6) When you are sure that everything is aligned

correctly, mix up a generous amount of Kwik Bond
5 Minute Epoxy.  Apply a generous layer to the slot
in the horizontal stabilizer and to the entire bottom
surface of the vertical stabilizer.  Set the stabilizer
in place and realign.  Double check all of your mea-
surements once more before the epoxy cures. Hold
the stabilizer in place with masking tape and remove
any excess epoxy using a paper towel and rubbing
alcohol.  Allow the epoxy to fully cure before pro-
ceeding.  See photo # 13 below.

INSTALLING THE TAIL FAIRING

q

7) Using a modeling knife, carefully cut out

the molded plastic tail fairing leaving 1/4” of mate-
rial around the entire perimeter to use as a gluing
surface.  Also remove the material from the top of
the fairing so it can slide around the vertical stabi-
lizer.  See photo # 14 below.

q

8) Using a modeling knife, remove the cover-

ing from over the precut rudder pushrod exit slot in
the top of the fuselage.  The slot is located on the
right top side of the fuselage (looking from the rear),
3-3/4” in front of the rudder hinge line.  The slot is
3/4” long and 1/8” wide.

q

9) Trial fit the tail fairing in place.  It should fit

tightly around the fuselage and the front and sides of
the vertical stabilizer.  Use a modeling knife and 220
grit sandpaper to make any necessary adjustments to
obtain the proper fit.

You may find that the sides of the fairing ex-
tend beyond the trailing edge of the vertical sta-

bilizer.  Use a modeling knife and cut the sides of the
fairing so they are flush with the trailing edge of the
vertical stabilizer before installing the fairing.

q

10) When satisfied with the fit, remove the fair-

ing and lightly sand the inside surfaces that will be
glued to the fuselage, horizontal stabilizer and verti-
cal stabilizer using 220 grit sandpaper.

q

11) Using a ruler and a pen, measure and mark

the location of the rudder pushrod exit slot onto the
plastic fairing.

q

12) Using a modeling knife, cut the slot in the

fairing to match the slot precut in the fuselage.  See
photo # 15 below.

q

13) Slide the fairing back into place.  Double

check the placement of the slot and make any adjust-
ments necessary.  While holding the fairing firmly
in place, carefully trace around it using a pen.

q

14) Using a modeling knife, carefully remove

the covering from inside the outline.

q

15) Mix a small amount of Kwik Bond 5

Minute Epoxy and apply a thin layer to the gluing
surfaces of the fairing.  Slide the fairing into place
and remove any excess epoxy using a paper towel
and rubbing alcohol.  Hold the fairing in place using
pieces of masking tape until the epoxy fully cures.
