❏ Install the tail rotor servo into the mechanics and connect the
servo to the gyro. Remove the servo arm screw from the servo.
Turn the receiver power on and allow the gyro to initialize.
Enter programming mode and go to parameter 3 – Servo Limits
[Red, Three Flashes]. While in the servo limits parameter the
servo will remain centered.
90˚
❏ Place an appropriate servo arm onto the servo and ensure that it
is perpendicular to the tail rotor pushrod as shown. Remove the
unused sides of the servo arm.
❏ Install the control ball supplied with your helicopter onto the
servo arm. For smaller electric helicopters (250, 300, 450
and 500 size) we recommend placing the ball 7.5mm from
center. For larger electric models or nitro powered models we
recommend placing the ball 13.5mm from center. Once the
control ball has been installed place the arm back onto the servo
ensuring that it is perpendicular to the tail rotor pushrod. Install
the servo arm screw.
