SEAGULL FUNFLY 3D.
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.

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.
Hinge.
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.
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.
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 wing panel and aileron.
Note: Work the aileron up and down several
times to “work in” the hinges and

3) Carefully bend the second nylon tube
up at a 45º angle. This tube is the vent tube.
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.

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.
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.
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.
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.

to only cut through the covering itself. Cutting into the balsa structure may weaken
it.
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.
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.

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 .

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

BALANCING.
ATTACHMENT WING-FUSELAGE.
Attach the aluminium tube into fuselage.
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 LOCATED
110 MM BACK FROM THE LEADING EDGE
OF THE WING AT THE WING ROOT.
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.
Wing tube.
Insert two wing panels as pictures below.
3) Turn the airplane upside down. Place
your fingers on the masking tape and carefully
lift the plane .
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 .
23
Instruction Manual.
SEAGULL FUNFLY 3D.
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.
*If possible, first attempt to balance the model
by changing the position of the receiver battery
and receiver. If you are unable to obtain good
balance by doing so, then it will be necessary
to add weight to the nose or tail to achieve the
proper balance point.
110mm.
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.
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.
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.
