2. Draw a center line onto the horizontal stabilizer.
3. Check the fit of the horizontal stabilizer in its slot.
Make sure the horizontal stabilizer is square and
centered to the fuselage by taking measurements,
but don't glue anything yet.
4. With the horizontal stabilizer correctly aligned, mark
the shape of the fuselage on the top and bottom of
the tail plane using a water soluble /
non-permanent felt-tip pen.
5. 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.

2. Using a modeling knife, cut one length of silicon
fuel line (the length of silicon fuel line is
calculated by how the weighted clunk should
rest about 5mm away from the rear of the tank
and move freely inside the tank). Connect one
end of the line to the weighted clunk and the
other end to the nylon pick up tube in the
stopper.
3. Carefully bend the second nylon tube up at a 45
degree angle (using a cigarette lighter). This
tube will be the vent tube to the muffler.
4. Carefully bend the third nylon tube down at a 45
degree angle (using a cigarette lighter). This
tube will be vent tube to the fueling valve.
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.
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.
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.
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.

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.

3. Slide the adjustable metal connector / servo arm
assembly over the plain end of the pushrod wire.
Position the throttle stick and the throttle trim at
their lowest positions.
4. Manually push the carburator barrel fully closed.
Angle the arm back about 45 degree from center
and attach the servo arm onto the servo. With the
carburator barrel fully closed, tighte the set screw
in the adjustable metal connector.
5. Remove the excess throttle pushrod wire using
wire cutters and install the servo arm retaining
screw.
!
INSTALLING THE THROTTLE
1. Install one adjustable metal connector through
the third hole out from the center of one servo
arm, enlarge the hole in the servo arm using a
2mm drill bit to accommodate the servo
connector. Remove the excess material from
the arm.
After installing the adjustable metal connector
apply a small drop of thin C/A to the bottom nut.
This will prevent the connector from loosening
during flight.
2. Plug the throttle servo into the receiver and turn on
the radio system. Check to ensure that the throttle
servo output shaft is moving in the correct
direction. When the throttle stick is moved forward
from idle to full throttle, the throttle barrel should
also open and close using this motion. If not,
reverse the direction of the servo, using the
transmitter.
Apply threadlocker (screw cement).

MOUNTING THE COWL
1. Remove the muffler and needle valve assembly
from the engine. Slide the fiberglass cowl over the
engine.
2. Measure and mark the locations to be cut out for
engine head clearance, needle valve, muffler.
Remove the cowl and make these cutouts using a
rotary tool with a cutting disc and a rotary sanding
drum attachment.
3. Slide the cowl back into place. 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 the middle of the precut opening. Hold the cowl
firmly in place using several pieces of masking
tape.
Enlarging the holes through the cowl will prevent
the fiberglass from splitting when the mounting
screws are installed.
6. Slide the cowl back over the engine and secure it
in place using four screws.
7. Install the muffler. Connect the fuel and pressure
lines to the carburator, muffler and fuel filler
valve. Tighten the screws completely.
!
4. While holding the cowl firmly in position, drill
four 1,6mm pilot holes through both the cowl
and the side edges of the firewall.
5. Using a 3mm drill bit, enlarge the four holes in
the cowling.

INSTALLING THE SWITCH
1. The switch should be mounted on the fuselage
side, opposite the muffler, close enough to the
receiver so the lead will reach. Use the face plate
of the switch cut out and locate the mounting
holes.
2. Cut out the switch hole using a modeling knife.
Use a 2mm drill bit and drill out the two mounting
holes through the fuselage side.
3. Secure the switch in place using the two machine
screws provided with the radio system.
!
INSTALLING THE RECEIVER AND BATTERY
1. Plug the servo leads and the switch lead into the
receiver. You 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.
Do not permanently secure the receiver and battery
until after balancing the model.
INSTALLING THE SPINNER
Install the spinner back-plate, propeller and
spinner cone. The spinner cone is held in place
using two screws.
The propeller should not touch any part of the
spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.

3. Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane.
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery pack
further back in the fuselage. If this is not possible
or does not correct it, stick small amounts of lead
weight on the fuselage under the horizontal
stabilizer. If the tail of the plane falls, the plane is
tail heavy. To correct this, move the battery and
receiver forward or if this is not possible, stick
weight into the firewall. When balanced correctly,
the airplane should sit level or slightly nose down
when you lift it up with your fingers.
BALANCING
1. It is critical that your airplane be balanced correctly.
Improper balance will cause your plane to lose
control and crash.

transmitter and check that the control
surfaces move freely and in the
CORRECT directions.
ALWAYS land the model INTO the
wind, this ensures that the model lands
at the slowest possible speed.
Switch on the transmitter.
Switch off the transmitter.
Check that the transmitter batteries
have adequate power.
Switch off the receiver.
Switch on the receiver.
ALWAYS take off into the wind.
Check that the wings are correctly
fitted to the fuselage.
