INTRODUCTION.
Thank you for choosing the SEAGULL 2000 ARTF by SEAGULL MODELS. The SEAGULL 2000
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 SEAGULL 2000 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 SEAGULL 2000. 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

ELEVATOR SERVO.
Install the spinner backplate, propeller and
spinner cone.
The propeller should not touch any part
of the spinner cone. If it does, use a sharp
modeling knife and carefully trim away the
spinner cone where the propeller comes in
contact with it.

AILERON SERVO INSTALLATION.
Servos.
String.
Small weight.
1) Using a small weight (Weighted fuel pick-up
works well) and string, feed the string through
the wing as indicated.
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.

3) Set the aileron hatch in place and use a
Phillips screw driver to install it with four wood
screws.

2) A string has been provided in the wing to
pull the aileron lead through to the wing root.
Remove the string from the wing at the servo
location and use the tape to attach it to the
servo extension lead. Pull the lead through the
wing and remove the string.
Attach the string to the servo lead and carefully thread it though the wing.

lead into the receiver. Plug the battery pack
lead into the switch also.
3) Route the antenna in the antenna tube
inside the fuselage and secure it to the bottom
of fuselage using a plastic tape.
2) Wrap the receiver and battery pack in

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
60 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
60 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 60 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 .
*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.
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.

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 SEAGULL 2000 to ensure that everything is tight and well bonded.
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.
We wish you many safe and enjoyable
flights with your SEAGULL 2000.
8) Properly balance the propeller. An out
of balance propeller will cause excessive vibration which could lead to engine and/or airframe failure.
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.
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.
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.
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.
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.
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.
