HINGING THE FLAP
Note :
he control surfaces, including the ailerons,
elevators, and rudder, are prehinged with hinges in-
stalled, 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.
- Carefully remove the lap from one of the wing
panels. Note the position of the hinges.
- Remove each hinge from the wing panel and lap
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 when the lap is mounted to the aileron.
- Slide the wing panel on the lap until there is only
a slight gap. he hinge is now centered on the wing
panel and lap. 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 lap.
NOTE : he hinge is constructed of a special
material that allows the C/A to wick or penetrate
and distribute throughout the hinge, secure-
ly bonding it to the wood structure of the wing
panel and lap.
- Delect the lap and completely saturate each
hinge with thin C/A glue. he ailerons front surface
should lightly contact the wing during this proce-
dure. Ideally, when the hinges are glued in place,
a 1/64” gap or less will be maintained throughout
the lengh of the lap to the wing panel hinge line.
- Turn the wing panel over and delect the lap in
the opposite direction from the opposite side. Ap-
ply thin C/A glue to each hinge, making sure that
the C/A penetrates into both the aileron and wing
panel.
- Using C/A remover/debonder and a paper towel,
remove any excess C/A glue that may have accu-
mulated on the wing or in the lap hinge area.
- Repeat this process with the other wing panel, se-
curely hinging the aileron in place.
- Ater both lap are securely hinged, irmly grasp
the wing panel and aileron to make sure the hinges
are securely glued and cannot be pulled out. Do
this by carefully applying medium pressure, trying
to separate the lap from the wing panel. Use cau-
tion not to crush the wing structure.
