Preparation for flight

gyro,then,push up the throttle stick slowly to takes off the helicopter.
If the helicopter is flying slightly to one side, please use the trimmer

button to tune it to balance.

Check and regulate the swashplate of the helicopter

(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:

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 and
confirm 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 10)
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 10)
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 11)
D.When the helicopter is hovering but still keeping flying rightward
automatically, please take out the aileron servo connecting bar , then,
counter-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 11)
