INTRODUCTION.
Thankyouforchoosingthe SPITFIRE2030mmARTFbySEAGULLMODELSCOMPANY LTD.The
SPITFIRE was designed with the intermediate/advanced sport flyer in mind. It is a semi scale
airplane which is easy to fly and quick to assemble. The airframe is conventionally built using balsa,
plywood to make it stronger than the average ARTF , yet the design allows the aeroplane to be kept
light. You will find that most of the work has been done for you already.The motor mount has been
fitted and the hinges are pre-installed . Flying the SPITFIRE is simply a joy.
This instruction manual is designed to help you build a great flying aeroplane. Please read this
manual thoroughly before starting assembly of your SPITFIRE . 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.

into the aileron servo mount.
2) Secure the servos with the screws pro-
vided with your radio system.
Because the size of servos differ, you may
need to adjust the size of the precut opening
in the mount. The notch in the sides of the
mount allow the servo lead to pass through.

of silicon fuel line. Connect one end of the line
to the weighted fuel pick up and the other end
to the nylon pick up tube.
1) Using a modeling knife, carefully cut
off the rear portion of one of the 3 nylon tubes
leaving 1/2” protruding from the rear of the
stopper. This will be the fuel pick up tube.

6) When satisfied with the alignment of
the stopper assembly tighten the 3 x 20mm
machine screw until the rubber stopper ex-
pands and seals the tank opening. Do not
overtighten the assembly as this could cause
the tank to split.
You should mark which tube is the vent
and which is the fuel pickup when you
attach fuel tubing to the tubes in the stopper.
Once the tank is installed inside the fuselage,
it may be difficult to determine which is which.
Fuel tank.
FUEL TANK INSTALLATION.
7) Slide the fuel tank into the fuselage. Guide
the lines from the tank through the hole in the
firewall .
4) 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 falls into the tank.
5) With the stopper assembly in place,
the weighted pick-up should rest away from
the rear of the tank and move freely inside the
tank. The top of the vent tube should rest just
below the top of the tank. It should not touch
the top of the tank.

and muffler. The vent line will connect to the
muffler and the line from the clunk to the
carburetor.
ENGINE MOUNT INSTALLATION.
1) Locate the items necessary to install the
engine mount included with your model. .
2) Use low-tack tape to secure the plywood
engine template to the firewall, making sure it
is centered. Use a drill and 1/16 inch (1.5mm)
drill bit to drill the four pilot holes for the wood
box mounting screws.

2) Use a pin drill and 4mm drill bit to drill a
small indentation in the mount for the engine
mounting screw.
5) Slide the pushrod tube in the firewall and
guide it through the fuel tank mount. Use
medium C/A to glue the tube to the firewall and
the fuel tank mount.
6) Connect the Z-bend in the 600mm throttle
pushrod to the outer hole of the carburetor arm.
3) Use a drill to drill the four holes in the engine
mount rails.

marks you made on the fuselage then trim and
cut as shown.
8) Reinstall the servo horn by sliding the
connector over the pushrod wire. Center the
throttle stick and trim and install the servo horn
perpendicular to the servo center line.
9) Move the throttle stick to the closed position
and move the carburetor to closed. Use a 2.5mm
hex wrench to tighten the screw that secures
the throttle pushrod wire. Make sure to use
threadlock on the screw so it does not vibrate
loose.
Secure the ignition module in the fuselage
using hood and loop tape. Route the wires as
neccessary, making sure to connect the lead
from the ignition switch and the sensor from
the engine. The lead for the plug is routed
through the opening in the firewall.
Pass the lead for the ignition through the
rectangular hole in the firewall. Connect to the
corresponding lead from the ignition module.
