3)
Remove the stabilator from the fuselage. Using
220 grit sandpaper, lightly sand only the portion of the
aluminum tube beyond the mark you drew.
☛
Sanding the tube will roughen the surface. This will
make the epoxy adhere to the aluminum much better. Do
not omit this step.
❑
4)
Slide the stabilator back into place and realign
it. While holding the stabilator in place, slide one nylon
retainer over the end of the aluminum tube and push it up
against the nylon sleeve.
❑
5)
Mix a small quantity of Kwik Bond 5 Minute
Epoxy and apply a couple of drops of epoxy to the joint
between the nylon retainer and the aluminum tube. Re-
move any excess epoxy using a paper towel and rubbing
alcohol, and allow the epoxy to set up before proceeding.
See photo # 28 below.

☛
The nylon retainer will prevent the stabilator from
sliding out during flight.

6)
Repeat steps # 1 through # 5 to install the second
stabilator on the other side of the fuselage.
INSTALLING THE PUSHRODS
❑
7)
Locate one "dual arm" servo horn for your servo.
Using a drill with a 1/16" drill bit, enlarge the two holes
that are 5/16" out from the center of the horn.

9)
Plug both servos and the ESC into their proper
slots in the receiver. Plug the flight battery into the ESC
and turn on the radio system. Center the servos using the
trim levers on the transmitter.
❑
10)
Attach the servo horn to one servo, making sure
that the servo horn is centered. Install and tighten the
servo horn retaining screw, provided with your servo, to
secure the servo horn into place.
❑
11)
Carefully slide the nylon actuator arm over the
end of the aluminum tube and align it. The side of the
nylon arm should be even with the end of the aluminum
tube. See photo # 30 below.
❑
2)
While holding the stabilator in place, use a pen-
cil to draw a mark on the aluminum tube where it and the
nylon insert meet. See photo # 27 below.
❑
8)
Install the two prebent pull-pull rods into the
holes that you enlarged in the servo horn and into the holes
in the nylon actuator arm. Orientate the parts as shown.
See photo # 29 below.

12)
When satisfied with the alignment, remove the
actuator arm and mix a small quantity of Kwik Bond 5
Minute Epoxy. Apply a thin layer of epoxy to the end of
the aluminum tube, only where the actuator arm will be
glued into place.
❑
13)
Slide the actuator arm back into place and re-
align it. Before the epoxy sets up, carefully center the
stabilator. The leading edge of the stabilator should be
lined up with the mold line on the side of the fuselage.
When satisfied with the alignment, hold the stabilator
aligned until the epoxy sets up.
❑
14) Repeat steps # 7 through # 13 to install the
second stabilator pushrod assembly.
