CORSAIR - Item code: BH77 . Instruction Manual
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.
TOOLS & SUPPLIES NEEDED
1Thick cyanoacrylate glue.
130 minute epoxy.
15 minute epoxy.
1Hand or electric drill.
1Assorted drill bits.
1Modelling knife.
1Straight edge ruler.
12mm ball driver.
1Phillips head screwdriver.
1220 grit sandpaper.
190° square or builder’s triangle.
1Wire cutters.
1Masking tape & T-pins.
1Thread-lock.
1Paper towels.
Some more parts.

COWLING.
Landing gear.....
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 air-
craft and to protect the table. Keep a couple of
jars or bowls handy to hold the small parts af-
ter 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 follow-
ing: paint thinner, C/A glue accelerator, C/A glue
debonder and acetone. Do not let these chemi-
cals come in contact with the colors on the
covering and the plastic parts.

CORSAIR - Item code: BH77 . Instruction Manual
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.

out from the center of the arm to accommo-
date the aileron pushrod wire.
5. Using pliers, carefully make a 90 degree
bend down at the mark made. Cut off the ex-

pre-bend in to a “Z” bend at the factory . This
“Z” bend should be inserted into the throttle

INSTALLING THE STOPPER ASSEMBLY
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 8mm 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 stop-
per.
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.

CORSAIR - Item code: BH77 . Instruction Manual
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.
6) When satisfied with the alignment of the
stopper assembly tighten the 3mm x 20mm
machine screw until the rubber stopper ex-
pands 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.
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.
Secure
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 t ank compartment. Air should flow
through easily.
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.
Do not secure the tank into place perma-
nently until after balancing the airplane.
You may need to remove the tank to mount
the battery in the fuel tank compartment.

1) Slide the fiberglass cowl over the engine
and line up the back edge of the cowl with the
marks you made on the fuselage.
3) Slide the cowl back over the engine
and secure it in place using four wood screws.
See picture below.
2) While keeping the back edge of the
cowl flush with the marks, 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 nearly the middle of the cowl
opening. Hold the cowl firmly in place using
pieces of masking tape.
4) Install the muffler and muffler extension
onto the engine and make the cutout in the
cowl for muffler clearance. Connect the fuel
and pressure lines to the carburetor , muffler
and fuel filler valve.
