COMPANY LTD,. e Skyraider WARBIRD 10cc-15cc was designed with the intermedi-
ate/advanced sport yer in mind. It is a semi scale airplane which is easy to y and quick
to assemble. e airframe is onventionally built using balsa, plywood to make it stronger
than the average ARTF, yet the design allows the aeroplane to be kept light. You will nd
that most of the work has been done for you already. e motor mount has been tted
and the hinges are pre-installed. Flying the Skyraider WARBIRD 10cc-15cc is simply a joy.
is instruction manual is designed to help you build a great ying earoplane. Please read
this manual throughly before starting assembly of your Skyraider WARBIRD 10cc-15cc . User

Please be awere that this aeroplane is not a toy and if assembley or used incorrectly it is
capable of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU
ASSUME ALL RISK & REPONSIBILITY.
If you are inexperienced with basic R/C ight we strongly recommend you contact your R/C
supplier and join your local R/C model Flying Club. R/C Model Flying Clubs oer a variety
of training procedures designed to help the new pilot on his way to successful R/C ight.

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 prop-
erly 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. Re-
move 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) Deect the aileron and completely satu-
rate each hinge with thin C/A glue. e ailer-
ons 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 spe-
cial 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.

5) Turn the wing panel over and deect 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 pa-
per 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) Aer 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 ap-
plying 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 sev-
eral 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 ai-
lerons.
HINGING THE RUDDER.
Glue the rudder hinges in place using
the same techniques used to hinge the ai-

INSTALLING THE STOPPER
ASSEMBLY.
1) Using a modeling knife, carefully cut
o the rear portion of one of the 3 nylon
tubes leaving 1/2” protruding from the
rear of the stopper. is will be the fuel
pick up tube.
2) Using a modeling knife, cut one length
of silicon fuel line. Connect one end of
the line to the weighted fuel pick up and
the other end to the nylon pick up tube.

Fuel fill tube.
3) Carefully bend the second nylon tube up
at a 45º angle. is tube is the vent tube.
4) Test t the stopper assembly into the tank.
It may be necessary to remove some of the
ashing around the tank opening using a
modeling knife. If ashing is present, make
sure none falls into the tank.

5) With the stopper assembly in place, the
weighted pick-up should rest away from the
rear of the tank and move freely inside the
tank. e 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 satised with the alignment of the
stopper assembly tighten the 3 x 20mm ma-
chine screw until the rubber stopper expands
and seals the tank opening. Do not over-
tighten the assembly as this could cause the
tank to split.
FUEL TANK INSTALLATION.
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 dicult to determine which is which.

7) Slide the fuel tank into the fuselage. Guide
the lines from the tank through the hole in
the rewall.
8) Use plywood template to hold in place the
fuel tank with C/A glue to secure the fuel
tank inside the fuselage.

rails to the rewall. Tighten the screws .
Make sure to use threadlock on the screws to
help prevent them from vibrating loose.

3) Use a drill to drill the four holes in the
engine mount rails.

5) Slide the pushrod tube in the rewall
and guide it through the fuel tank mount.
Use medium C/A to glue the tube to the
rewall and the fuel tank mount.
6) Connect the Z-bend in the 450mm
throttle pushrod to the outer hole of the
carburetor arm.
7) Slide the throttle pushrod wire into
the tube. Position the engine between the
mounts. Use four M4x30mm machine
screws to secure the engine to the mount
as shown.

Pushrod wire.
8) Reinstall the servo horn by sliding the
connector over the pushrod wire. Center
the throttle stick and trim and install the
servo horn perpendicular to the servo
center line.
9) Move the throttle stick to the closed po-
sition and move the carburetor to closed.
Use a 2.5mm hex wrench to tighten the
screw that secures the throttle pushrod
wire. Make sure to use threadlock on the
screw so it does not vibrate loose.

1) Slide the berglass cowl over the en-
gine and line up the back edge of the cowl
with the marks you made on the fuselage
then trim and cut as shown.
Because of the size of the cowl, it may be nec-
essary to use a needle valve extension for the
high speed needle valve. Make this out of suf-
cient length 1.5mm wire and install it into
the end of the needle valve. Secure the wire in
place by tightening the set screw in the side of
the needle valve.
2) While keeping the back edge of the cowl
ush with the marks, align the front of the
cowl with the cranksha of the engine. e
front of the cowl should be positioned so the
cranksha is in nearly the middle of the cowl
opening. Hold the cowl rmly in place using
pieces of masking tape.
3) Install the muer and muer extension
onto the engine and make the cutout in the
cowl for muer clearance. Connect the fuel
and pressure lines to the carburetor, muer
and fuel ller valve. Secure the cowl to fuse-
lage using the M3x10mm screws.
