battery inserted.
No responseto controi input
Unable to bind to transmitter. Repeat the power up initializing
process. (Refer to P11:Binding
of radio transmitter and receiver)
2No response after
battery is connected
tn holinnnfar
l.Power lo transmitter and receiver.
2.Check transmitter and receiver voltage
3.Poor contact on battery terminals.
1.Turn on transmitter and ensure helicopter
battery is inserted properlv.
2.use fullv charoed batlerids.
3.Re-seafthe bätterv and ensure oood
contact between bätterv contacts:
3Motor does not
respond to throttle
stick,receiver LED
flashes. Helicopter battery depleted. Fully charge the battery, or replace
with a fully charged battery.
4Main rotor continue
to spin after landing Throttle trim accidentally
increased during flight Confirm throttle trim is in center or
slightly below.
5Motor fails to run,
but servo moves.
l.Throttle trim is too high, triggering safety
Drotection function. 2.Throttle was not all
the way down during power up. 3.Loose
motor connection or damaqed motor
l.Lower throttle trim and restart throttle.
2.Lower throttle stick all the way down and
restart throttle.
3.Re-seat the motor plug or replace the motor.
6Main rotor spins bul
unable to takeoff. l.Deformed main blades.
2. Helicopter battery depleted
l.Replace main blades
2.Charge or replace with a fully charged
battery
lStrong vibration
of helicopter
l.Deformed main blades
2.Bent main shaft
3.Deformed tail rotor
4.Over tightening of main blade grips.
l.Replace main blades
2.Replace main shaft
3.Replace tarl rotor
4.Re-tighten main blade grips with suitable
force.
8Tail siill off trim after
tab adjust ment, or
inconsistent speed
during lefvright pirouette.
l.Damaged tail rotors 2.Damaged tail
drive motor 3.Helicooter was not
stationary during power up. 4.Vibration
in duced gyro interference,causing tail

l.Replace tail rotors 2.Replace tail drive
motor 3.Re-oower the helicooter while
remaining stationary. 4.Refer to symptom 7

l.Elevator servo not level during
power up.
2.Elevatoer pushrod too long or
too short.
l.Center elevator trim after Dower uo.and
re-install elevator servo horn at lev'e'i

l.Aileron seryo not level during
power up.
2.Aileron pushrod too long or too
snon.
l.Center aileron trim after power up, and
re-install aileron servo hom at level position.
2.lf helicopter drifts left, adjust linkage longer
lf it drifts right,adjust linkage shorter.

2.control arm lock tight interference
1.confirm the body each agency and the
connecting rod head movement is smooth.
2.relax collar screw to control arm movement

voltage is low, the main rotor rotation
is too slow.
1, the confirmation of the main rotor head

Finished the above adjustments, still can not improve the situation, should immediately
stop flying and contact your dealer.
