Wing Servo Removal
1. Remove the propeller.
2. Remove the wing.
3. Unplug the wing servo wires from the marked fuselage servo extensions.
4. Flip the wing over, and set it on a smooth, soft surface.
5. Remove the servo tape from the wing bottom of the damaged servo.
6. Remove the pushrod clevis from the aileron control horn.
7. Remove the tape strip covering the servo wire.
8. Firmly pull on the servo to remove it from the wing.
9. Remove the servo screw and the servo arm.
Fuselage Servo Replacement
Use the wing servo replacement instructions (1–9) to replace the rudder and/or
elevator servos. Then plug the servo 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.
IMPORTANT: Make sure the glue is dry before proceeding.
9. Connect the aileron servo wires to the proper aileron extension wires in the fuselage.
10. Install the wing.
11. Use clear tape along the length of the servo wire to secure it in place.
Problem Possible Cause Solution
Oscillation
Damaged propeller or spinner Replace propeller or spinner
Imbalanced propeller Balance the propeller
Motor vibration Replace parts or correctly align all parts and tighten fasteners as needed
Loose receiver Align and secure receiver in fuselage
Loose aircraft controls Tighten or otherwise secure parts (servo, arm, linkage, horn and control surface)
Worn parts Replace worn parts (especially propeller, spinner or servo)
Irregular servo movement Replace servo
Inconsistent flight
