(1) Adjust the bellcrank of servo. Disconnect the power cable of helicopter first and then turn off transmitter. Unscrew
the screw in the bellcrank of servo and take off the bellcrank. Re-turn on transmitter and re-connect the power
cable of helicopter in sequence. After servos’ initialization, re-mount the bellcrank of servo and make sure the
angle is 90 between bellcrank and ball linkage of servo, and then tighten the screw of bellcrank.
(2) Adjust the ball linkage of servo. Make the swashplate parallel to the horizontal level via adjusting the length
