4) Deflect the flap and completely saturate
each hinge with thin C/A glue. The flap front
surface should lightly contact the wing dur-
ing this procedure. Ideally, when the hinges
are glued in place, a 1/64” gap or less will be
maintained throughout the lengh of the flap
to the wing panel hinge line.
NOTE : The 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 flap.
5) Turn the wing panel over and deflect the
flap in the opposite direction from the oppo-
site side. Apply thin C/A glue to each hinge,
making sure that the C/A penetrates into
both the flap and wing panel.
6) Using C/A remover/debonder and a pa-
per towel, remove any excess C/A glue that
may have accumulated on the wing or in the
flap hinge area.
7) Repeat this process with the other wing
panel, securely hinging the flap in place.
8) After both flap are securely hinged, firmly
grasp the wing panel and flap to make sure
the hinges are securely glued and cannot
be pulled out. Do this by carefully apply-
ing medium pressure, trying to separate the
flap from the wing panel. Use caution not to
crush the wing structure.
Work the flap up and down several
times to “work in” the hinges and
check for proper movement.
Note :
Note : The control surfaces, including the ai-
lerons, elevators, and rudder, are prehinged
with hinges installed, but the hinges are not
glued in place. It is imperative that you prop-
erly 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.
