4)Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
aileronsfrontsurfaceshould 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:
The control surfaces, including the
ailerons, elevators, and rudder, are
prehinged with hinges installed, but the
hinges are not glued in place. It is
imperativethat you properly adhere the
hingesin place per the steps that follow
usinga high-qualitythin C/A glue.
1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
2)Removeeach hinge from thewingpanel
and aileron and place a T-pin in the center of
each hinge. Slide each hinge into the aileron
untiltheT-pinis snugagainst the aileron.This
will help ensure an equal amount of hinge is
oneithersideofthehingelinewhentheaileron
is mounted to the wing panel.
HINGINGTHE AILERONS
Note:
The hinge is constructed of a special
material that allows the C/A to wick or
penetrateanddistributethroughout the
hinge, securely bonding it to the wood
structureof the wingpanel and aileron.
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 wing panel
andaileron.
5)Turn the wingpanel over anddeflect the
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge,makingsure that the C/Apenetratesinto
both the aileron and wing panel.
6) Using C/A remover/debonder and a
papertowel, remove anyexcessC/A glue that
may have accumulated on the wing or in the
aileronhinge area.

8)Afterbothailerons are securelyhinged,
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.
Note:Work the aileron up and down several
times to “work in” the hinges and check
for proper movement.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
1) Carefully remove the elevator from one
of the horizontal stabilizer panels. Note the
position of the hinges.
2) Remove each hinge from the horizontal
stabilizerpaneland elevator andplace a T-pin
in the center of each hinge. Slide each hinge
intothe elevatoruntil theT-pinis snug against
the elevator. This will help ensure an equal
amount of hinge is on either side of the hinge
line when the elevator is mounted to the
horizontal stabilizer panel.
HINGINGTHE ELEVATORS
3) Slide the elevator on the horizontal
stabilizer panel until there is only a slight gap.
The hinge is now centered on the horizontal
stabilizer panel and elevator. Remove the T-
pins and snug the elevator against the
horizontal stabilizer panel. A gap of 1/64” or
less should be maintained between the
horizontal stabilizer panel and elevator.
4)Deflect the elevator and completely
saturate each hinge with thin C/A glue. The
elevators front surface should lightly contact
thehorizontal stabilizer during this procedure.
Ideally, when the hinges are glued in place, a
1/64”gaporlesswillbemaintainedthroughout
the lengh of the elevator to the horizontal
stabilizer panel hinge line.
Note: The hinge is constructed of a special
material that allows the C/A to wick or
penetrateanddistributethroughout the
hinge, securely bonding it to the wood
structure of the horizontal stabilizer
paneland elevator.
5) Turn the horizontal stabilizer panel over
and deflect the elevator in the opposite
directionfromthe opposite side.ApplythinCA
glue to each hinge, making sure that the C/A
penetratesintoboth the elevatorandhorizontal
stabilizer panel.

INSTALLING THE STOPPERASSEMBLY
 1) Using a modeling knife, carefully cut off
the rear portion of one of the 3 nylon tubes
leaving 1/2” protruding from the rear of the
stopper. This will be the fuel pick up tube.
2) Usinga modeling knife,cut onelength
of silicon fuel line. Connect one end of the
line to the weighted fuel pickup and the other
end to the nylon pickup tube.
3) Carefully bend the second nylon tube
up at a 45º angle. This tube is the vent tube.

5) With the stopper assembly in place, the
weighted pickup should rest away from the
rearofthe tankandmovefreelyinsidethetank.
Thetop of thevent tubeshould rest justbelow
the top of the tank. It should not touch the top
of the tank.
6) When satisfied with the alignment of the
stopper assembly tighten the 3mm x 20mm
machine 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.
Carefully use a lighter or heat gun to
permenently set the angle of the vent tube.
Important: When the stopper assembly is in-
stalled in the tank, the top of the vent tube
should rest just below the top surface of the
tank. It should not touch the top of the tank.
4) Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using a
modeling knife. If flashing is present, make
sure none falls into the tank.
Slide the tank into the fuselage from inside so
that the neck is at the top of the fuselage and
itlocates through theengine bulkhead. Gently
secure it to the top horizontal former with a
cable tie.
Blow through one of the lines to ensure
thefuel lines have not becomekinked in-
sidethefueltankcompartment. Airshouldflow
througheasily.
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
difficult to determine which is which.
Attach the silicone fuel and pressure pipes to
the tank. The lower pipe is the ‘feed’ and the
upper two the ‘pressure and fill’. The fill pipe
is the next pipe.
