Real servo position
Real servo position is the relation of differential rotation speed outputted by
motor to keep aircraft stable during flight.
Tips:
User can judge the balance of motors and propellers by observing the real servo
position in level flying.
Example: when clockwise and anticlockwise propellers lose balance(suppose
clockwise motor is not leveling, the reaction torque generated by which is
smaller than that generated by anticlockwise motor), when in level flight and
heading unchangeable, the real rudder position will keep stable with left to 5~7.
With the same pulse width output, the reaction torque generated by clockwise
motor is smaller than that generated by anticlockwise in the same rotation
speed, which lead aircraft rotate to the right, autopilot will output levorotation
torque automatically, namely the differential make the clockwise rotation speed
faster and anticlockwise slower. In this condition, aircraft can fly normally and
do not need hover any more, but the power consumption and temperature of
clockwise motor are higher than the anticlockwise motor’s.
So, it is suggested that user need to precisely detect the balance and level
symmetry of motor and propeller to get a more stable flight. Until level flight
and hovering, the rudder of real servo position will be smaller (1~2) or around
neutral position.

When get 5 or more GPS satellites locks, switch CH5 to position 3 and CH6 to
position 1, that is the flight status is “auto-hovering”, then push the throttle
stick after moving rod in V shaped, when throttle stick is more than half, aircraft
will take off automatically and auto-hover about 2~3 meters from the ground
and getting into auto-hovering status.
