This instruction manual is designed to help you build a great ying aeroplane. Please read this manual thoroughly
before starting assembly of your SPITFIRE MK. Use the parts listing below to identify all parts.
Please trial fit all the parts. Make sure you have
the correct parts and that they t and are aligned
properly before gluing! This will assure proper
assembly. SPITFIRE MK 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.
FUSELAGE ASSEMBLY
(1) Fuselage.
WING ASSEMBLY
(1) Right wing half with pre-installed aileron.
(1) Left wing half with pre-installed aileron.
TAIL SECTION ASSEMBLY
(1) Vertical stabilizer with pre-installed rudder.
(1) Horizontal stabilizer with pre-installed
elevator halves.
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.
SUGGESTION
NOTE

REPLACEMENT LARGE PARTS
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 y 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 t the screw.
Caution: This model is not a toy!
If you are a beginner to this type of powered model,
please ask an experienced model yer 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 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 lm covering
Minor creases or bubbles may develop in the lm
covering due to major uctuations in weather conditions
(temperature, humidity etc.); in rare cases you may
even nd a slight warp in a component. These minor
faults are in the nature of lm-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 wrap: Hold the panel twisted gently in
the opposite direction to the wrap,and
apply warm air to remove the creases
from the covering.
Caution! do not heat the lm more than is absolutely
necessary. If the air or the iron is too hot, the lm may
melt and holes may be formed.
+ This is not a toy.
+ Be sure that no other yers 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 ip the propeller with your ngers.
+ 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.

Locate the long piece of wire used for the throttle
pushrod. One end of the wire has been pre-bend in to a
“Z” bend at the factory. This “Z” bend should be inserted
into the throttle arm of the engine when the engine is
tted onto the engine mount. Fit the engine to the engine
mount using the screws provided.

1. 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 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 mufer.
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.
When the stopper assembly is installed in the tank, the
top of the vent tube should rest just below the top sur-
face of the tank. It should not touch the top of the tank.
VII. FUEL TANK
VI. SERVOS INSTALLATION
INSTALLING THE FUSELAGE SERVOS
1) Install the rubber grommets and brass collets
into the elevator, rudder and throttle servos. Test t
the servos into the servo tray. Trim the tray if neces-
sary to t your servos.
2) Mount the servo to the tray using the mounting
screws provided with your radio system.

5mm
5) Test t the stopper assembly into the tank. It may
be necessary to remove some of the ashing around
the tank opening using a modeling knife. If ashing is
present, make sure none of it falls into the tank.
6) When satised 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 compart-
ment and through the pre-drilled hole in the rewall. 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 rewall.
Blow through one of the lines to ensure the fuel
lines have not become kinked inside the fuel tank
compartment. Air should ow 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 battery in the fuel tank compartment.

Pushrod wire
Install one adjustable metal connector through the third
hole out from the center of one servo arm, enlarge the
hole in the servo arm using a 2mm drill bit to accommo-
date the servo connector. Remove the excess material
from the arm.
After installing the adjustable metal connector apply
a small drop of thin C/A to the bottom nut. This will
prevent the connector from loosening during ight.
2. INSTALLING THE THROTTLE PUSHROD
VIII. COWLING
1) Slide the berglass cowl over the engine and
line up the back edge of the cowl with the marks you
made on the fuselage.
2) While keeping the back edge of the cowl ush
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 rmly in place using
pieces of masking tape.
3) Slide the cowl back over the engine and secure
it in place using four wood screws. See picture below.
4) Install the mufer and mufer extension onto
the engine and make the cutout in the cowl for mufer
clearance. Connect the fuel and pressure lines to the
carburetor, mufer and fuel ller valve.
Drill four 2.5mm pilot holes through both the cowl and
the side edges of the rewall.
Using a 3mm drill bit, enlarge the four holes in the
cowling.
