1. Install the rubber grommets and brass eyelets

onto the aileron servo.

2. Using a modeling knife, remove the covering

from over the pre-cut servo arm exit hole on the

aileron servo tray / hatch. This hole will allow

the servo arm to pass through when installing

the aileron pushrods.

3. Place the servo into the servo tray. Center the

servo within the tray and drill pilot holes

through the block of wood for each of the four

mounting screws provided with the servo.

4. Using the thread as a guide and using masking

tape, tape the servo lead to the end of the

thread: carefully pull the thread out. When you

have pulled the servo lead out, remove the

masking tape and the servo lead from the

thread.

5. Place the aileron servo tray / hatch into the

servo box on the bottom of the wing and drill

pilot holes through the tray and the servo box

for each of the four mounting screws. Secure

the servo tray in place using the mounting

screws provided .

6. Repeat step # 2 - # 5 to install the second

aileron servo in the opposite wing half.

Make certain the hinges are adequately secured with glue. If

they come loose in flight accidents may result.

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

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.

INSTALLING THE AILERONS

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.

6. When you are sure that everything is aligned

correctly, mix up a generous amount of 30 minute

epoxy. Apply a thin layer to the top and bottom of

the stabilizer mounting area and to the stabilizer

mounting platform sides in the fuselage. Slide

the stabilizer in place and re-align. Double check

all of your measurements one more time before

the epoxy cures. Remove any excess epoxy using

a paper towel and rubbing alcohol and hold the

stabilizer in place with T-pins or masking tape.

7. After the epoxy has fully cured, remove the

masking tape or T-pins used to hold the stabilizer

in place and carefully inspect the glue joints. Use

more epoxy to fill in any gaps that were not filled

previously and clean up the excess using a paper

towel and rubbing alcohol.

8. Installing the elevator using C.A glue as installing

the aileron.

HORIZONTAL STABILIZER INSTALLATION

1. Using a modeling knife, cut away the covering

from the fuselage for the stabilizer and remove it.

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.

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.

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.

CONTROL THROWS

LATERAL BALANCE

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.

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 65mm

(2.6 in) BACK FROM THE LEADING EDGE OF

THE WING, AT THE FUSELAGE. BALANCE A

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.

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.

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.

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 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.

INSTALLING THE Fuel 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.

9. Secure the fuel tank.
