EDGE 540. Instruction Manual. INTRODUCTION. Thank you for choosing the EDGE 540 ARTF by SEAGULL MODELS. The EDGE 540 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.
EDGE 540. 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 EDGE 540 is made from natural materials and minor adjustments may have to be made.
EDGE 540. Instruction Manual. 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. 4)Deflect the aileron and completely saturate each hinge with thin C/A glue.
EDGE 540. Instruction Manual. 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. HINGING THE ELEVATORS.

Insert two wing panels as pictures below: 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 locate100-110mm 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.
EDGE 540. 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.
