Rudder And Elevator Servo Installation - Horizon Fitness Hangar9 Carbon Cub 15cc Manuel D'utilisation

8. Repeat steps 5 and 6, only passing the cable through the
fi ttings instead of the cable ends. The cables should have
very light tension. Make sure the rudder and stabilizer are
square as illustrated in the stabilizer installation section
of this manual.

RUDDER AND ELEVATOR SERVO INSTALLATION

1. Locate the rudder and elevator control horns. The taller
control horn is used for the elevator, and the shorter horn
for the rudder. Use sandpaper to scuff the bottom of the
control horns. Use a paper towel and isopropyl alcohol to
remove any oils or debris from the control horns.
2. Check the fi t of the elevator control horn. Make sure
the horn does not protrude through the top, deforming
the covering. If so, lightly sand the horn so it is fl ush on
the top when installed. Use 5-minute epoxy to glue the
elevator horn in position. Use the technique outlined
earlier when installing the horns.
3. Check the fi t of the rudder control horn. Make sure
the horn does not protrude through the opposite side,
deforming the covering. If so, lightly sand the horn so it is
fl ush on the opposite side when installed. Use 5-minute
epoxy to glue the rudder horn in position. Use the
technique outlined earlier when installing the horns.
4. Use a 2.5mm hex wrench to remove the screw from the
servo hatch. Lift the hatch and set it aside.

5. Install the rudder and elevator servos in the fuselage with
the servo outputs facing toward the front of the fuselage.
Mark, drill and prepare the servo mounting holes as
outlined earlier in this manual.
6. Locate the 28-inch (711mm) elevator pushrod. Insert the
pushrod through the front of the fuselage.
7. Direct the pushrod through the fuselage toward the rear
where the pushrod tubes are located.
8. Guide the pushrod it into the elevator pushrod tube
located slightly behind the servo compartment.
9. Use the radio system to center the elevator servo. Prepare
the servo arm by removing any arms that may interfere
with the operation of the servo. Use a pin vise and 5/64-
inch (2mm) drill bit to enlarge the hole in the arm that is
5/8-inch (16mm) from the center of the arm. Attach the
z-bend of the pushrod to the servo arm, then attach the
arm to the servo using the hardware provided with the
servo.
