Fuselage Servo Replacement
Use the wing servo replacement instructions (1–9) to replace the rudder and/or elevator servos. Then plug the fuselage wire directly into the
receiver.
Wing Servo Installation
1. Plug the servo into the correctly marked aileron extension in the fuselage.
2. With the propeller removed, power ON the plane. Wait for the plane to initialize and for the servos to center.
3. Center the transmitter trims.
4. Align the servo arm by pressing the arm onto the servo. Install the servo arm screw, disconnect the servo from the aileron extension,
and begin the servo installation.
5. Using Deluxe Materials Foam 2 Foam (DLMAD34), secure the servo into the servo pocket.
6. Press the servo wire into the servo wire channel in the bottom of the wing.
7. Using Deluxe Materials Foam 2 Foam (DLMAD34), reinstall the foam servo wire retainer.
8. Reinstall the pushrod clevis into the aileron control horn.
TIP: Make sure the glue is dry!
9. Connect the aileron servo wires to the proper aileron extension wires in the fuselage.
10. Install the wing.
