
Step 1
Locate the items necessary to install the rudder linkage and to
connect the steering pushrod wire to the rudder servo horn.
 Step 2
With the radio system on, center the rudder stick and trim.
Remove the standard servo horn from the rudder servo and
place a 180-degree horn on the rudder servo. The horn will
align perpendicular to the servo centerline as shown. If not,
rotate the arm 180-degrees as there are an odd number of
splines on the servo output and this usually corrects the
alignment issue.
 Step 3
Use a pin vise and 5/64-inch (2mm) drill bit to enlarge a hole on
the servo horn that is 9/16-inch (14mm) from the center of the
servo horn on the side closest to the steering pushrod wire.
 Step 4
Use a pin vise and 5/64-inch (2mm) drill bit to enlarge a hole
on the servo horn that is 1/2-inch (12mm) from the center of
the servo horn on the side closest to the rudder pushrod tube.
 Step 5
Remove the horn from the servo. Insert the pushrod
connector in the outer hole of the servo horn.
