Section 8-Rudder Servo and Pull/Pull Installation

Required Tools and Adhesive
• Z-42 thread locker (Pacer)
• Thin C/A
• 0.05 Allen wrench
• (4) full-threaded servo screws
• Wire Cutter
Step 1
Install rudder servo the way that
output shaft is towards the rear of
the fuselage.
Step 2
Check provided pull/pull cable to
make sure its covered with plastic, if
not take a piece of inner Ny-Rod and
slip a long piece over one of the
cables. This will prevent radio
interference.
Step 3
Insert the cable connector sleeve
over the cable through the small end
of the connector. Bend a ¼ inch
length of cable back 180 degrees.
Pull the cable back thru the threaded
end of the connector and insert the
4-40 threaded rod and tighten with a
0.050 Allen wrench. Important: Be
sure to use Pacer Z-42 Thread
Locker or similar on the 4-40
threaded rod that goes into the cable
connector sleeve.
Make careful measurements on the
final length needed before you attach
the cable connectors on the final end
of the cable. You do have some
length adjustment available but most
of that adjustment should be for the
final cable tightening process.

Step 4
To attach the round plastic servo
arm to the CF arm you need to open
up the CF arm hole enough to fit the
round servo arm in it.
Step 5
Attach the black double CF rudder
servo arm as shown in Figure 30
with four small screws (servo
mounting type), not provided and run
thin C/A for extra safety.
Step 6
Cut the bottom of screws with your
cutter to avoid any contact with the
servo case.
Step 7
Quickly connect your servo to your
receiver and make sure all the trims
and sub trims are set to zero and
servo is centered. Then insert the CF
arm to servo output shaft.
