Cowling Installation - Horizon Hobby ARF Hangar 9 Manuel D'utilisation

21. Install the throttle servo in the servo tray following the procedure
outlined for the aileron servo. Center the servo using the radio
system and install the servo arm on the servo perpendicular to the
servo centerline. Use side cutters to remove any arms that may
interfere with the operation of the servo.
22. Mount the throttle servo connector in the throttle servo arm so it is
7/16-inch (11mm) from the center of the servo arm. Place a drop
of canopy glue on the M2 nut, then install it on the underside of the
arm to secure the connector.
23. Slide the servo into position by guiding the pushrod wire through the
fi tting. The servo will fall naturally against the inside of the fuselage.
Use 15-minute epoxy to glue the servo tray to the inside of the
fuselage.
24. Move the carburetor and servo to the low-throttle position and
tighten the setscrew securing the pushrod to the connector at the
servo.
25. Use side cutters to trim the excess wire. Check the operation of the
carburetor using the radio system. Make any adjustments necessary
to fully open and close the carburetor using the radio system.
