Instruction Manual.
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.
2)Removeeach hinge fromthewing panel
and aileron and place a T-pin in the center of
each hinge. Slide each hinge into the aileron
untiltheT-pin is snug against the aileron.This
will help ensure an equal amount of hinge is
oneithersideofthehingelinewhentheaileron
is mounted to the wing panel.

3) Slide the aileron on the wing panel until
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
shouldbe maintained betweenthe wingpanel
andaileron.
1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges. 4)Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
aileronsfrontsurfaceshould lightly contactthe
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.
Thehingeisconstructedof 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.

into the aileron servo mount.
2) Secure the servos with the screws pro-
vided with your radio system.
Because the size of servos differ, you
mayneedtoadjustthe size of theprecutopen-
ing in the mount. The notch in the sides of the
mount allow the servo lead to pass through.

8)Afterboth ailerons are securely hinged,
firmly 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 aileron from the wing panel. Use caution
not to crush the wing structure.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
Workthe aileron up and down several
times to “work in” the hinges and
check for proper movement.
Note:
6) Using C/A remover/debonder and a
papertowel, remove anyexcess C/A gluethat
may have accumulated on the wing or in the
aileronhinge area.
5)Turnthe wingpanelover anddeflect the
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge,makingsure that the C/A penetrates into
both the aileron and wing panel.
