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
K8B 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.
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.

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.
1
INSTALLING THE AILERONS
1. Use the modeling knife to cut a strip of covering
from the hinge slots in the wing and aileron.
2. Locate the four CA hinge strip. Snip off the
corners so they go in easier.
3. Test fit the ailerons to the wing with the hinges.
If the hinges don’t remain centered, stick a pin
through the middle of the hinge to hold it in
position.

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. 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.
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.

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 80mm
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 80mm 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.
80mm
!
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.
Open and close the canopy

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.
Aileron : 10mm up 10mm down
Elevator : 8mm up 8mm down

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.

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.
