2)
Using a modeling knife, remove the covering
from over the elevator pushrod exit hole in the back of
the fuselage. The hole is located on the right side of the
fuselage, 1-3/4" in front of the rudder hinge line and 5/8"
down from the bottom of the horizontal stabilizer.
❑
3)
Carefully insert the plain end of the elevator push-
rod wire (with the control horn still attached) into the hole
in the right side of the fuselage. Slide the wire in until the
control horn lines up with the elevator hinge line.
❑
4)
To properly align the control horn, it should be
perpendicular to the elevator hinge line and its centerline
should be 3/4" out from the side of the fuselage, at the
hinge line. The clevis attachment holes should be located
directly over the hinge line. See figure # 10 below.

☛
You may need to bend the elevator pushrod wire out
slightly (where it exits the fuselage side). This will make
it easier to line up the control horn and will prevent the
pushrod from binding.
❑
5)
When satisfied with the alignment, use a drill with
a 5/64" drill bit and the control horn as a guide, and drill the
two mounting holes through the elevator.
❑
6)
Slide the control horn back into place and re-
align it. Push two 2mm x 12mm machine screws into
the base of the control horn and through the elevator.

7)
Place the nylon backplate onto the machine
screws, aligning the two holes in the backplate with the

INSTALLING THE SERVO CONNECTOR
❑
8)
Locate one plastic "4-point" servo horn that came
with your servo. One of the arms should have at least
four holes in it.
❑
9)
Using a pair of wire cutters, carefully remove all
of the arms except the one with four holes in it.
❑
10) Using a drill with a 5/64" drill bit, enlarge the
third hole out from the center of the arm.
❑
11)
Install one adjustable servo connector through
the hole that you enlarged. When you thread on the nut,
don't tighten it completely. You don't want the connector
loose, but you do want it to be able to rotate without bind-
ing too much. See photo # 30 below.

☛
If your servo arm is thinner than the standard sized
arms, we recommend that you install a thin washer be-
tween the servo arm and the servo connector nut. This
will prevent slop between the arm and the connector.
❑
12) Apply a couple of drops of Kwik Bond Thin
C/A to the connector nut and allow the C/A to fully dry.
The C/A will lock the nut in place and will prevent the
connector from loosening during flight.
control horn. Orientate the pushrod wire so that the longer
portion of the wire is on the right side of the control horn.

two screws. Using a # 1 phillips screwdriver, evenly
tighten both machine screws to draw the backplate into
place. Be careful not to overtighten the screws. You
don't want to crush the wood. See photo # 29 below.
