Section 7-Elevator Servo Installation

Required Tools and Adhesive
• (2) 24" servo extension
• Sullivan inner nyrod
• Pin vise
• 1/16"drill bit
• 1 ½" Airwild aluminum servo
arms
Step 1
Attach 24-inch servo extension wires
to the elevator servos. You may want
to wrap the servo plug connections
with a small piece of tape.
Step 2
To run the servo extension wires
forward, use a piece of Sullivan inner
Nyrod and place it through the oval
holes in the bottom of the fuse
formers starting from the canopy
hatch area and exiting through the
elevator servo mounting opening.
Step 3
Use a piece of tape and attach the
Nyrod to the end of the elevator
extension servo wire and gently pull
the extension through the oval holes
exiting into the canopy hatch area.
See Figure 26.

Step 4
Mount both elevator servos. Drill
1/16" pilot holes with a pin vise into
the hardwood servo mounting rails
for the servo mounting screws.
Mount the servos so the output shaft
end of the servo is toward the rear of
the fuselage.

Step 5
Set the sub trims and trim at zero
and install a good quality aluminum
servo arm such as Airwild aluminum
arm perpendicular to the main servo
axis with a length of 1 1/2".
