When the stopper assembly is installed 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.
5. 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 of it falls into the tank.
6. When satisfied with the alignment of the
stopper assembly tighten the 3mm x 20mm
machine 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.
7. Using a modeling knife, cut 3 lengths of
fuel line 150mm long. Connect 2 lines to the 2
vent tubes and 1 line to the fuel pickup tube in
the stopper.
Blow through one of the lines to ensure
the fuel lines have not become kinked inside
the fuel tank compartment. Air should flow
through easily.
9. To secure the fuel tank in place, apply a
bead of silicon sealer to the forward area of
the tank, where it exits the fuselage behind the
engine mounting box and to the rear of the tank
at the forward bulkhead.
Do not secure the tank into place
permanently until after balancing the airplane.
You may need to remove the tank to mount
the battery in the fuel tank compartment
8. Feed three lines through the fuel tank
compartment and through the pre-drilled hole
in the firewall. Pull the lines out from behind
the engine, while guiding the fuel tank into
place. Push the fuel tank as far forward as
possible, the front of the tank should just about
touch the back of the firewall.

Locate the long piece of wire used for the
throttle pushrod. One end of the wire has
been pre-bend in to a “Z” bend at the factory .
This “Z” bend should be inserted into the
throttle arm of the engine when the engine is
fitted onto the engine mount. Fit the engine
to the engine mount using the screws
provided.
COWLING
1) Slide the fiberglass cowl over the en-
gine and line up the back edge of the cowl
with the marks you made on the fuselage.
2) While keeping the back edge of the
cowl flush with the marks, align the front of
the cowl with the crankshaft of the engine. The
front of the cowl should be positioned so the
crankshaft is in nearly the middle of the cowl
opening. Hold the cowl firmly in place using
pieces of masking tape.
3) Slide the cowl back over the engine
and secure it in place using four wood
screws.See picture below.

5) When you are sure that everything is
aligned correctly, mix up a generous amount
of 30 minute epoxy. Apply a thin layer to the
top and bottom of the stabilizer mounting area
and to the stabilizer mounting platform sides
in the fuselage. Slide the stabilizer in place and
re-align. Double check all of your
measurements one more time before the
epoxy cures. Remove any excess epoxy using
a paper towel and rubbing alcohol and hold
the stabilizer in place with T-pins or masking
tape.
6) Af ter the epoxy has fully cured, remove
the masking tape or T -pins used to hold the
stabilizer in place and carefully inspect the
glue joints. Use more epoxy to fill in any
gaps that were not filled previously and
clean up the excess using a paper towel and
rubbing alcohol.
1) Using a modeling knife cut away the
covering from the horizontal fin for the rudder
and remove it.
VERTICAL INSTALLATION
2) Put the rudder into the fuselage as same
as picture below.
1) Using a modeling knife, cut away the
covering from the fuselage for the stabilizer
and remove it.
2) Draw a center line onto the horizontal
stabilizer. Then slide the horizontal into the
fuselage.
HORIZONT AL ST ABILIZER INST ALLA TION
3) Mark the shape of the vertical on the
left and right sides onto the horizontal
stabilizer using a felt-tip pen
4) Remove the stabilizer. Using the lines
you just drew as a guide, carefully remove the
covering from between them using a modeling
knife.
When cutting through the covering to remove
it, cut with only enough pressure to only cut
through the covering it’s self. Cutting into the
balsa structure may weaken it. This could lead
to possible failure during flight
Center line.
Remove covering.
MATRIX. INSTRUCTION MANUAL

4) Now, remove the rudder and using a
modeling knife, carefully cut just inside the
marked lines and remove the film of the rudder.
Just as you did with the horizontal stabilizer,
make sure you only press hard enough to cut
the film, not the balsa rudder.
3) Mark the shape of the vertical on the left
and right side on the rudder using a felt-tip
pen.
5) Put the vertical stabilizer back in place.
Using a triangle, check to ensure that the
vertical stabilizer is aligned 90 degree to the
horizontal stabilizer .
Remove covering.
6) When you are sure that everything is a
aligned correctly, mix up a generous amount
of 30 minute epoxy. Apply a thin layer to the
slot in the mounting platform and to the vertical
stabilizer mounting area. Apply epoxy to the
lower rudder hinge. Set the stabilizer in place
and re-align. Double check all of your
measurements once more before the epoxy
cures. Remove any excess epoxy using a
paper towel and rubbing alcohol and hold the
stabilizer in place with T -pins or masking tape.
Allow the epoxy to fully cure before proceeding.

lead into the receiver. Y ou may want to plug
an aileron extension into the receiver to make
plugging in the aileron servo lead easier
when you are installing the wing . Plug the
battery pack lead into the switch.
2) Wrap the receiver and battery pack in
the protective foam to protect them from
vibration. Use a rubber band or masking tape
to hold the foam in place.
3) Position the battery pack and receiver
behind the fuel tank. Use the two light plywood
pieces, placed over the battery and receiver
and glue to the fuselage sides to hold the
battery and receiver securely in place. Use
15mm triangle pieces glued between the
fuselage sides and the plywood pieces to
reinforce the joints.
Do not permanently secure the receiver and
battery until after balancing the model.
4) Using a 2mm drill bit, drill a hole through
the side of the fuselage, near the receiver , for
the antenna to exit.
