Hinging The Ailerons - Seagull Models Extra 260 Assembly Manual

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 before
gluing! This will ensure proper as-
sembly as the EXTRA 260 is made
from natural materials and minor ad-
justments 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.

HINGING THE AILERONS.

Note:
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.

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.
saturate each hinge with thin C/A glue. The
ailerons front surface should lightly contact the
wing during this procedure. Ideally, when the
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.
Note: The hinge is constructed of a special
material that allows the C/A to wick or penetrate
and distribute throughout the hinge, securely
bonding it to the wood structure of the wing
panel and aileron.
