INTRODUCTION.
Thank you for choosing the Harrier 3D .46 ARTF by SEAGULL MODELS. The Harrier 3D .46 was designed with the intermediate/advanced sport flyer in mind. It is a 3D 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 motor mount has been fitted and the hinges are pre-installed . Flying the Harrier 3D .46 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 Harrier 3D .46 . Use the parts listing below to identify all parts.

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 Harrier 3D .46 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.

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.
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.
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 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.
HINGING THE AILERONS.
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.
3) Slide the aileron on the wing panel 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.
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.
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.

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:
Work the aileron up and down several times to “work in” the hinges and check for proper movement.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
1) Carefully remove the elevator from one
of the horizontal stabilizer panels. Note the position of the hinges.
2) Remove each hinge from the horizontal
stabilizer 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 horizontal stabilizer panel.
3) Slide the elevator on the horizontal
stabilizer panel until there is only a slight gap. The hinge is now centered on the horizontal stabilizer panel and elevator. Remove the T­pins and snug the elevator against the horizontal stabilizer panel. A gap of 1/64” or less should be maintained between the horizontal stabilizer panel and elevator.
4)Deflect the elevator and completely
saturate each hinge with thin C/A glue. The elevators front surface should lightly contact the horizontal stabilizer 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 horizontal stabilizer 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 horizontal stabilizer panel and elevator.
5) Turn the horizontal stabilizer panel over
and deflect the elevator in the opposite direction from the opposite side. Apply thin CA glue to each hinge, making sure that the C/A penetrates into both the elevator and horizontal stabilizer panel.

8) After both horizontal stabilizer are
securely hinged, firmly grasp the horizontal stabilizer panel and elevator to make sure the hinges are securely glued and cannot be pulled out. Do this by carefully applying medium pressure, trying to separate the elevator from the horizontal stabilizer panel. Use caution not to crush the horizontal stabilizer structure.
7) Repeat this process with the other
horizontal stabilizer panel, securely hinging the elevator in place.
Using a small weight (Weighted fuel pick-up works well) and thread, feed the string through the wing as indicated.
INSTALLING THE AILERON SERVOS.
Attach a 12 inch servo lead to the aileron servo. Attach the string to the servo lead and carefully thread it though the wing. Once you have thread the lead throught the wing, remove the string so it can use for the other servo lead. Tape the servo lead to the wing to prevent it from falling back into the wing.

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. .
PARTS REQUIRED
FUEL TANK.
{1} Molded Nylon Fuel Tank{1} Preassembled Stopper Assembly{1} Metal Weighted Pick-Up{1} Silicon tube
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 pickup and the other end to the nylon pickup tube.
3) Carefully bend the second nylon tube up at a 45º angle. This tube is the vent tube.
5) With the stopper assembly in place, the weighted pickup 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 3mm 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.
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.
Attach the silicone fuel and pressure pipes to the tank. The lower pipe is the ‘feed’ and the upper two the ‘pressure and fill’. The fill pipe is the next pipe.
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

1) Locate and cut out the covering film
from the servo holes in both sides of fuselage.
2) Install the rubber grommets and brass collets onto the aileron servo. Test fit the servo into the aileron servo mount.
Because of the size of the cowl, it may
be necessary to use a needle valve ex­tension for the high speed needle valve. Make this out of sufficient length 1.5mm wire and install it into the end of the needle valve. Se­cure the wire in place by tightening the set screw in the side of the needle valve.
3) Install the muffler and muffler extension onto the engine and make the cutout in the cowl for muffler clearance. Connect the fuel and pressure lines to the carburetor, muffler and fuel filler valve. Secure the cowl to fuse­lage using the 3mmx12mm screws (4).
Install the spinner backplate, propeller and spinner cone. The spinner cone is held in place using two 3mm x 12mm wood screws.
The propeller should not touch any part
of the spinner cone. If it does, use a sharp modeling knife and carefully trim away the spinner cone where the propeller comes in contact with it.

2)Using a modeling knife, carefully remove the covering at mounting slot of horizontal sta­bilizer ( both side of fuselage).
3) Slide the stabilizer into place in the pre- cut slot in the rear of the fuselage. The stabi­lizer should be pushed firmly against the front of the slot.
4) 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.
HORIZONTAL STABILIZER.
1) Using a ruler and a pen, locate the centerline of the horizontal stabilizer, at the trail­ing edge, and place a mark. Use a triangle and extend this mark, from back to front, across the top of the stabilizer. Also extend this mark down the back of the trailing edge of the stabilizer.
Because the size of servos differ, you may need to adjust the size of the precut opening in the mount. The notch in the sides of the mount allow the servo lead to pass through.
2) Install the rubber grommets and brass collets onto the throttle servo. Test fit the servo into the aileron servo mount.
3) Secure the servos with the screws pro- vided with your radio system.
4) Install the pushrod throttle.
6) Using a modeling knife, carefully re-
move 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.
7) When you are sure that everything is aligned correctly, mix up a generous amount of 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 T-pins 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.
5) Remove the stabilizer. Using the lines you just drew as a guide, carefully remove the covering from between them using a model­ing knife.

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

1) Set the tail wheel assembly in place on the plywood plate. The pivot point of the tail wheel wire should be even with the rudder hinge line and the tail wheel bracket should be centered on the plywood plate. 2 Using a pen, mark the locations of the two mounting screws. Remove the tail wheel bracket and drill 1mm pilot holes at the loca­tions marked.
MOUNTING THE TAIL WHEEL BRACKET.
3) Secure the tail wheel bracket in place us­ing two 3mm x 15mm wood screws. Be care­ful not to overtighten the screws.
1) Align the tail wheel wire so that the wire is parallel with the bottom of the rudder. The control clasp has a predrilled hole through the top of it. Slide this hole onto the tail wheel wire while sliding the clasp over the bottom of the rudder.
MOUNTING THE CONTROL CLASP.
2) Using a ruler and a pen place a mark onto the bottom of the rudder, in front of the rear edge of the tail wheel wire. The back edge of the clasp should line up with this mark. You may find it necessary to bend the tail wheel wire down slightly so it lines up with the clasp without binding.
3) While holding the clasp firmly in place, use a pen and outline the clasp onto the rud­der.
4) Remove the clasp, and using a modeling knife, remove the covering from inside the lines you drew. Use 220 grit sandpaper and care­fully roughen the inside surface of the nylon clasp.

CONTROL THROWS.
1) We highly recommend setting up the
Harrier 3D .46 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.
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.
1) It is critical that your airplane be bal- anced correctly. Improper balance will cause your plane to lose control and crash. The cen­ter of gravity is located
140-150mm back from the leading edge of the wing, measured at the fuselage.
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
BALANCING.
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
measured at the widest point of each sur­face!
4) By moving the position of the adjust- able control horn out from the control surface, you will decrease the amount of throw of that control surface. Moving the adjustable con­trol horn toward the control surface will in­crease the amount of throw.

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.
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 Harrier 3D .46 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.
6) Check to ensure the control surfaces are moving the proper amount for both low and high rate settings.
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 Harrier 3D .46.
7) Check the receiver antenna. It should be fully extended and not coiled up inside the fuselage.
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.
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.
