INTRODUCTION.
Thank you for choosing the NEMESIS ARTF by SEAGULL MODELS. The NEMESIS was
designedwiththeintermediate/advanced sportflyer inmind. Itis a scale airplane whichis easyto
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
thatmostoftheworkhasbeendoneforyoualready. Themotormounthasbeenfittedandthehinges
are pre-installed . Flying the NEMESIS is simply a joy.
This instruction manual is designed to help you build a great flying aeroplane. Please read this
manualthoroughlybeforestartingassemblyofyourNEMESIS.Usethepartslistingbelowtoidentify
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.

couple of jars or bowls handy to hold
the small parts after you open the
bags.
Pleasetrialfitallparts.Makesureyou
have the correct parts and that they
fit and are aligned properly before
gluing! This will ensure proper as-
sembly as the NEMESIS is made
from natural materials and minor ad-
justments may have to be made.
The paint and plastic parts used in
this kit are fuel proof. However, they

1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
2)Removeeach hinge fromthewing 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
ofhingeison either sideofthehinge line when
the aileron is mounted to the aileron.
HINGING THE AILERONS.
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
shouldbe maintained betweenthe wingpanel
andaileron.
The control surfaces, including the
ailerons, elevators, and rudder, are
prehinged with hinges installed, but the
hinges are not glued in place. It is
imperativethat youproperly adhere the
hingesin placeper thesteps that follow
using a high-quality thin C/A glue.
Note:
4)Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
aileronsfrontsurfaceshould lightly contactthe
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.
Note: The hinge is constructed of a special
material that allows the C/A to wick or
penetrateanddistribute throughout the
hinge, securely bonding it to the wood
structureof the wingpanel andaileron.

8)Afterbothailerons are securelyhinged,
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.
5)Turn the wing panel over anddeflect the
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge,makingsurethatthe C/A penetrates into
both the aileron and wing panel.
6) Using C/A remover/debonder and a
papertowel, remove anyexcess C/A gluethat
may have accumulated on the wing or in the
aileronhinge area.

Carefully use a lighter or heat gun to

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.
Venttube. Fuel pick up tube.
Fuel fill tube.
5) With the stopper assembly in place,
the weighted pick-up should rest away from
therear of thetank and move freely insidethe
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.
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.
Important: When the stopper assembly is in-
stalled in the tank, the top of the vent tube
should rest just below the top surface of the
tank. It should not touch the top of the tank.

Insert two wing panels as pictures below.
1) It is critical that your airplane be bal-
anced correctly. Improper balance will cause
yourplaneto losecontroland crash. The cen-
ter of gravity is locate 180mm back from the
leading edge of the wing, measured at wing
tip.
BALANCING.
2) If the nose of the plane falls, the plane
is nose heavy. To correct this first move the
battery pack further back in the fuselage. If
this is not possible or does not correct it, stick
small amounts of lead weight on the fuselage
sides under the horizontal stabilizer. If the tail
oftheplanefalls,the plane is tailheavy.To cor-
rect this, move the battery and receiver for-
ward orif this is not possible, stick weight onto
the firewall.When balanced correctly, the air-
plane should sit level or slightly nose down
when you lift it up with your fingers.

4) Checkthe controlsurfaces. All should
move in the correct direction and not bind in
any way.
5) If your radio transmitter is equipped
withdual rate switchesdouble checkthat 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.
8) Properlybalance the propeller. Anout
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 EXTRA 300S.
7) Check the receiver antenna. It should
be fully extended and not coiled up inside the
fuselage.

PREFLIGHT CHECK.
1) Completely charge your transmitter and
receiver batteries before your first day of fly-
ing.
2) Check every bolt and every glue joint in
theNEMESIS toensurethat everything istight
and well bonded.
3) Double check the balance of the air-
plane. Do this with the fuel tank empty.
 E) Checkthe throttle. Movingthe throttle
stick forward should open the carburetor bar-
rel. Ifitdoesnot,fliptheservoreversingswitch
