NOTE:

To avoid scratching your new aero-
plane we suggest that you cover
your workbench 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 be-
fore gluing! This will ensure proper
assembly as the 

PC-9

  is made from

natural materials and minor adjust-
ments 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 chemi-
cals including the following: paint
thinner, cyano-acrylate glue accel-
erator, cyanoacrylate glue de-bonder
and acetone. Do not let these chemi-
cals come in contact with the colours
on the covering and the plastic parts.

 

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

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 aileron
until the T-pin is snug against the aileron. This
will help ensure an equal amount of hinge is
on either side of the hinge line when the aileron
is mounted to the wing panel.

HINGING THE AILERONS.

Note:

 

3) Slide the aileron on the wing panel 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.
