tube for the rudder. It is easiest to start by inserting the
pushrod in the opening in the firewall to prevent bending
it around the fuselage structure.
o Step 9
Replace the standard servo arm on the elevator servo
with a standard double arm. Use a 5/64-inch (2mm)
drill bit and pin drill to enlarge the outer hole in the
rudder servo arm.
o Step 10
Secure the pushrod wire using one of the snap links
provided with your Piper Pawnee 40.
Note: The elevator and rudder pushrods are
connected to the outer hole on the standard
double arm that comes with the servo and
they are connected to the middle hole on the
control horns for both rudder and elevator.
o Step 11
Turn on the radio system and plug the servo into the
receiver. Attach the clevis to the middle hole of the control
horn as shown. It will be necessary to thread the clevis in
or out on the pushrod wire to center the control surface
while the radio is on and the servo centered.
