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.

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.

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.

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.

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.
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 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.
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 permanently until after balancing the airplane. You
may need to remove the tank to mount the

3. Turn the airplane upside down. Place
your fingers on the masking tape and carefully lift the plane .
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
125MM 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 125 mm back from
the leading edge, at the fuselage sides.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located 125mm 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 .
BALANCING.
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.
*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
ac h ieve the prop er balan ce poi nt.

INSTRUCTION MANUAL
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.
PRE-FLIGHT CHECK.
We wish you many safe and enjoyable
flights with your CHIPMUNK.
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.
