helicopter, then, the indicator light of the helicopter will keep flashing rapidly, set the helicopter
down to a platform.

2. Slide the power switch to “ON” position. To activate the remote controller, slowly push up the
throttle stick to the top and then push it down to the bottom. The indicator light flashes rapidly
while the remote controller is sending out connectional signal.

3. When the whole auto signal connection process is finished, both indicator lights of helicopter

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

Flight adjustment

1.Adjusting the swash plate
Insert the battery plug into the power socket of the helicopter and set the helicopter down to a
platform. When the transmitter and helicopter finish the auto signal connection process, the
indicator light will keep “ON” without blinking.Users can get a longer sound when the trimmer of
forward/backward is pushed to the middle position, at this time,please check the swash plate and
if it is not keep in horizontal, users can adjusting the length of the servo connector, until the swash
plate remains horizontal.
