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
aircraftand toprotect thetable. Keepa 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
havethe correctpartsandthatthey fitand are
alignedproperly beforegluing!This willassure
properassembly.SPITFIRE ARFis handmade
from natural materials, every plane is unique
andminor adjustmentsmayhavetobe 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

SAFETY PRECAUTION.
Caution: this model is not a toy!
If you are a beginner to this type of powered
model,please askanexperiencedmodelflyer
forhelp andsupport. Ifyou attemptto operate
themodel withoutknowingwhat youaredoing
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
Evenifyou havealready built alarge number
ofRC modelsplease readrightthroughthese
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: Blowwarm airoverthe 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
bebuiltinaveryshorttime. However, thework
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.

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.
INSTALLING THE STOPPER ASSEMBLY
1) The stopper has been pre-assembled
at the factory.
2) Using a modeling knife, cut one length
ofsilicon fuelline (thelength ofsilicon fuelline
iscalculatedbyhow theweightedclunk should
restabout 8mmaway fromthe rearof thetank
andmove freelyinside thetank). Connectone
FUEL TANK.
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.
5) Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using
amodeling knife. Ifflashing is present, make
sure none of it falls into the tank.
6) Whensatisfied withthe alignmentof 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.
4) Carefullybend thethirdnylon tubedown
ata 45degreeangle (usingacigarette lighter).
This tubewill bevent tubetothefuelingvalve.
Blow through one of the lines to ensure
the fuel lines have not become kinked inside
the fuel tank compartment. Air should flow
througheasily.
9) Tosecure the fueltank inplace, apply a
bead of silicon sealer to the forward area of
thetank, whereitexitsthefuselage behindthe
enginemountingbox andtotherear ofthe tank
at the forward bulkhead.
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 frontofthe tankshould justabout
touch the back of the firewall.
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
