HINGING THE AILERON.
Note : e control surfaces, including the ai-
lerons, 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.
1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
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. is will help ensure an equal amount
of hinge is on either side of the hinge line
when the aileron is mounted to the aileron.
3) Slide the wing panel on the aileron until
there is only a slight gap. e 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.
Hinge.
4) Deect the aileron and completely saturate each hinge with thin C/A glue. e 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.
NOTE : e 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.
C/A glue.
Page 5
Instruction Manual.

5) Turn the wing panel over and deect 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.
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.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
8) Aer both ailerons are securely hinged,
rmly 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.
Work the aileron up and down several times to “work in” the hinges
and check for proper movement.
Note :
HINGING THE ELEVATORS.
Glue the elevator hinges in place using
the same techniques used to hinge the ailerons.

below the top of the tank. It should not touch
the top of the tank.
6) When satised with the alignment of the
stopper assembly tighten the 3 x 20mm machine screw until the rubber stopper expands
and seals the tank opening. Do not overtighten the assembly as this could cause the
tank to split.

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 100 MM BACK
FROM THE LEADING EDGE OF
THE WING AT THE WING ROOT.
3) With the model upright, place your
ngers on the masking tape and carefully
li the plane.
2) Mount the wing to the fuselage. Using
a couple of pieces of masking tape, place
them on the bottom side of the wing
100mm back from the leading edge of the
wing at the wing root.
4) Do not turn plane upside down. Only
low wing models should be turned upsidedown for balancing. Remove this
paragraph, it is not intended for use in
the instructions. it is a note for you.High
Wing models must be balanced upright.
Accurately mark the balance point on
the botttom of the wing on both sides of
the fuselage. e balance point is located
100 mm back from the leading edge of
the wing at the wing root. is is the balance point at which your model should
balance for your rst ights. Later, you
may wish to experiment by shiing the
balance up to 10mm forward or back to
change the ying characteristics. Moving the balance forward may improve the
smoothness and arrow- like tracking, but
it may then require more speed for take
o and make it more dicult to slow
down for landing. Moving the balance a
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
y), and empty fuel tanks, hold the model
at the marked balance point with the stabilizer level.
Li the model. If the tail drops when
you li, 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.
*If possible, rst attempt to balance the
model by changing the position of the receiver battery and receiver. If you are unable to obtain 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.
PREFLIGHT CHECK.
Check the operation and direction
of the elevator, rudder, ailerons and
throttle.
A) Plug in your radio system per the
manufacturer’s instructions and turn
everything on.
B) Check the elevator rst. Pull
back on the elevator stick. e elevator halves should move up. If it they do
not, ip the servo reversing switch on
your transmitter to change the direction.
C) Check the rudder. Looking from
behind the airplane, move the rudder
stick to the right. e rudder should
move to the right. If it does not, ip
the servo reversing switch on your
transmitter to change the direction.
D) Check the throttle. Moving the
throttle stick forward should open the
carburetor barrel. If it does not, ip the
servo reversing switch on your transmitter to change the direction.
E) From behind the airplane, look
at the aileron on the right wing half.
Move the aileron stick to the right.
e right aileron should move up and
the other aileron should move down.
If it does not, ip the servo reversing
switch on your transmitter to change
the direction.
1) Completely charge your transmitter and receiver batteries before
your rst day of ying.
2) Check every bolt and every
glue joint in the
SkyraiderWARBIRD
10cc-15cc 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 rst few ights.
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 ights
with your Skyraider WARBIRD 10CC-15CC.
8) Properly balance the propeller.
An out of balance propeller will cause
excessive vibration which could lead
to engine and/or airframe failure.
