How to charge the helicopter

The helicopter

split charging device

all-in-one charging device

To meet the different demands from different customers worldwide, two
different charging devices have been designed for charging. One is split
charging device (1 piece charger +1 piece charge controller), the other one
is all-in-one charging device (one charger only)The product is included with
either of the two charging devices. User should check the package to confirm
which charging device is included before reading the charging method.

How to charge the helicopter by all-in-one charging device.

Unplug the battery cable from the helicopter, then, insert the plug of the
battery cable into the port of the charger (matching the plug to the port)
to start charging.
Once charging is proceeding, red light is on. When charging is finished,
the red light will turn into green light.
Full charge takes about 2 hours.

How to charge the helicopter by split charging device.

Unplug the battery cable from the helicopter.
Insert the plug of the battery cable into the quadrate port of the charge
controller (matching the plug to the port)
Insert the plug of the charger cable into the circular port of the charge
controller, then, connect the plug of the charger to AC power outlet to
start charging.
Once charging is proceeding, the red power light of the charge controller
is on. When charging is finished, both the red light and green light of the
charge controller are on.
Full charge takes about 2 hours.

Turn on the remote control. To activate the remote controller,slowly push
up the throttle stick to the top and then push it down to the bottom. The
remote controller is activated once you hear a beep sound.Then, the
vindicator light flashes rapidly while the remote controller is sending out
connectional signal.

Connect the battery plug to the helicopter battery cable,the indicator light
of the helicopter will keep slowing flashing,set the helicopter down to a
platform. Once the helicoter receives the connecting signal,the indicator
light of the helicopter will keep flashing rapidly to check the gyro.

Preparation for flight

When the whole auto signal connection process is finished,both
indicatorlights of helicopter and transmitter are keep “ON” without
blinking,then push up the throttle stick slowly and the helicopter takes off.

1.User may push either of the control sticks to skip the auto signal connection
process once the helicopter finished signal connection.

2.Set the connection one by one. Otherwise, it may not be connected.

3.Once the transmitter is turned off, the connection procedure must be repeated
to operate the helicopter.

4.Please pull out the battery plug from the helicopter battery socket.

OPERATIONAL TIPS

Check and regulate the swashplate of the helicopter

The swashplate of the helicopter should be kept horizontal, otherwise, the helicopter will fly
forward/backward/leftward/rightward automatically even though no control signal is given.
Hence, it is very important to check andconfirm that the swashplate is horizontal before flying
the helicopter. To get the swashplate horizontal, there are two ways available for regulation.

7

A.When the helicopter is hovering but still
keeping flying forward automatically,
please take out the elevator servo
connecting bar, then, clockwise rotate
the bar for one circle(360°). How many
circle should be regulated will depend
on the tilt angle of the swashplate.
Generally, rotate the bar for one or two
circles for one regulation.(Pic 11)
B.When the helicopter is hovering but still
keeping flying backward automatically,
please take out the elevator servo
connecting bar, then, counter-clock wise
rotate the bar for one circle (360°). How
many circle should be regulated will
depend on the tilt angle of the swashplate.
Generally, rotate the bar for one or two
circles for one regulation. (Pic 11)
C.When the helicopter is hovering but still
keeping flying leftward automatically,
please take out the aileron servo connecting bar, then,
clockwise rotate the bar for one circle(360°). How many
circle should be regulate, will depend on the tilt angle of the swashplate.
Generally, rotate the bar for one or two circles for one regulation.(Pic 12)

(1) If the swashplate is slightly inclined, it is okay to regulate the trimmer
button of the remote control to get the swashplate retain horizontal.
(2) If the swashplate is greatly inclined, then, it should be better to
regulate the length of the servo connecting bar to get the swashplate
parallel to the ground. The operation instruction are specific as follow:

Parallel

swashplate

D.When the helicopter is hovering but still keeping flying rightward
automatically, please take out the aileron servo connecting bar , then,
counter-clock wise rotate the bar for one circle(360°). How many circle
should be regulate, will depend on the tilt angle of the swashplate.
Generally, rotate the bar for one or two circles for one regulation. (Pic 12)

Trimmer Functions

If the helicopter keeps moving forward/backward even there is no control
signal given, users may adjust the elevator trim to keep the helicopter balanced.

STICK MOD 1 or 2:

If the helicopter keeps moving
leftward, turn right of Trimmer C
until it gains balance.

STICK MOD 1 or 3:

If the helicopter keeps moving
backward, push up Trimmer A
until it gains balance.

If the helicopter keeps moving
forward, push down Trimmer A
until it gains balance.

STICK MOD 2 or 4:

If the helicopter keeps moving
backward, push up Trimmer D
until it gains balance.

If the helicopter keeps moving
forward, push down Trimmer D
until it gains balance.

If the helicopter keeps moving leftward/rightward even there is no control
signal given, users may adjust the aileron trim to keep the helicopter balanced.

STICK MOD 3 or 4:

If the helicopter keeps moving
leftward, turn right of Trimmer B
until it gains balance.

If the helicopter keeps moving
righttward, turn left of Trimmer B
until it gains balance.

9

STICK MOD 1 or 2:

STICK MOD 3 or 4:

If the helicopter keeps spinning even there is no control signal given,
users may adjust the rudder trim to keep the helicopter balanced.

If the helicopter keeps spinning
clockwise in the air,turn right of
Trimmer B until it gains balance.

If the helicopter keeps spinning
counter-clockwise in the air,turn
left of Trimmer B until it gains
balance.

If the helicopter keeps spinning
clockwise in the air,turn right of
Trimmer C until it gains balance.

If the helicopter keeps moving
righttward, turn left of Trimmer C
until it gains balance.

Operating

Upward

Push up the throttle control stick, the
rotation speed of the mains rotors are
increasing and the helicopter ascends
accordingly.

Downward

Push down the throttle control stick,
the rotation speed of the mains rotors
are decreasing and the helicopter
