SUGGESTION.
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
aircraft and to protect the table. Keep a couple
of jars or bowls handy to hold the small parts
after you open the bag.
NOTE.
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. P-47 THUNDERBOLT 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.
P47 - THUNDERBOLT.
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.
SAFETY PRECAUTION.
+ 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.

not included.
FUEL TANK.
INSTALLING THE ST OPPER 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 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.

 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 t ank comp artment. 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.

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 GRA VITY IS LOCA TED
90mm 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 90 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 located90 mm 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 .
 3. Turn the airplane up side down. Place
your fingers on the masking tape and carefully
lift the plane .
 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
achieve the proper balance point.

INSTRUCTION MANUAL.
 1) We highly recommend setting up a
plane using the control throws listed.
 2) The control throws should be measured at the widest point of each control surface.
 3) Check to be sure the control surfaces
move in the correct directions.

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.
We wish you many safe and
enjoyable flights with
your P47-THUNDERBOLT.
