HINGING THE AILERON.

Note : he control surfaces, including the ailer-
ons, 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 us-
ing 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. his will help ensure an equal amount
of hinge is on either side of the hinge line

3) Slide the wing panel on the aileron until
there is only a slight gap. he hinge is now
centered on the wing panel and aileron. Re-
move 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) Delect the aileron and completely satu-
rate each hinge with thin C/A glue. he ailer-
ons 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 : he hinge is constructed of a spe-
cial 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.
