INTRODUCTION
Thank you for choosing the Zero fighter ARTF by SEAGULL MODELS. The Zero fighter 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 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 Zero fighter 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 Zero fighter . 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

NOTE:To avoid scratching your new aero-
plane 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 Zero fighter is made from natu-
ral 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.

! 2. Test fit the dihedral brace into each
wing half. The brace should slide in
easily up to the centreline that you
drew. If not, use 220 grit sandpaper
with a sanding block and sand down
the edges and ends of the brace until
it fits properly.
! 3. Remove the brace when satisfied
with its fit in each wing half. Coat both
sides of one half of the dihedral brace
with 30 minute epoxy. Next, pour
some epoxy into the dihedral box in
one wing panel. Make sure you cover
the top and bottom as well as the
sides of the dihedral brace. Use
enough epoxy to fill any gaps.
! 4. Insert the dihedral brace into the di-
hedral box up to the centreline. With
paper towels wipe off any excess
epoxy that may have squeezed out of
the joint .
Carefully slide the two wing halves together
and firmly press them together, allowing the
excess epoxy to run out. there should should
not be any gap in the wing halves. Use rubbing
alcohol and a paper tower to clean up any
excess epoxy.
Apply masking tape at the wing join to hold the
wing halves together securely .
WING ASSEMBLY
NOTE:We highly recommend using 30
minute epoxy as it is stronger and
provides more working time, allowing
the builder to properly align the parts.
Using fast cure epoxy when joining
the wing halves could result in the
glue drying before the wing halves
are aligned properly which may result
in failure of the wing centre section
during flight.
! 1. Locate the plywood wing dihedral
brace. Using a ruler, locate its central
and draw a vertical line .

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) Remove the stabilizer. Using the lines
you just drew as a guide, carefully remove the
covering from between them using a modeling knife.
! 7) When you are sure that everything is
aligned correctly, mix up a generous amount
of Flash 30 Minute Epoxy. Apply a thin layer
to the top and bottom of the stabilizer mounting area and to the stabilizer mounting platform sides in the fuselage. Slide the stabilizer in place and realign. Double check all of
your measurements once more before the epoxy cures. Hold the stabilizer in place with Tpins or masking tape and remove any excess
epoxy using a paper towel and rubbing alcohol.
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.
! 6) 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.
! 8) After the epoxy has fully cured, re-
move the masking tape or T-pins used to hold
the stabilizer in place. Carefully inspect the

FLIGHT PREPARATION
! 1) Check the operation and direction of
the elevator, rudder, ailerons and throttle.
! A) Plug in your radio system per the
manufacturer's instructions and turn everything on.
! 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.
! 2) Check Control Surface Throw.
! A) The Rudder should move 3/4” left
and 3/4” right from center. If it moves too far,
turn the adjustable control horn out away from
the rudder. Do the opposite if there is not
enough throw.
! B) Both elevator halves should move
5/16” up and 5/16” down from center. If they
move too far, turn the adjustable control horns
out away from the elevator halves. Do the
opposite if there is not enough throw. Both
elevator halves should also travel the same
amount throughout their total movement.
! C) The ailerons should move 3/16” up
and 3/16” down from center. If the ailerons
move too much, turn the adjustable control
horns out away from the wing. Do the opposite if there is not enough throw. It is important that both ailerons move the same amount,
both up and down.
To correct this, move the battery and receiver
forward orif this is not possible, stick weight
onto the firewall or use a brass heavy hub spinner hub, similar to those offered by Harry
Higley. When balanced correctly, the airplane
should sit level or slightly nose down when
you lift it up with your fingers.
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 located 6-8cm back from the
leading edge of the wing, measured at the
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.
! 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.
! D) Once the control throws and movements are set, tubing must be added to the
clevises to ensure they do not release in the
air. Cut a piece of fuel line into five 1/4” long
pieces. Unsnap the clevises and slip one
piece over each clevis. Snap the clevises back
in place and slide the tubing up over them.

CONTROL THROWS
! 1) We highly recommend setting up the
Zero using the control throws listed at right.
We have listed control throws for both Low
Rate (initial test flying/sport flying) and High
Rate (aerobatic flying).
! 2) Turn on the radio system, and with the
trim tabs on the transmitter in neutral, center
the control surfaces by making adjustments
to the clevises or adjustable servo connectors. The servo arms should be centered also.
! 3) When the elevator, rudder and aileron
control surfaces are centered, use a ruler and
check the amount of the control throw in each
surface. The control throws should be mea-
sured at the widest point of each surface!
Low Rate
Caution: Do not use the High Rate (aerobatic settings) for initial test flying or sport
flying.
Ailerons: 1/4” up 1/4” down
Elevator: 1/2” up 1/2” down
Rudder: 3/4” right and left
High Rate
Ailerons: 3/8” up 3/8” down
Elevator: 1” up 1”down
Rudder: 1” right and left
PREFLIGHT CHECK
! 1) Completely charge your transmitter
and receiver batteries before your first day of
flying.
! 2) Check every bolt and every glue joint
in the ZERO FIGHTER 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.
! 8) Properly balance the propeller. An out
of balance propeller will cause excessive vibration which could lead to engine and/or airframe failure.
! 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.
We wish you many safe and enjoyable
flights with your ZERO FIGHTER .
