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.

FINAL ASSEMBLY
INSTALLING THE SPINNER
Install the spinner back-plate, propeller and
spinner cone. The spinner cone is held in place
using two 3mm x 12mm 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.
!
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.

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.
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.
5. Remove the excess throttle pushrod wire using
wire cutters and install the servo arm retaining
screw.
!
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.
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.
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.
!
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. 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

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
65-70mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 65-70mm 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 heavy
nose. 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.
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.
65-70mm
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.

Aileron Control
CONTROL THROWS
1. We highly recommend setting up a plane using
the control throws listed.
2. The control throws should be measured at the

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.

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.
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 .

INSTALLING THE ENGINE
1. Install the engine mount to the fuselage.
2. 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.
7. Locate the nose gear wire. Slide the nose gear
wire up through the lower portion of the nose
gear block, then through the nylon steering arm,
then through the upper portion of the nose gear
block. The top of the nose gear wire should be
flush with the top of the nose gear bracket.
8. With the nose gear wire straight, angle the nylon
steering arm about 30
0
forward of the fire-wall
and tighten the set screw. Angling the arm
forward like this will allow room for the arm to
move back for more adequate steering.
9. Install the remaining wheel onto the axle using
the two wheel collars and set screws provided.
The wheel should be centered on the axle with
a wheel collar on each side, holding it in place.
Tighten the set screws on the collars to secure
them in place. The wheel should rotate freely.
You should apply a small drop of Lock_tite
thread lock to each set screw to prevent them
from coming loose.
