4) Pull the pushrod housings through the servo
compartment until 1/4” of each housing extends be-
yond the outside of the pushrod exit slots.
q
5) Mix a small amount of Kwik Bond 5 Minute
Epoxy. Carefully apply a small amount to the ends
of the pushrod housings where they exit the fuselage.
Use enough epoxy to fill any gaps and remove any
excess using a paper towel and rubbing alcohol. Al-
low the epoxy to fully cure before proceeding. See
photo # 19 below.

6) Slide one pushrod housing through each of
the outer holes in the plywood pushrod support. Slide
the support over the housings until it is flush with the
rear bulkhead.
The pushrod housings should cross inside the
fuselage. Make sure the elevator pushrod hous-
ing exits the right hole in the pushrod support and
that the rudder housing exits the left hole.
q
7) With the pushrod support pushed firmly
against the rear bulkhead, use a modeling knife and
cut off the two housings 1/4” in front of the support.

INSTALLING THE ELEVATOR CONTROL HORN
q
8) The centerline of the elevator control horn is
located on the bottom left side of the elevator (looking
from the rear) 1-1/8” out from the fuselage side. Posi-
tion the control horn so the clevis attachment holes
are directly in-line with the hinge line. The control
horn should also be perpendicular to the hinge line.
See figure # 9 below.

q
9) When satisfied with the alignment, use a
5/64” drill bit, and the control horn as a guide, and
drill the two mounting holes through the elevator.
q
10) Mount the control horn to the elevator by
inserting the two 2mm x 15mm machine screws
through the control horn mounting base, through the
elevator, and into the backplate. Tighten the screws,
but do not overtighten them. You do not want to
crush the wood. See photo # 21 below.

INSTALLING THE RUDDER CONTROL HORN
q
11) The centerline of the rudder control horn
is located on the right side of the rudder (looking
from the rear) 1/2” up from the bottom, at the hinge
line. Position the control horn so the clevis attach-
ment holes are directly in-line with the hinge line.
The control horn should also be parallel with the
top of the fuselage.
Do not install the rudder control horn perpen-
dicular to the hinge line or the pushrod will not
line up when it is installed later. The control horn
should be parallel to the top surface of the fuselage.
q
12) When satisfied with the alignment, use a
5/64” drill bit, and the control horn as a guide, and
drill the two mounting holes through the rudder.
