INTRODUCTION.
Thank you for choosing the SEAGULL FUNFLY 3D ARTF by SEAGULL MODELS COMPANY LTD.
The SEAGULL FUNFLY 3D was designed with the intermediate/advanced sport flyer in mind. It
is a semi scale airplane which is easy to fly and quick to assemble. The airframe is conventionally
built using balsa, plywood 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 motor
mount has been fitted and the hinges are pre-installed. Flying the SEAGULL FUNFLY 3D 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 SEAGULL FUNFLY 3D . Use the parts listing
below to identify all parts.
WARNING.
Please be aware that this aeroplane is not a toy and if it is assembled or used incorrectly it
will cause 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.

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.
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 aileron
until the T -pin is snug against the aileron. This
will help ensure an equal amount of hinge is
on either side of the hinge line when the aileron
is mounted to the wing panel.

INSTALL THE AILERONS CONTROL
HORN.
1) Locate the hardware necessary to install
the control horns for the ailerons.
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.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
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.
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.
Work the aileron up and down several
times to “work in” the hinges and
Note:
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
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.
Note:

6) With the stabilizer held firmly in place,
use a pen and draw lines onto the stabilizer
where it and the fuselage sides meet. Do this
on both the right and left sides and top and
bottom of the stabilizer.
5) When you are satisfied with the alignment, hold the stabilizer in place with T- pins
or masking tape, but do not glue at this time.

7) Remove the stabilizer . Using the lines
you just drew as a guide, carefully remove the
covering from between them using a modeling knife.
Remove the covering.
8) Using a modeling knife, carefully remove the covering that overlaps the stabilizer
mounting platform sides in the fuselage. Remove the covering from both the top and the
bottom of the platform sides.
When cutting through the covering to
remove it, cut with only enough pressure
to only cut through the covering itself. Cutting into the balsa structure may weaken
it.
4) Install the stabilizer onto the fuselage.
Align the centerline drawn on the top and the
rear of the stabilizer with the centre of the fuselage. When that is aligned, hold the stabilizer in that position using T-pins or masking
tape. Align the horizontal stabilizer with the
wing. When viewed from the rear, the horizontal stabilizer should be level with the wing.
If it is not level, use sandpaper and sand down
the high side of the stabilizer mounting platform until the proper alignment is achieved.
The tips of the stabilizer should also be equal
distance from the tips of the wing.
10) After the epoxy has fully cured, remove the masking tape or T -pins used to hold
the stabilizer in place. Carefully inspect the
glue joints. Use more epoxy to fill in any gaps
that may exist that were not filled previously
and clean up the excess using a paper towel
and rubbing alcohol.

9) When you are sure that everything is
aligned correctly, mix up a generous amount
of 30 Minute Epoxy. Apply a thin layer to the
bottom of the stabilizer mounting area and to
the stabilizer mounting platform sides in the
fuselage. Putting the stabilizer in place and
realign. Double check all of your measurements once more before the epoxy cures.
Hold the stabilizer in place with T -pins or masking tape and remove any excess epoxy using
a paper towel and rubbing alcohol.

HINGING THE ELEVATOR.
Epoxy.
1) Carefully remove the elevator from one
of the fuselage panel. Note the position of the
hinges.
2) Remove each hinge from the fuselage
panel and elevator and place a T-pin in the
center of each hinge. Slide each hinge into the
elevator until the T-pin is snug against the
elevator. This will help ensure an equal amount
of hinge is on either side of the hinge line when
the elevator is mounted to the fuselage .
3) Slide the elevator on the fuselage panel
until there is only a slight gap. The hinge is
now centered on the fuselage panel and
elevator. Remove the T-pins and snug the
elevator against the fuselage panel. A gap of
1/64” or less should be maintained between
the fuselage panel and elevator.
4)Deflect the elevator and completely
saturate each hinge with thin C/A glue. The
elevator front surface should lightly contact
the fuselage 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 elevator to the fuselage panel hinge
line.
Note: The 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 fuselage
panel and rudder.

