HINGING THE AILERON
Note : e control surfaces, including the ailer-
ons, 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 us-
ing a high-quality thin C/A glue.
Carefully remove the aileron from one of
the wing panels. Note the position of the
hinges.
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. is will help ensure an equal amount
of hinge is on either side of the hinge line
when the aileron is mounted to the aileron.
Slide the wing panel on the aileron until
there is only a slight gap. e 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 should be maintained between the
wing panel and aileron.
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.
Deect the aileron and completely satu-
rate each hinge with thin C/A glue. e
ailerons front surface should lightly con-
tact the wing during this procedure. Ide-
ally, 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.

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.
Using C/A remover/debonder and a paper
towel, remove any excess C/A glue that may
have accumulated on the wing or in the
aileron hinge area.
Repeat this process with the other wing
panel, securely hinging the aileron in
place.
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 applying medium pressure, try-
ing 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.

may need to adjust the size of the precut
opening in the mount. e notch in the
sides of the mount allow the servo lead to
pass through.
Place the servo between the mounting
blocks and space it from the hatch. Use a
pencil to mark the mounting hole loca-
tions on the blocks.

INSTALLING THE STOPPER
ASSEMBLY
Using a modeling knife, carefully cut
o the rear portion of one of the 3 nylon
tubes leaving 1/2” protruding from the
rear of the stopper. is will be the fuel
pick up tube.
Using a modeling knife, cut one length
of silicon fuel line. Connect one end of
the line to the weighted fuel pick up and
the other end to the nylon pick up tube.
1.
Carefully bend the second nylon tube up at
a 45º angle. is tube is the vent tube.
Test t the stopper assembly into the tank.
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.
When satised with the alignment of the
stopper assembly tighten the 3x20mm ma-
chine screw until the rubber stopper ex-
pands and seals the tank opening. Do not
overtighten the assembly as this could cause
the tank to split.
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.

Slide the fuel tank into the fuselage. Guide
the lines from the tank through the hole in
the ewall.
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.

Blow through one of the lines to ensure
the fuel lines have not become kinked inside
