F Setting the Tail Sensor Direction
1. Move the helicopter nose to the right. The tail rotor blades will move in the same direction as left
rudder input. If the tail rotor blades move in the wrong direction, reverse the sensor direction.
2. Move the rudder stick once in any direction. The Status LED will change color.

G Adjusting the Swashplate Servo Centering
Menu Point G electronically adjusts the center point of the cyclic servos.
With all swashplate servos connected, the servos are now operating in their mechanical center
position or "reference position." The Status LED is OFF.
1. Install the servo horns on the servos so the horns form an angle close to 90° with the
linkage rod. The angle will not be a perfect 90°.
2. Move the rudder stick once to select a servo.

3. Move the elevator stick forward and back to adjust the center position.
4. Move the rudder stick to select the next servo. Complete Steps 2 and 3 for each servo.
IMPORTANT: Menu Point G does not have a time limit.
NOTICE: You can switch between the servo trimmings as often as you like. Note that
only the servo positions you see when trimming is active are important. So even if the
servo horns are perfectly aligned at Status-LED off, you have to check and adjust the
center positions. Status-LED off has no further functionality despite from finding the
true center position of the servo for installing the servo horn. It will neither affect your
servo trimming nor will these positions be used later.
5. While one servo is still selected adjust the cyclic/
swashplate linkage, adjust the cyclic/swashplate
linkage rods according to your helicopter manual. The
swashplate should be centered and the main blades
should have 0° of pitch. Always make rod length
adjustments from the bottom (servos) to the top (blade
grips).
6. Press the setup button to save the selection and move to
Menu Point H.
