8. Use a pin vise and 5/64-inch (2mm) drill bit to
enlarge the hole in the servo horn. Enlarge the hole
that is 1/2-inch (13mm) from the center of the horn
as shown. Use side cutters to remove any unused
arms so they don’t interfere with the operation of
the servo.
9. Pass the Z-bend in the pushrod through the
hole enlarged in the previous step. With the
servo centered, attach the servo horn to the servo
using the screw provided with the servo and a #1
Phillips screwdriver.
10. Repeat steps 6 through 9 to install the elevator
pushrod. Make sure to install a clevis for both
elevator control horns

11. With the radio system on and the rudder and
elevator servos centered, check that the control
surfaces are aligned with the fixed surfaces. Use a
ruler between the two surfaces. Adjust the clevis as
necessary to align the surfaces. Once aligned, slide
the silicone tubing over the forks of the clevis to
prevent them from opening accidentally. Check both
elevator and the rudder at this time.
