2. Once you are satisfi ed with the fi t of the stabilizer
halves, remove the stabilizer halves and the joiner tubes.
Use medium grit sandpaper to roughen up the aluminum
tubes. Clean the tubes with denatured alcohol and insert
both tubes back into the fuselage until the end exits on
the opposite side by approximately 1" [25mm].
❏
3. Gather everything required for gluing the stabilizer
halves to the fuselage including 30-minute epoxy, mixing
sticks, epoxy brush, 12" [304mm] 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.
Fw 190 FACT
The Focke-Wulf Fw 190 was designed so that
minimal trim changes were required at various
speeds. The ailerons and rudder did not require
adjustable in-fl ight trim tabs. Small, fi xed trim
tabs were attached to the trailing edge and were
adjusted during the initial fl ight. However, the
horizontal stabilizer was adjustable using an
electric motor. It could be adjusted from -3 to +5
degrees of incidence.

4. Without using any glue, install four 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 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
dampened with denatured alcohol.
❏
7. Please read the complete instructions in this step
before mixing up the epoxy. Mix up approximately ¼ 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 pivot pin. Wipe away any excess epoxy around the
outside of the holes with a paper towel dampened with
denatured alcohol.
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.
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 on.
Move the rudder left and right a few times to align the
hinges and make certain that the rudder defl ects left
and right enough. Alloy the epoxy to cure, checking it
a couple of times while it cures.
