INTRODUCTION.
Thank you for choosing the PC-6 ARTF by SEAGULL MODELS. The PC-6 was designed with
the intermediate/advanced sport flyer in mind. It is a low-wing scale aeroplane which is easy to fly
andquicktoassemble.Theairframeisconventionallybuiltusingbalsa,plywoodandveneertomake
itstrongerthantheaverageARTF,yetthedesignallowstheaeroplanetobekeptlight.Youwillfind
that most of the work has been done for you already. The pushrods are pre-made to the correct
lengths, the motor mount has been fitted and the hinges are pre-installed and pinned for security.
Flying the PC-6 is simply a joy.
This instruction manual is designed to help you build a great flying aeroplane. Please read this
manual thoroughly before starting assembly of your PC-6 . Use the parts listing below to identify all
parts.

1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
2)Removeeach hinge fromthewingpanel
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

Pleasetrialfitallparts.Makesureyouhavethe
correct parts and that they fit and are aligned
properlybeforegluing!Thiswillensureproper
assembly as the PC-6 is made from natural
materialsandminoradjustmentsmay have to
be made. The paint and plastic parts used in
this kit are fuel proof. However, they are not
tolerant of many harsh chemicals including
thefollowing:paintthinner,cyano-acrylateglue
accelerator,cyanoacrylategluede-bonderand
acetone. Do not let these chemicals come in
contact with the colours on the covering and
the plastic parts.

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.
HINGING THE RUDDER.
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.
Note:
Hinge.
5)Turn the wingpanel over anddeflect 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.

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.
2) Usinga modeling knife, cut onelength
ofsiliconfuel line. Connectoneend of theline
tothe weighted fuel pick up andthe otherend
to the nylon pick up tube.(The silicon tube is
not included).
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.

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 difficult to determine which is which.
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.
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.

MOUNTING THE ENGINE.
3) Remove the engine. Using an drill bit,
drill the mounting holes through the engine
mount at the four locations marked.
 1) Place your engine onto the engine
mount. Adjust the engine is centered of the
edges of the engine case.
 2) When you are satisfied with the align-
ment, mark the locations of the engine
mounting.
