SWIFT40. Instruction Manual.
INTRODUCTION.
Thank you for choosing the SWIFT40 ARTF by SEAGULL MODELS. The SWIFT 40 was designed
with the sports trainer flyer in mind. It is a High-wing aeroplane which is easy to fly and quick to
assemble. The airframe is conventionally built using balsa, plywood and veneer 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 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.
This instruction manual is designed to help you build a great flying aeroplane. Please read this
manual throughly before starting assembly of your SWIFT40 . 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.

2) Remove each hinge from the wing panel
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
of hinge is on either side of the hinge line when
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
imperative that you properly adhere the
hinges in place per the steps that follow
using a high-quality thin C/A glue.
Note:
HINGING THE AILERONS.
Hinge.
3) Slide the wing panel on the aileron until
there is only a slight gap. The hinge is now
centered on the wing panel and aileron.
Remove the T-pins and snug the aileron
against the wing panel. A gap of 1/64” or less
should be maintained between the wing panel
and aileron.
1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
C/A glue.
4) Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
ailerons front surface should lightly contact the
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.
The hinge is constructed of a special
material that allows the C/A to wick
or penetrate and distribute
throughout the hinge, securely
bonding it to the wood structure of
the wing panel and aileron.
Note:

WING ASSEMBLY.
8) After both 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
paper towel, remove any excess C/A glue that
may have accumulated on the wing or in the
aileron hinge area.
5) Turn the wing panel over and deflect the
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge, making sure that the C/A penetrates into
both the aileron and wing panel.
Work the aileron up and down several
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.

INSTALLING THE AILERON SERVO.
Install the aileron servo into the servo
mount, with the output shaft towards the leading edge of the wing, using the wood screws
provided with your radio system. Drill 1/16”
pilot holes through the mount before installing
the screws. This will prevent the wood from
splitting.

*If possible, first attempt to balance the model
by changing the position of the receiver battery
and receiver. If you are unable to obt ain good
balance by doing so, then it will be necessary
to add weight to the nose or tail to achieve the
proper balance point.

FLIGHT PREPARATION.
C) Check the elevator first. Pull back
on the elevator stick. The elevator halves
should move up. If it they do not, flip the servo
reversing switch on your transmitter to change
the direction.
A) Check the operation and direction
of the elevator, rudder , ailerons and throttle.
B) Plug in your radio system per the
manufacture’s instructions and turn every thing
on.

Do not use the aerobatic settings for initial test flying or sport flying.
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 LOCATED
65 MM BACK FROM THE LEADING EDGE
OF THE WING AT THE WING ROOT .
3) Turn the airplane upside down. Place
your fingers on the masking tape and carefully
lift the plane .
2) Mount the wing to the fuselage. 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
leading edge of the wing at the wing root. 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 .
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
weight* to the nose. If the nose drops, it is
“nose heavy” 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 carburetor barrel. If it does not, flip the servo reversing switch on your transmitter to change
the direction.
D) Check the rudder. Looking from
behind the airplane, move the rudder stick to
the right. The rudder should move to the right.
If it does not, flip the servo reversing 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 reversing 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 airplane. Do this with the fuel tank empty.
4) Check the control surfaces. All should
move in the correct direction and not bind in
any way .
5) If your radio transmitter is equipped
with dual rate switches double check that they
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) Properly balance the propeller. An out
of balance propeller will cause excessive vibration which could lead to engine and/or airframe failure.
We wish you many safe and enjoyable
flights with your SWIFT40.
