1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
2)Remove each hinge from thewing 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 sideofthehingeline when
the aileron is mounted to the aileron.
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 wing panel
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 you properly adhere the
hingesin placeper the steps 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
penetrateanddistributethroughout the
hinge, securely bonding it to the wood
structureof the wingpanel and aileron.
To avoid scratching your new aero-
plane we suggest that you cover your work-
benchwith an oldtowel. Keepa couple ofjars

NOTE:
HINGING THE AILERONS.
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,makingsurethat the 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.

HINGING THE ELEVATOR.
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.
HINGING THE RUDDER.
Glue the elevator hinges in place using the
same techniques used to hinge the ailerons.
Glue the rudder hinges in place using the
same techniques used to hinge the ailerons.
Work the aileron up and down several
times to “work in” the hinges and check
for proper movement.

3) Carefully bend the second nylon tube
up at a 45º angle. This tube is the vent tube.
1) Using a modeling knife, carefully cut
off the rear portion of one of the 3 nylon tubes
leaving 1/2” protruding from the rear of the
stopper. This will be the fuel pick up tube.
INSTALLING THE STOPPER ASSEMBLY.
Thread locker glue.
4) Test fit the stopper assembly into the
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.
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.
Carefully use a lighter or heat gun to
permenently set the angle of the vent tube.
See pictures below.Make yourself the
template of your engine on paper.

5) With the stopper assembly in place,
the weighted pick-up should rest away from
therear of the tank 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.

WING ASSEMBLY.
To correctthis,move the battery and receiver
forward orif this is not possible, stick weight
ontothe firewall.When balanced correctly, the
airplane should sit level or slightly nose down
when you lift it up with your fingers.
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
of the plane falls, the plane is tail heavy.
1) It is critical that your airplane be bal-
anced correctly. Improper balance will cause
yourplaneto lose controland crash. The cen-
ter of gravity is locate 10cm back from the
leading edge of the wing, measured at wing
tip.
BALANCING.

FLIGHT PREPARATION.
 A) Check the operation and direction of
the elevator, rudder, ailerons and throttle.
 B) Plug in your radio system per the
manufacturer's instructions and turn every-
thingon.

 C) Check the elevator first. Pull back on
theelevator stick. The elevator halves should
move up. If it they do not, flip the servo re-
versing switch on your transmitter to change
the direction.
 E)Check thethrottle. Moving thethrottle
stick forward should open the carburetor bar-
rel. Ifitdoesnot,fliptheservoreversingswitch
on your transmitter to change the direction.
 D) Check the rudder. Looking from be-
hindthe airplane, move the rudder stick tothe
right. Theruddershould move tothe right. If it
does not, flip the servo reversing switch on
your transmitter to change the direction. 3) Double check the balance of the air-
plane. Do this with the fuel tank empty.
4) Checkthe controlsurfaces. All should
move in the correct direction and not bind in
any way.
6) Check to ensure the control surfaces
are moving the proper amount for both low
and high rate settings.
8) Properly balance thepropeller. 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 NEMESIS.
7) Check the receiver antenna. It should
be fully extended and not coiled up inside the
fuselage.
5) If your radio transmitter is equipped
withdual rate switchesdouble checkthat they
are on the low rate setting for your first few
flights.
2) Check every bolt and every glue joint
in the NEMESIS to ensure that everything is
tight and well bonded.
 F) From behind the airplane, look at the
aileronontheright wing half. Movetheaileron
sticktotheright. Therightaileronshouldmove
upand the otheraileronshould movedown. 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.
