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.

INSTALLING THE HORIZONTAL STABILIZER

1. Using a modeling knife, cut away the covering from

the fuselage for the stabilizer and remove it.

5. Remove the stabilizer. Using the lines you just

drew as a guide, carefully remove the covering

from between them using a modeling knife.

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. Attach the wing to the fuselage and test the

position of the elevator and adjust it as shown.

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.

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.

INSTALLING THE THROTTLE

1. Install one adjustable metal connector through

the third hole out from the center of one servo

arm, enlarge the hole in the servo arm using a

2mm drill bit to accommodate the servo

connector. Remove the excess material from

the arm.

After installing the adjustable metal connector

apply a small drop of thin C/A to the bottom nut.

This will prevent the connector from loosening

during flight.

12. With the elevator halves and elevator servo

centered, carefully place a mark on the

elevator pushrod wire where it crosses the

hole in the servo arm.

13. Using pliers, carefully make a 90 degree bend

up at the mark made. Cut off the excess wire,

leaving about 8mm beyond the bend.

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

fuselage.

11. Be sure both elevator halves are flat. Center

both elevator halves and hold them in place

using a couple of pieces of masking tape.

INSTALLING THE RUDDER PUSHROD

1. Locate the pushrod exit slot on the right side of

the fuselage.

2. Carefully cut away the covering material from

the slot.

3. Working from inside the fuselage, slide the

threaded end of the remaining pushrod down

the inside of the fuselage until the pushrod

reaches the exit slot. Carefully reach in with a

small screw driver and guide the pushrod out of

the exit slot.

4. Install the clevis on the rudder pushrod. Make

sure 6mm of thread shows inside the clevis.

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.

7. Attach clevis to the third hole in the control

horn. Install a silicone tube on the clevis.

INSTALLING THE ELEVATOR PUSHROD

1. Locate the pushrod exit slot on the right side

and left side of the fuselage. It is located

slightly ahead and below the horizontal

stabilizer.

2. Carefully cut away the covering material from

the slot.

3. Slide the pushrod housing through the hole in

the firewall, through the hole in the forward

bulkhead, and into the servo compartment.

4. Apply a couple of drops of thin C/A to the

pushrod housing where it exits the firewall and

where it passes through the forward bulkhead.

This will secure the housing in place.

5. Using a modeling knife, cut off the nylon

pushrod housing in front of the servo tray.

If your engine is equipped with a remote needle

valve, we suggest installing it into the engine at

this time.

INSTALLING THE ENGINE

Locate the long piece of wire used for the throttle

pushrod. One end of the wire has been

pre-bend in to a "Z" bend at the factory. This

"Z" bend should be inserted into the throttle

arm of the engine when the engine is fitted

onto the engine mount. Fit the engine to the

engine mount using the screws provided.

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. To secure the fuel tank in place, apply a bead of

silicon sealer to the forward area of the tank,

where it exits the fuselage behind the engine

mounting box and to the rear of the tank at the

forward bulkhead.

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. 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.

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.

6. Slide the cowl back over the engine and secure

it in place using four 3mm x 12mm wood

screws.

7. Install the muffler. Connect the fuel and pressure

lines to the carburator, muffler and fuel filler

valve. Tighten the screws completely.

Remove the covering.

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.

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.

4) Insert the dihedral brace into one wing half up

to the centerline. Wipe off any excess epoxy that

may have squeezed out of the joint using paper

towels.

3) When satisfied with the fit of the dihedral brace

in each wing half, remove the brace .Mix equal

amounts of part A and part B 30 minute epoxy.

Coat all sides of the dihedral brace box and half of

the wing brace with the epoxy. Make sure to cover

the top and bottom as well as the sides. Use

enough epoxy to fill any gaps.

2) Test fit the dihedral brace into each wing half.

The brace should slide in easily up to the

centerline you drew. If it does not, use 220 grit

sandpaper with a sanding block and sand down

the edges and ends of the brace until the proper fit

is obtained.

Center line

5) Once the epoxy has cured, trial fit both wing

halves together.The center gribs should fit flush

together with little or no gaps existing. If gaps do

exist, use 220 Grit sandpaper and sand down the

high spots on the root ribs and the wing joiner until

the proper fit is obtainer.

6) To protect the covering from the epoxy used to

glue the wing halves together, carefully apply

masking tape around the edge of the root rip on the

top and bottom of each wing half.

7) Mix a generous amount of 30 minute epoxy.

Coat the exposed half of the dihedral brace, the

wing joiner box and both root ribs with epoxy. Slide

the two wing halves together and carefully align

them at the leading and trailing edges. Wipe away

any excess epoxy using paper towels. Use masking

tape wrapped around the center section to hold the

halves in place until the epoxy cures.

Wing Assembly

*Note* We highly recommend using 30 Minute

Epoxy over faster curing epoxies for several

reasons. First, slower curing epoxy is stronger. It

also providers more working time, allowing the

builder to properly align the parts. Using fast cure

epoxy when joining the wing halves could result in

the glue drying before the wing halves are aligned

properly, causing damage to the wing assembly.

Also, when joining the wing halves, the entire area

of both center ribs need to be joined completely

with no gaps existing. Not following these steps

carefully, may result in failure of the wing center

section during flight.

1) Locate the wing dihedral brace. Using a ruler,

locate it's center and place a mark. Draw a

vertical line at the mark just made .

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
