ZERO FIGHTER. Instruction Manual 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.
ZERO FIGHTER. 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 Zero fighter is made from natural materials and minor adjustments may have to be made.

INSTRUCTION MANUAL 8) Cut the wire 1/2” past the mark and make an “ L ” bend . !5) Mount the control horns by inserting the screws through the control horn bases and aileron halves, then into the mounting backplates. Do Not overtighten the screws or the backplates may crush the wood. 6) Thread one nylon adjustable control horn onto each aileron torque rod.
ZERO FIGHTER. Instruction Manual 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 .
ZERO FIGHTER. INSTRUCTION MANUAL INSTALLING THE PILOT. ! 1.If you plan on using a pilot in your Zero fighter .46, now is the time to mount it to the cockpit floor area of the hatch. ! 2. After cutting out the canopy, trial fit it to fuselage. Trim as necessary to make a proper fit. ! 3.After confirming the fit of the canopy to the fuselage, attach it to the fuselage using canopy glue. Masking tape can be used to hold the canopy in place while the glue dries. Allow the canopy glue to dry. Glue attached.

If flashing is present, make sure none falls into the tank. Top of Tank Vent tube Fuel Pickup Tube ! 3) Carefully bend the second nylon tube up at a 45º angle. This tube is the vent tube. Use a lighter or heat gun to heat the vent tube. The vent tube must be heated so it will be man at a 45o angle.

ZERO FIGHTER. Instruction Manual INSTALLING THE SERVOS ! 1. Install the rubber grommets and brass collets onto the elevator, rudder and throttle servos. Test fit the servos into the preinstalled servo tray.Because the size of servos differ, you may need to adjust the size of the precut openings in the tray. ! 2. Position the servos into the servo tray with the output shafts orientated as shown below. Drill 1mm pilot holes through the tray for each of the mounting screws.

INSTRUCTION MANUAL Remove covering ! 2) Using a modeling knife, carefully remove the covering from over the vertical stabilizer mounting slot in the top of the fuselage. ! 3) Slide the stabilizer into place in the precut slot in the rear of the fuselage. The stabilizer should be pushed firmly against the front of the slot.

Instruction Manual Remove covering ALIGNING THE VERTICAL STABILIZER ! 1) Using a modeling knife, remove the covering from over the precut hinge slot cut into the lower rear portion of the fuselage. This slot accepts the lower rudder hinge. ! 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.

Do Not overtighten the screws or the backplates may crush the wood.
ZERO FIGHTER. 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.
ZERO FIGHTER. Instruction Manual 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.
