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
60 MM BACK FROM THE LEADING EDGE
OF THE WINGAT THE WING ROOT.
 3) Turn the airplane upside down. Place
yourfingersonthemaskingtape and carefully
lift the plane .
 2)Mountthewingtothe 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
maywishto experiment byshiftingthebalance
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
alighterandsnappier”feel”. Inanycase,please
start at the location we recommend .
*Ifpossible,firstattempt to balance the model
bychangingthe positionofthereceiverbattery
and receiver. If you are unable to obtain good
balance by doing so, then it will be necessary
toadd weight to the nose or tail toachieve the
proper balance point.
Withthewing attachedtothefuselage,allparts
ofthemodelinstalled( ready to fly),andempty
fuel tanks, hold the model at the
markedbalancepointwiththestabilizerlevel..
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 every-
thing is tight and well bonded.
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.
We wish you many safe and enjoyable
flights with your SEAGULL 2000.
8) Properlybalancethepropeller. Anout
of balance propeller will cause excessive vi-
bration which could lead to engine and/or air-
frame failure.
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.
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.
FLIGHT PREPARATION.
C) Check the elevator first. Pull back
on the elevator stick. The elevator halves
shouldmoveup. Ifittheydonot,fliptheservo
reversingswitchonyourtransmitter to change
the direction.
D) Check the rudder. Looking from
behind the airplane, move the rudder stick to
theright. Theruddershouldmovetotheright.
Ifitdoesnot,fliptheservoreversingswitchon
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’sinstructionsandturneverything
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 re-
versing switch on your transmitter to change
the direction.
