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
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

INSTALLING THE SPINNER
Install the spinner back-plate, propeller and
spinner cone. The spinner cone is held in place
using two 3mm x 20mm wood 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.
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.
3. Strap the battery pack and receiver onto the
wing joiner tube in the fuselage.
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.
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.

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.
NEVER fly near power lines, aerials
or other dangerous areas including
airports, motorways etc.
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.

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
110mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying
and trimming. There is a 5mm margin forward
and aft. 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 110mm 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.
FLIGHT PREPARATION
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.
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.
5. 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.
6. 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.

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
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.
