Note : e 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 ap from one of the
wing panels. Note the position of the hinges.
2) Remove each hinge from the wing panel
and ap 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. is will help ensure an equal amount
of hinge is on either side of the hinge line
when the ap is mounted to the wing.

each hinge with thin C/A glue. e ap’s
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 ap to the wing panel hinge line.
NOTE : e 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 ap.

8) Aer both ap are securely hinged, rmly
grasp the wing panel and ap to make sure
the hinges are securely glued and cannot
be pulled out. Do this by carefully applying medium pressure, trying to separate the
ap from the wing panel. Use caution not to
