1) Working with the aileron linkage for now, thread
one nylon clevis at least 14 turns onto one of the
2mm x 180mm threaded wires.

2) Attach the clevis to the outer hole in the control
horn. Install a silicone tube on the clevis.

3) Locate one nylon servo arm, and using wire
cutters, remove all but one of the arms. Using a
2mm drill bit, enlarge the third hole out from the
center of the arm to accommodate the aileron
pushrod wire.

4) Plug the aileron servo into the receiver and
center the servo. Install the servo arm onto the
servo. The servo arm should be perpendicular to
the servo and point toward the middle of the wing.

5) Center the aileron and hold it in place using a
couple of pieces of masking tape.

6) With the aileron and aileron servo centered,
carefully place a mark on the aileron pushrod wire
where it crosses the hole in the servo arm.

7) Using pliers, carefully make a 90 degree bend
down at the mark made. Cut off the excess wire,
leaving about 6mm beyond the bend.

8) Insert the 90 degree bend down through the
hole in the servo arm. Install one nylon snap
keeper over the wire to secure it to the arm. Install
the servo arm retaining screw and remove the
masking tape from the aileron.

INSTALLING THE FUEL TANK.

1) The stopper has been pre-assembled at the
factory.

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 8mm 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.
Connect 2 lines to the 2 vent tubes and 1 line to the
fuel pickup tube in the stopper.

8) Fe ed thr ee li nes t hro ugh t he fue l ta nk
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.

9) Secure the fuel tank.

INSTALLING THE THROTTLE

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.

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.

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.

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.

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.

PLASTIC PARTS FOR FUSELAGE.

INSTALLING THE RECEIVER AND BATTERY.

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.

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.

BALANCING

1) It is critical that your airplane be balanced
correctly. Improper balance will cause your plane to
lose control and crash.

BACK FROM THE LEADING EDGE OF THE
WI NG. AT THE FU SE LA GE. BALANCE A

PLANE UPSIDE DOWN WITH THE FUEL
TANK EMPTY.

2) Mount the wing to the fuselage. Using a couple of
pieces of masking tape, place them on the top side of
the wing 85mm back from the leading edge, at the

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.

loop of heavy string to the engine crankshaft and
one to the tail wheel wire. With the wings level,
carefully lift the airplane by the string. This may
require two people to make it easier.

2) If one side of the wing fall, that side is heavier
than the opposite. Add small amounts of lead
weight to the bottom side of the lighter wing half's
wing tip. Follow this procedure until the wing stays
level when you lift the airplane.

1) We highly recommend setting up a plane using
the control throws listed.

2) The control throws should be measured at the
widest point of each control surface.

3) Check to be sure the control surfaces move in the
correct directions.

PRE-FLIGHT CHECK

1) Completely charge your transmitter and

receiver batteries before your first day of flying.

2) Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.

3) Double check the balance of the airplane.

4) Check the control surface.

5) Check the receiver antenna. It should be fully

extended and not coiled up inside the fuselage.

6) Properly balance the propeller.
