail boom
The tail rotor blade is warped or bent
Twist rotor blade back into position or replace
Climb out rate is greatly
reduced
Main gear has slipped on the main
shaft
Push main gear back into position
LED on receiver flashes
rapidly and aircraft will not
bind to transmitter (during
binding)
Transmitter is too near aircraft during
binding process
Power off transmitter, move transmitter a larger
distance from aircraft, disconnect and recon-
nect flight battery to aircraft and follow 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 receiver flashes
rapidly and aircraft will not
respond to transmitter (after
binding)
Less than a 5-second wait between
first powering on transmitter and con-
necting flight battery to aircraft
Leaving transmitter on, disconnect and recon-
nect flight battery to aircraft
Aircraft is bound to a different model
memory (
ModelMatch
TM
radios only)
Select correct model memory on transmitter
and disconnect and reconnect flight battery to
aircraft
Flight battery/transmitter battery
charge is too low
Replace/recharge batteries
Transmitter may have been bound to
a different model (or with a different
DSM
Protocol)
Select the right transmitter or bind to the new
one
Aircraft or transmitter is too close to
large metal object, wireless source or
another transmitter
Move aircraft and transmitter to another loca-
tion and attempt connecting again
Helicopter vibrates or
shakes in flight
Damaged rotor blades, spindle or blade
grips
Check main rotor blades and blade grips for
cracks or chips. Replace damaged parts. Re-
place bent spindle
