servo. Use a pin vise and 5/64-inch (2mm) drill bit
to enlarge the hole in the servo arm that is 3/8-inch
(9.5mm) from the center of the horn. Use side cutters
to remove any unused arm from the horn so they
don’t interfere with the operation of the servo.

stock servo horn from the servo. Install the servo
horn prepared in Step 6 on the servo. Note the
position of the servo horn for the rudder and
elevator servos.

the servo in the servo tray at an angle, then rotating
it into position. Note that the output shaft on the
servo faces to the front of the fuselage.
 10. Slide the rudder servo into position. The
rudder pushrod will align with the hole in the
servo horn enlarged in Step 6. Use a pencil to
mark the location for the servo mounting screws
on the servo tray.
 11. Remove the servo from the servo tray. Use a pin
vise and 1/16-inch (1.5mm) drill bit to drill the four
holes for the servo mounting screws.
