HARRIER 3D Instruction Manual INTRODUCTION Thank you for choosing the Harrier 3D ARTF by SEAGULL MODELS. The Harrier 3D 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.
HARRIER 3D Instruction Manual 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 Harrier 3D is made from natural materials and minor adjustments may have to be made.
HARRIER 3D 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. ! 1) Carefully remove the aileron from one of the wing panels. Note the position of the hinges. Instruction Manual ! 4)Deflect the aileron and completely saturate each hinge with thin C/A glue.
HARRIER 3D Instruction Manual ! 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.
HARRIER 3D Instruction Manual ! 6) Using C/A remover/debonder and a paper towel, remove any excess C/A glue that may have accumulated on the horizontal stabilizer or in the elevator hinge area. ! 7) Repeat this process with the other horizontal stabilizer panel, securely hinging the elevator in place. ! 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.
HARRIER 3D Instruction Manual Straight line. ! 1) Install the rubber grommets and brass collets onto the aileron servo. Test fit the servo into the aileron servo mount. 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) Locate the nylon control horns,nylon control horn backplates and two machine screws. !!3) Position the aileron horn on the bottom side of aileron.
HARRIER 3D Instruction Manual FUEL TANK PARTS REQUIRED !{1} !{1} !{1} !{1} Molded Nylon Fuel Tank Preassembled Stopper Assembly Metal Weighted Pick-Up 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.
HARRIER 3D 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.
HARRIER 3D Instruction Manual WHEEL AND WHEEL PANTS ! 1) Assemble and mounting the wheel pants as shown in the following pictures. ! 2) Follow diagram below for wheel pant installation: (2) Washer. (2) Washer. (2) Wheel Collar. Axle. Nut. Wheel Collar. Wheel. Axle. Nut. Nut. Nut. Wheel. Landing Gear. Wheel Pant. Landing gear. 8 mm. ! 3) You have to trim each axle using a toll cutting and cut-off wheel. Caution when cutting the axles and wear protective goggles.
HARRIER 3D Instruction Manual INSTALLING THE MAIN LANDING GEAR !1) The blind nuts for securing the landing gear are already mounted inside the fuselage. !2) Using the hardware provided, mount the main landing gear to the fuselage. ! 5) Attach the Z-Bend in the pushrod wire to the throttle arm on the carburetor. You will need to remove the throttle arm from the carburetor to be able to attach the Z-bend. When complete, reattach the throttle arm to the carburetor.
HARRIER 3D Instruction Manual Hard wood block. 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.
HARRIER 3D ELEVATOR - RUDDER SERVO INSTALLATION ! 1) Locate and cut out the covering film from the servo holes in both sides of fuselage. Instruction Manual THROTTLE SERVO INSTALLTION ! 1) Install adjustable servo connector in the servo arm. Adjustable Servo connector. Servo arm. ! 2) Install the rubber grommets and brass collets onto the aileron servo. Test fit the servo into the aileron servo mount.
HARRIER 3D 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. Instruction Manual ! 5) Remove the stabilizer. Using the lines you just drew as a guide, carefully remove the covering from between them using a modeling knife.
HARRIER 3D HINGING THE RUDDER ! 1) Carefully remove the rudder from one of the fuselage panel. Note the position of the hinges. Instruction Manual 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. ! 2) Remove each hinge from the fuselage panel and rudder and place a T-pin in the center of each hinge.
HARRIER 3D Instruction Manual Control Horn. Mounting Screws. Mounting Plate. !3) Using a 1.5mm drill bit and the control horns as a guide, drill the mounting holes through the elevator halves. ! 4) Mount the control horns by inserting the bolts through the control horn bases and elevator halves, then into the mounting backplates. Do not overtighten the nuts or the backplates may crush the wood. ! 5) Position the rudder control horn on the left side of the airplane.
HARRIER 3D Instruction Manual !5) Slide the clasp back into position and carefully glue it into place using Kwik Bond Thin C/A. Hold the clasp in place until the glue completely cures. Rescue the clap with bolt and nut as picture below. !5) Rudder pushrods assembly follow picture below. MOUNTING THE TAIL WHEEL BRACKET !1) Set the tail wheel assembly in place on the plywood plate.

HARRIER 3D Instruction Manual ! 3) Position the battery pack in the fuel tank compartment and the receiver just behind the fuel tank . Use extra foam pieces to hold them in position. When balancing the airplane you may need to move the battery or receiver forward or after to achieve proper balance. Wing bolts( 4 pcs). ! 4) Using a 1/16” drill bit, drill a hole through the side of the fuselage, near the receiver, for the antenna to exit.
HARRIER 3D 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 170 -180mm 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.
HARRIER 3D 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 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.
