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.
1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
2)Removeeach hinge fromthewingpanel
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.

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.
4)Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
aileronsfrontsurfaceshould lightly contactthe

hinges are glued in place, a 1/64” gap or less
will be maintained throughout the lengh of the

HINGING THE RUDDER.
Glue the rudder hinges in place using the
same techniques used to hinge the ailerons.
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.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
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.

opposite side. Apply thin C/A glue to each
hinge,makingsurethat the C/A penetrates into

Workthe aileron up and down several
times to “work in” the hinges and

5) With the stopper assembly in place,
the weighted pick-up should rest away from
therear of the tank and move freely insidethe
tank. The 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 satisfied with the alignment of
the stopper assembly tighten the 3 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.
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.
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.

MOUNTING THE ENGINE.
1) Install the pushrod housing through the
predrilledholein the firewallandinto the servo
compartment. The pushrod housing should
protrude 1/4" out past the front of the firewall.
Make a Z-Bend 1/4" from one end of the plain
wire pushrod.
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
thetank isinstalled inside the fuselage, itmay
be difficult to determine which is which.

4) Remove the engine. Using an drill bit,
drill the mounting holes through the engine
mount at the four locations marked.
6) Attach the Z-Bend in the pushrod wire
to the throttle arm on the carburetor.
5) Bolt the engine to the engine mount
using the four machine screws. Double
cheek that all the screws are tight before
proceeding.
Blow through one of the lines to en-
sure the fuel lines have not become kinked
inside the fuel tank compartment. Air
