Instruction Manual
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
and quick to assemble. The airframe is conventionally built using balsa, plywood and veneer to make
it stronger than the average ARTF , yet the design allows the aeroplane to be kept light. You will find
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.
WARNING.
Please be aware that this aeroplane is not a toy and if assembled or used incorrectly it is capable
of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU ASSUME ALL
RISK & RESPONSIBILITY.
If you are inexperienced with basic R/C flight we strongly recommend you contact your R/C
supplier and join your local R/C Model Flying Club. R/C Model Flying Clubs offer a variety of training
procedures designed to help the new pilot on his way to successful R/C flight. They will also be able
to advise on any insurance and safety regulations that may apply.

NOTE: To avoid scratching your new aeroplane we suggest that you cover your workbench with an old towel. Keep a couple of jars
or bowls handy to hold the small parts after you
open the bags.
Please trial fit all parts. Make sure you have the
correct parts and that they fit and are aligned
properly before gluing! This will ensure proper
assembly as the PC-6 is made from natural
materials and minor adjustments may 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
the following: paint thinner, cyano-acrylate glue
accelerator, cyanoacrylate glue de-bonder and
acetone. Do not let these chemicals come in
contact with the colours on the covering and
the plastic parts.
T- pin.
Hinge.
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
should be maintained between the wing panel
and aileron.
T- pin.
Hinge.
HINGING THE AILERONS.
Note: The control surfaces, including the
ailerons, 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.
4)Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
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.
The hinge is constructed of a special
Note: 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.
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. This will help ensure an equal amount
of hinge is on either side of the hinge line when
the aileron is mounted to the aileron.
C/A glue.

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, making sure that the C/A penetrates into
both the aileron and wing panel.
Instruction Manual
HINGING THE RUDDER.
Glue the rudder hinges in place using the
same techniques used to hinge the ailerons.
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) 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.
Apply epoxy glue.
Note: Work the aileron up and down several
times to “work in” the hinges and check
for proper movement.

INSTALLING THE STOPPER ASSEMBLY.
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.
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.(The silicon tube is
not included).
3) Carefully bend the second nylon tube
up at a 45º angle. This tube is the vent tube.

Carefully use a lighter or heat gun to
permenently set the angle of the vent 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 touch the top of the tank.
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.

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. 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 expands and seals the tank opening. Do not
overtighten the assembly as this could cause
the tank to split.

FUEL TANK INSTALLATION.
Blow through one of the lines to ensure
the fuel lines have not become kinked inside the fuel tank compartment. Air should
flow through easily.
MOUNTING THE ENGINE.
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.
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 alignment, mark the locations of the engine
mounting.
3) Remove the engine. Using an drill bit,
drill the mounting holes through the engine
mount at the four locations marked.

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 locate 8cm back from the leading edge of the wing, measured at wing tip.
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.
To correct this, move the battery and receiver
forward orif this is not possible, stick weight
onto the firewall.When balanced correctly, the
airplane should sit level or slightly nose down
when you lift it up with your fingers.
C) Check the elevator first. Pull back on
the elevator stick. The elevator halves should
move up. If it they do not, flip the servo reversing switch on your transmitter to change
the direction.
D) Check the rudder. Looking from behind the airplane, move the rudder stick to the
right. The rudder should move to the right. If it
does not, flip the servo reversing switch on
your transmitter to change the direction.
E) Check the throttle. Moving the throttle
stick forward should open the carburetor barrel. If it does not, flip the servo reversing switch
on your transmitter to change the direction.
F) From behind the airplane, look at the
aileron on the right wing half. Move the aileron
stick to the right. The right aileron should move
up and the other aileron should move down. If
it does not, flip the servo reversing switch on
your transmitter to change the direction.
PREFLIGHT
CHECK.
FLIGHT
PREPARATION.
8cm.
1) Completely charge your transmitter
and receiver batteries before your first day of
flying.
2) Check every bolt and every glue joint
in the PC-6 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.
CONTROL THROWS.
Ailerons: 10 Low rate 12 High rate
Elevator: 8 Low rate
10 High rate
Rudder: 15 Low rate 20 High rate
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 everything on.
5) If your radio transmitter is equipped
with dual rate switches double check that they
are on the low rate setting for your first few
flights.
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.
8) Properly balance the propeller. An out
of balance propeller will cause excessive vibration which could lead to engine and/or airframe failure.
We wish you many safe and enjoyable
flights with your PC-6 .
