INTRODUCTION.
Thankyouforchoosingthe SWIFT40 ARTFbySEAGULLMODELS.TheSWIFT 40 wasdesigned
with the sports trainer flyer in mind. It is a High-wing aeroplane which is easy to fly and quick to
assemble.Theairframeisconventionally built using balsa, plywood andveneertomakeitstronger
thantheaverageARTF,yetthedesign allows the aeroplane to be kept light. You willfindthatmost
of the work has been done for you already. The pushrods are pre-made to the correct lengths, the
motor mount has been fitted and the hinges are pre-installed and pinned for security. Flying the
SWIFT40 is simply a joy.

2)Removeeachhinge from thewingpanel
and aileron and place a T-pin in the center of
each hinge. Slide each hinge into the wing
panel until the T-pin is snug against the wing
panel. This will help ensure an equal amount
ofhingeis on eithersideofthe hinge linewhen
the aileron is mounted to the aileron.
The control surfaces, including the
ailerons, elevators, and rudder, are
prehinged with hinges installed, but the
hinges are not glued in place. It is
imperativethatyouproperlyadherethe

4) Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
aileronsfrontsurface should lightlycontactthe
wing during this procedure. Ideally, when the
hinges are glued in place, a 1/64” gap or less
will be maintained throughout the lengh of the
aileron to the wing panel hinge line.
Thehingeis constructedofa special
material that allows the C/A to wick

WING ASSEMBLY.
8)Afterboth ailerons are securely hinged,
firmly grasp the wing panel and aileron to
make sure the hinges are securely glued and
cannot be pulled out. Do this by carefully
applying medium pressure, trying to separate
the aileron from the wing panel. Use caution
not to crush the wing structure.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
6) Using C/A remover/debonder and a
papertowel,removeanyexcess C/A glue that
may have accumulated on the wing or in the
aileronhingearea.
5)Turn the wing paneloveranddeflectthe
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge,making surethatthe C/Apenetratesinto
both the aileron and wing panel.
Workthe aileronupand downseveral
times to “work in” the hinges and
check for proper movement.
Note:
HINGING THE ELEVATOR.
Glue the elevator hinges in place using the
same techniques used to hinge the ailerons.
HINGING THE RUDDER.
Glue the rudder hinges in place using the
same techniques used to hinge the ailerons.

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 GRAVITY IS LOCATED
65 MM BACK FROM THE LEADING EDGE
OF THE WINGAT THE WING ROOT.
 3) Turn the airplane upside down. Place
yourfingersonthe masking tape and carefully
lift the plane .
 2)Mountthewingtothefuselage.Using a
couple of pieces of masking tape, place them
on the top side of the wing 65 mm back from
the leading edge of the wing at the wing root.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located 65 mm back from the
leadingedgeofthewingat thewing root. This
is the balance point at which your model
should balance for your first flights. Later, you
maywishto experimentbyshiftingthe 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
alighter andsnappier”feel”.Inany case,please
start at the location we recommend .
Withthewingattachedtothefuselage,allparts
ofthemodelinstalled ( readytofly),andempty
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
weight* to the nose. If the nose drops, it is
“noseheavy” and you must add weight* to the
tail to balance.
M4x20mm.

19
Instruction Manual.
E) Check the throttle. Moving the
throttle stick forward should open the carbu-
retor barrel. If it does not, flip the servo re-
versing switch on your transmitter to change
the direction.
D) Check the rudder. Looking from
behind the airplane, move the rudder stick to
theright. Theruddershouldmove to the right.
Ifitdoesnot,fliptheservoreversing switch on
your transmitter to change the direction.
F) From behind the airplane, look at
the aileron on the right wing half. Move the
aileron stick to the right. The right aileron
should move up and the other aileron should
move down. If it does not, flip the servo re-
versing switch on your transmitter to change
the direction.
PREFLIGHT CHECK.
1) Completely charge your transmitter
and receiver batteries before your first day of
flying.
2) Check every bolt and every glue joint
in the SWIFT40 to ensure that everything is
tight and well bonded.
3) Double check the balance of the air-
plane. Do this with the fuel tank empty.
4) Checkthecontrolsurfaces. Allshould
move in the correct direction and not bind in
any way.
5) If your radio transmitter is equipped
withdualrateswitchesdoublecheckthatthey
are on the low rate setting for your first few
flights.
6) Check to ensure the control surfaces
are moving the proper amount for both low
and high rate settings.
7) Check the receiver antenna. It should
be fully extended and not coiled up inside the
fuselage.
8) Properlybalancethepropeller. An out
of balance propeller will cause excessive vi-
bration which could lead to engine and/or air-
frame failure.
We wish you many safe and enjoyable
flights with your SWIFT40.