5) Slide the vertical stabilizer back in
place. Using a triangle, check to ensure that
the vertical stabilizer is aligned 90º to the horizontal stabilizer.
When cutting through the covering to re-
move it, cut with only enough pressure to
only cut through the covering itself. Cutting
into the balsa structure may weaken it.
2) Slide the vertical stabilizer into the slot
in the top of the fuselage. The rear edge of
the stabilizer should be flush with the rear edge
of the fuselage and the lower rudder hinge
should engage the precut hinge slot in the
lower fuselage. The bottom edge of the stabilizer should also be firmly pushed against the
top of the horizontal stabilizer .
3) While holding the vertical stabilizer
firmly in place, use a pen and draw a line on
each side of the vertical stabilizer where it
meets the top of the fuselage.

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 GRA VITY IS LOCATED
110 MM BACK FROM THE LEADING EDGE
OF THE WING AT THE WING ROOT.
3) Turn the airplane upside down. Place
your fingers on the masking tape and carefully
lift the plane .
2) Mount the wing to the fuselage. Using a
couple of pieces of masking tape, place them
on the top side of the wing
110 mm back from
the leading edge of the wing at the wing root.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located
110 mm back from
the leading edge of the wing at the wing root.
This is the balance point at which your model
should balance for your first flights. Later , you
may wish to experiment by shifting the balance
up to 10mm forward or back to change the
flying characteristics. Moving the balance
forward may improve the smoothness and
arrow- like tracking, but it may then require
more speed for take off and make it more
difficult to slow down for landing. Moving the
balance aft makes the model more agile with
a lighter and snappier ”feel”. In any case,please
start at the location we recommend .
Insert two wing panels as pictures below.
3 x 10mm.
ATTACHMENT WING-FUSELAGE.

1) Plug the five servo leads and the switch
lead into the receiver. Plug the battery pack
lead into the switch also.
3) Route the antenna in the antenna tube
inside the fuselage and secure it to the bottom of fuselage using a plastic tape.
2) Wrap the receiver and battery pack in
the protective foam rubber to protect them
from vibration.

*If possible, first attempt to balance the model
by changing the position of the receiver battery
and receiver. If you are unable to obt ain good
balance by doing so, then it will be necessary
to add weight to the nose or tail to achieve the
proper balance point.
With the wing attached to the fuselage, all
parts of the model installed ( ready to fly), and
empty fuel tanks, hold the model at the marked
balance point with the stabilizer level.
Lift the model. If the tail drops when you lift,
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.

past of the elevator,rudder ,and aileron unless noted
otherwise.
Use the following throws for 3D aerobatics:
Aileron: 2 1/2-inch(35 )up 2 1/2-inch(35 )down.
Elevator: 2 3/4-inch(35 )up 2 3/4-inch(35 )down.
Rudder: 2 1/2-inch(28 )right 2 1/2-inch(28 )left.
D) 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.
E) 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.
C) 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.
A) Plug in your radio system per the
manufacturer's instructions and turn everything on.
Check the operation and direction of the
elevator, rudder, ailerons and throttle.
FLIGHT PREPARATION.
7) Check the receiver antenna. It should
be fully extended and not coiled up inside the
fuselage.
3) Double check the balance of the airplane. Do this with the fuel tank empty.
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.
2) Check every bolt and every glue joint
in the SEAGULL FUNFL Y 3D to ensure that
everything is tight and well bonded.
6) Check to ensure the control surfaces
are moving the proper amount for both low
and high rate settings.
1) Completely charge your transmitter
and receiver batteries before your first day of
flying.
8) Properly balance the propeller. An out
of balance propeller will cause excessive vibration which could lead to engine and/or airframe failure.
PREFLIGHT CHECK.
B) 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.
4) Check the control surfaces. All should
move in the correct direction and not bind in
any way .
We wish you many safe and enjoyable
flights with your SEAGULL FUNFLY 3D.
