This instruction manual is designed to help you build a great flying aeroplane. Please read this
manual thoroughly before starting assembly of your CORSAIR. Use the parts listing below to identify
all parts.

WARNING

Please be aware that this aeroplane is not a toy and if assembled or used incorrectly it is
capable of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU
ASSUME ALL RISK & RESPONSIBILITY.

If you are inexperienced with basic R/C flight we strongly recommend you contact your R/C supplier
and join your local R/C Model Flying Club. R/C Model Flying Clubs offer a variety of training
procedures designed to help the new pilot on his way to successful R/C flight. They will also be able
to advise on any insurance and safety regulations that may apply.

T o 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.

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 .

CORSAIR ARF 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.

Caution: this model is not a toy!
If you are a beginner to this type of powered
model, please ask an experienced model flyer
for help and support. If you attempt to operate
the model without knowing what you are doing
you could easily injure yourself or somebody
else. Please keep your safety and well-being
in mind at all times.

Important: before you start construction
Even if you have already built a large number
of RC models please read right through these
instructions and check all the kit components
against the parts list. We have taken great
trouble to keep construction as simple as
possible, without making any compromises
in the area of safety .

Note regarding the film covering

Minor creases or bubbles may develop in the
film covering due to major fluctuations in
weather conditions (temperature, humidity
etc.); in rare cases you may even find a slight
warp in a component. These minor faults are
in the nature of film-covered built-up wooden
structures, and can easily be corrected using
a heat gun, as commonly used for modelling.
Creases: Blow warm air over the area

and rub down with a soft
cloth.

Wing warp: Hold the panel twisted

gently in the opposite
direction to the warp, and
apply warm air to remove
the creases from the
covering.

Caution! do not heat the film more than is
absolutely necessary. If the air or the iron is
too hot, the film may melt and holes may be
formed.

This model is highly pre-fabricated and can
be built in a very short time. However, the work
which you have to carry out is important and
must be done carefully. The model will only
be strong and fly well if you complete your
tasks competently - so please work slowly
and accurately.

When self-tapping screws have to be
screwed into wood, apply a little white
glue to prevent them shaking loose: just
squirt white glue into the hole and fit the
screw.

+ 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.

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.



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.



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.

 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.

other end to the nylon pick up tube in the stop­per.

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.



9) T o secure the fuel t ank 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.

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

1) It is critical that your airplane be bal-

anced correctly . Improper balance will cause
your plane to lose control and crash.

THE CENTER OF GRAVITY IS LOCATED
130MM BACK FROM THE LEADING EDGE
OF THE WING .



2) Mount the wing to the fuselage. Using a

couple of pieces of masking tape, place them
on the top side of the wing 130mm 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 .

Rudder : 20mm right 20mm left



1) We highly recommend setting up a

plane using the control throws listed.



2) The control throws should be meas-

ured at the widest point of each control sur­face.



3) Check to be sure the control surfaces

move in the correct directions.

CONTROL THROWS.

*If possible, first attempt to balance the model
by changing the position of the receiver bat­tery and receiver. If you are unable to obtain
good balance by doing so, then it will be nec­essary to add weight to the nose or tail to
achieve the proper balance point.

With the wing attached to the fuselage, all
parts of the model installed ( ready to fly), and
empty fuel tanks, hold the model at the
marked balance point with the stabilizer level.

Lift the model. If the tail drops when you
lift, the model is “tail heavy” and you must
add weigh* to the nose. If the nose drops, it
is “nose heavy” and you must add weight* to
the tail to balance.

Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located 130mm back from the
leading edge. This is the balance point at which
your model should balance for your first flights.
Later, you may wish to experiment by shifting
the balance up to 10mm forward or back to
change the flying characteristics. Moving the
balance forward may improve the smooth­ness and arrow- like tracking, but it may then
require more speed for take off and make it
more difficult to slow down for landing. Moving
the balance aft makes the model more agile
with a lighter and snappier ”feel”. In any case,
please start at the location we recommend .

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.
