The control surfaces, including the
ailerons, elevators, and rudder, are
prehinged with hinges installed, but the
hinges are not glued in place. It is
imperative that you properly adhere the
hinges in place per the steps that follow
using a high-quality thin C/A glue.
1) Carefully remove the aileron from one of
the wing panels. Note the position of the hinges.
2) Remove each hinge from the wing panel
and aileron and place a T-pin in the center of
each hinge. Slide each hinge into the wing
panel until the T-pin is snug against the wing
panel. This will help ensure an equal amount
of hinge is on either side of the hinge line when
the aileron is mounted to the aileron.

3) Slide the wing panel on the aileron until
there is only a slight gap. The hinge is now
centered on the wing panel and aileron.
Remove the T-pins and snug the aileron
against the wing panel. A gap of 1/64” or less
should be maintained between the wing panel
and aileron.

4)Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
ailerons front surface should lightly contact the
wing during this procedure. Ideally, when the

material that allows the C/A to wick or

structure of the wing panel and aileron.
hinges are glued in place, a 1/64” gap or less
will be maintained throughout the lengh of the
aileron to the wing panel hinge line.

5) Turn the wing panel over and deflect the
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge, making sure that the C/A penetrates into
both the aileron and wing panel.
6) Using C/A remover/debonder and a paper
towel, remove any excess C/A glue that may
have accumulated on the wing or in the aileron
hinge area.
To avoid scratching your new aero-
plane we suggest that you cover your work-
bench with an old towel. Keep a couple of jars
or bowls handy to hold the small parts after you
open the bags.
Please trial fit all parts. Make sure you have the
correct parts and that they fit and are aligned
properly before gluing! This will ensure proper
assembly as the
YAK 54
is made from natural
materials and minor adjustments may have to
be made. The paint and plastic parts used
in this kit are fuel proof. However, they are not
tolerant of many harsh chemicals including
the following: paint thinner, cyano-acrylate glue
accelerator, cyanoacrylate glue de-bonder and
acetone. Do not let these chemicals come in
contact with the colours on the covering and
the plastic parts.
