STEP 1: INSTALLING THE RUDDER SERVO
Install the rubber grommets and brass collets onto your rudder servo,
making sure to install the collets with the flanges toward the bottom of
the servo.
Install the rudder servo into the plywood servo tray, making sure to
drill 1/16" diameter pilot holes for the mounting screws.
IMPORTANT
The servo output shaft should be toward the back
of the fuselage, as shown.
STEP 2: INSTALLING THE RUDDER PUSHROD ASSEMBLY
Using a modeling knife, cut away and remove the covering material
from over the rudder pushrod exit hole in each side of the fuselage. The
holes are located 5-1/4" in front of the rudder hinge line and 5/8" above
the top of the horizontal stabilizer.
Using a modeling knife, cut away two arms from a "4-point" servo horn.
Enlarge the hole in each arm that is 9/16" out from the center of the
servo arm, using a 5/64" diameter drill bit.
