CHIPMUNK ITEM CODE: BH63-A . 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 CHIPMUNK. 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.

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. CHIPMUNK 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 su-
perior 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.

CHIPMUNK ITEM CODE: BH63-A . 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.
SAFETY PRECAUTION.

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.
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

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 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.
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.
 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
