13) Mount the control horn to the rudder by in-
serting the two 2mm x 15mm machine screws
through the control horn mounting base, through the
rudder, and into the backplate. Tighten the screws,
but do not overtighten them. You do not want to
crush the wood. See photo # 22 below.

INSTALLING THE ELEVATOR PUSHROD
q
14) Slide one threaded pushrod wire into the
elevator pushrod housing from the fuselage side. Note
that the wire has threads on one end of it. Slide the
plain end of the wire into the pushrod housing.
q
15) Using a modeling knife, cut the clear vinyl
tube into two 1/4” long pieces. Slide one piece of
tubing over one metal clevis. See figure # 10 below.
Figure # 10
This tubing will prevent the clevis from acci-
dentally opening during flight.
q
16) Thread the metal clevis onto the threaded
end of the pushrod wire. For security, thread the cle-
vis on no less than 5/16”.
q
17) Snap the clevis into the third hole out from
the base of the control horn. Move the elevator up
and down with your hand to test for free movement.

18) Install one adjustable servo connector
through the second hole out from the center of one
servo arm. Enlarge the hole in the servo arm using
a 5/64” drill bit to accommodate the servo connec-
tor. Remove the excess material from the servo arm
using a modeling knife. See figure # 11 below.
Figure # 11
After installing the adjustable servo connector
apply a small drop of Kwik Bond Thick C/A to
the nut. This will prevent the connector from loosen-
ing during flight.
q
19) Loosen the set screw in the top of the ad-
justable connector and slide the servo connector/servo
arm assembly over the plain end of the elevator push-
rod wire.
q
20) Use a couple of pieces of masking tape to
hold the elevator in neutral.
q
21) Plug the elevator servo lead into the receiver.
Plug the battery into the motor controller and turn on
the radio system. Center the elevator trim tab on the
transmitter. Place the servo arm onto the servo. The
servo arm should be centered on the servo and point
towards the fuselage side.
q
22) With both the elevator and the servo arm cen-
tered, tighten the set screw in the adjustable servo
connector and remove the excess wire using wire cut-
ters. Remove the masking tape from the elevator and
install the servo arm retaining screw in the servo arm.
