HINGING THE AILERONS.
Note : e 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 aileron
until the T-pin is snug against the aileron.
is will help ensure an equal amount of
hinge is on either side of the hinge line when
the aileron is mounted to the wing panel.
3) Slide the aileron on the wing panel until
there is only a slight gap. e 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) Deect the aileron and completely satu-
rate each hinge with thin C/A glue. e 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 : e 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.
5) Turn the wing panel over and deect the
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge, making sure that the C/A penetrates
into both the aileron 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
aileron hinge area.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
8) Aer both ailerons are securely hinged,
rmly grasp the wing panel and aileron to
make sure the hinges are securely glued and
cannot be pulled out. Do this by carefully ap-
plying medium pressure, trying to separate
the aileron from the wing panel. Use caution
not to crush the wing structure.
Work the aileron up and down sev-
eral times to “work in” the hinges
and check for proper movement.

It may be necessary to remove some of the
ashing around the tank opening using a
modeling knife. If ashing is present, make
sure none falls into the tank.
5) With the stopper assembly in place, the
weighted pick-up should rest away from the
rear of the tank and move freely inside the
tank. e top of the vent tube should rest just
below the top of the tank. It should not touch
the top of the tank.
6) When satised with the alignment of the
stopper assembly tighten the 3 x 20mm ma-
chine screw until the rubber stopper expands
and seals the tank opening. Do not over-
tighten the assembly as this could cause the
tank to split.
FUEL TANK INSTALLATION.
You should mark which tube is the vent
and which is the fuel pickup when you attach
fuel tubing to the tubes in the stopper. Once the
tank is installed inside the fuselage, it may be
dicult to determine which is which.
7) Slide the fuel tank into the fuselage. Guide
the lines from the tank through the hole in
the rewall.
