ank you for choosing a Direct Airscale model. If you have any problems do not hesitate to consult
our website. Especially the section CLUB DA (Direct Airscale club) for each plane where you will nd
information. You also can consult me directly by phone but try to be a maximum shorter . ank
you. You also can participate in the interaction you’ll nd at general chapter CLUB DA.
Our PILATUS PC 9 is presented in a black and gold livery military parade, held by the Swiss
and Bulgarian armies among others. It is a light aircra that we have equipped a tricycle me-
chanical retracts. A kit for the installation of an electric motor is provided. It is naturally sta-
ble with wings in the format “hang” rectangular double dihedral tailplane and rejected very
rear of the fuselage. Proudly camped on its tricycle landing gear, it is pleasant to look at and fun
to drive. Quite presentable in meetings warbird or interclub. In all modesty is a must 1.80m that
will feel. To respect the genuine our model PC9 is equipped with aps that this type of wing al-
lows to train the reactions induced by the output of the landing aps. e aps are slot eect which
enhances their sweetness and power liing. All characteristics that should take a lot of votes.

To prevent damage to the coating cover
your workbench with a cloth or blanket.
Do not pull on the packaging you may be
too much pressure and break your plane.
Carefully unpack the wings and fuselage us-
ing scissors or a cra knife. Open aware of
hardware apart and sort all parts in order to
understand who goes where. Store in a se-
ries of independent small boxes. When you
work, do not let scews, miscellaneous hard-
ware, accessories and tools below dierent
parts of your aircra. Check constantly. Be-
fore gluing carefully prepare all the parts,
try them and if needed dig slots a bit more.
Work slowly and read many time techni-
cal instructions to be sure to understand all
tricks.Repeat gestures before using glue. If
overows do not use acetone on coatings
and plastics. Oen simply wipe with a paper
towel.
To ensure the mobility of aps we planned
cylindrical hinges. e trick is that these
hinges are installed at 90°mean 45°on each
side. See photos. at way when you leave
the aps deport these hinges and shutters
create a slot eect that brings the li in ad-
dition to limiting the braking eect of tur-
bulence aps and thus repel the stall speed.
All hinges are pre-installed but not glued.
Before removal for sizing carefully locate all
positions with a ballpoint pen not to create a
gap for the collage.Note the middle hinge so
that the same amount is depressed in both
parties. Plant may also serves as a needle
stop which provides the necessary play and
exibility. If you use the cyano coat once all
the hinges with a veil of cyano.
Drill your 45° holes about 2mm before the
edge. Be careful not to cross! Cut hinges
taking into account the thickness of the
wing. Introduce all hinges. e hinges must
be pressed closer, gently so that the oset is
reasonable. To check the alignment of the 3
hinges use simply your eye. If you need to
reduce the oset just push a bit more. Flaps
are manipulated to test the exibility of op-
eration. Monitoring the orientation of the
hinge pins to be perpendicular to the rota-
tional movement.

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.
3) Carefully bend the second nylon tube up
at a 45º angle. is tube is the vent tube.
Carefully use a lighter or heat gun to per-
menently set the angle of the vent tube.

tube.
Important: When the stopper assembly is
installed in the tank, the top of the vent tube
should rest just below the top surface of the
tank. It should not toch the top of the tank.
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.
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.
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.

Blow through one of the lines to ensure
the fuel lines have not become kinked inside
the fuel tank compartment. Air should ow
through easily.
1) Install the pushrod housing through the
predrilled hole in the rewall and into the
servo compartment. e pushrod housing
should protrude 1/4” out past the front of the
rewall. Make a Z-Bend 1/4” from one end
of the plain wire pushrod.
2) Place your engine onto the engine mount.
Adjust the engine is centered of the adges of
the engine case.
4) Remove the engine. Using an drill bit,
drill the mounting holes through the engine
mount at the four location marked.
5) Bolt the engine to the engine mount using
the four machine screws. Double check that
all the screws are tight before proceeding.
6) Attach the Z-Bend in the pushrod wire to
the throttle arm on the carburetor.
3) When you are satised with the alignment,
mark the location of the engine mounting.

COWLING.
1) Slide the berglass cowl over the engine
and line up the back edge of the cowl with
the marks you made on the fuselage then
trim and cut as shown.
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. Use the spinner backplate as a
guide. 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 cut out 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 (4).
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.

INSTALLING THE FUSELAGE SERVOS.
.
Because the size of servos dier, you
may need to adjust the size of the precut
opening in the mount. e notch in the
sides of the mount allow the servo lead to
pass through.
1) Install the rubber grommets and brass
collets onto the throttle servo. Test t the
servo into the aileron servo mount.
2) Secure the servos with the screws pro-
vided with your radio system.
