epoxy, mixing sticks, epoxy brush, 12" [305mm] long
dowel or wire, masking tape, denatured alcohol and
small paper towel squares. Mix up 3/4 oz. [22.1cc] of
30-minute epoxy. Apply a generous amount of epoxy
to the long side of the aluminum joiner tubes. Pull
the tubes through the fuselage so that they are close
to centered. Pour a small amount of epoxy into both
holes of one of the stabilizer halves and using a dowel
or wire, coat the inside of the holes. Apply epoxy to
the root rib of the stabilizer and the fuselage. Insert
the end of the aluminum tubes with epoxy on them
into the stabilizer and press the stabilizer against
the fuselage. Wipe off any excess epoxy that may
have squeezed out before it runs down the fuselage.
Quickly repeat the process on the other side. Wipe
off any excess epoxy with a dampened paper towel
and denatured alcohol. Use pieces of masking tape
to hold the stabilizer tight against the fuselage until
the epoxy cures.

4. Without using any glue, install fi ve hinges
into the rudder. Note that the pivot point of each
hinge must align with the center of the leading edge.
To achieve this alignment, the hinges will be fairly
deep in the rudder. Also note that the hinges must be
perpendicular to the leading edge.

5. Again without glue, test fi t the rudder to
the fi n. Move it left and right a few times to align the
hinges. The rudder doesn’t have to move very far,
only 2" [50.8mm] left and 2" [50.8mm] right measured
at the widest part of the rudder at the trailing edge. If
there is too much resistance, or if you are not able to
move the rudder left and right 2" [50.8mm], widen the
gap slightly between the rudder and the fi n.

6. Remove the rudder and all the hinges. Add
a small drop of oil to the pivot point on the hinges.
This will prevent the epoxy from adhering to the pivot
point. Make sure oil does not get on the gluing surface
of the hinge. If it does, clean the oil off with a paper
towel square dampened with denatured alcohol.

7. Mix up approximately 1/4 oz. [7.4cc] of
30-minute epoxy. Use a toothpick to thoroughly apply
the epoxy in the holes in the fi n and rudder. Use the
toothpick to get the epoxy out of the opening of the
holes in the rudder and fi n so it doesn’t get into the
hinge pin. Wipe away any excess epoxy around the
outside of the holes with a couple of the small paper
towel squares dampened with denatured alcohol.

8. Use the toothpick to apply epoxy to the ends
of the rudder hinges that go into the fi n. Insert each
hinge into the fi n and wipe away any excess epoxy
that squeezes out of the hole.
❏
❏
9. Apply epoxy to the other end of the hinges.
Join the rudder to the fi n, pushing the hinges only
about 3/4 of the way into the rudder. Use a toothpick
to wipe away any epoxy that squeezes out. Then, fi t
the rudder the rest of the way in.
