I/C FLIGHT WARNINGS
Always operate in open areas, away
from factories, hospitals, schools,
buildings and houses etc. NEVER fly
your aircraft close to people or built
up areas.
THE PROPELLER IS DANGEROUS
Keep fingers, clothing (ties, shirt
sleeves, scarves) or any other loose
objects that could be caught or drawn
in, away from the propeller. Take care
at ALL times.
Keep all onlookers (especially small
children and animals) well back from
the area of operation. This is a flying
aircraft, which will cause serious
injury in case of impact with a person
or animal.
NEVER fly near power lines, aerials
or other dangerous areas including
airports, motorways etc.
NEVER use damaged or deformed
propellers or spinners.
DO NOT dispose of empty fuel
containers on a fire, this can lead to
an explosion.
NEVER fly in wet conditions or on
windy or stormy days.
ALWAYS adjust the engine from
behind the propeller, and do not allow
any part of your body to be in line
with the propeller.

I/C FLIGHT GUIDELINES
Made in Vietnam
When ready to fly, first extend the
transmitter aerial.
Operate the control sticks on the
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.
If the model does not respond correctly
to the controls, land it as soon as
possible and correct the fault.
Empty the fuel tank after flying, fuel left
in the tank can cause corrosion and
lead to engine problems.

INSTALLING THE STOPPER ASSEMBLY
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.
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.
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.

2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 155mm back from the
leading edge, at the fuselage sides.
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.
THE CENTER OF GRAVITY IS LOCATED
155mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE.
!
CONTROL THROWS
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.
LATERAL BALANCE
After you have balanced a plane on the C.G.
You should laterally balance it. Doing this will
help the airplane track straighter.
1. Turn the airplane upside down. Attach one 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.

TOOLS AND SUPPLIES NEEDED
• Medium C/A glue
• 30 minute epoxy
• 6 minute epoxy
• Hand or electric drill
• Assorted drill bits
• Modeling knife
• Straight edge ruler
SUGGESTION
To avoid scratching your new airplane, do not unwrap
the pieces until they are needed for assembly. Cover
your workbench with an old towel or brown paper,
both to protect the aircraft and to protect the table.
Keep a couple of jars or bowls handy to hold the
small parts after you open the bag.
NOTE:
1. Please trial fit all the parts. Make sure you have
the correct parts and that they fit and are aligned
properly before gluing! This will assure proper
assembly. The LA9 size 25cc-35cc is hand made
from natural materials, every plane is unique and
minor adjustments may have to be made.
However, you should find the fit superior and
assembly simple.
2. The painted and plastic parts used in this kit are
fuel proof. However, they are not tolerant of many
harsh chemicals including the following: paint
thinner, C/A glue accelerator, C/A glue debonder
and acetone. Do not let these chemicals come in
contact with the colors on the covering and the
plastic parts.
SAFETY PRECAUTION:
• This is not a toy.
• Be sure that no other flyers are using your radio
frequency.
• Do not smoke near fuel.
• Store fuel in a cool, dry place, away from
children and pets.
• Wear safety glasses.
• The glow plug clip must be securely attached to
the glow plug.
• Do not flip the propeller with your fingers.
• Keep loose clothing and wires away from the
propeller.
• Do not start the engine if people are near. Do not
stand in line with the side of the propeller.
• Make engine adjustments from behind the
propeller only. Do not reach around the spinning
propeller.
• 2 bender plier
• Wire cutters
• Masking tape
• Thread lock
• Paper towels
• Rubbing alcohol
PREPARATIONS
Remove the tape and separate the ailerons
from the wing and the elevators from the stab.
Use a covering iron with a covering sock on
high heat to tighten the covering if necessary.
Apply pressure over sheeted areas to
thoroughly bond the covering to the wood.

MOUNTING THE COWL
1. Measure and mark the locations to be cut out
for engine head clearance, needle valve,
muffler. Remove the cowl and make these cut
outs using a rotary tool with a cutting disc and a
rotary sanding drum attachment.
2. 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.
3. While holding the cowl firmly in position, drill
four 1,6mm pilot holes through both the cowl
and the side edges of the firewall.
4.
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.
5. Slide the cowl back over the engine and secure
it in place using four 3mm x 12mm wood
screws.
