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. 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. 1) Carefully remove the aileron from one of the wing panels. Note the position of the hinges. C/A glue. 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 wing panel until the T-pin is snug against the wing panel. This will help ensure an equal amount of hinge is on either side of the hinge line when the aileron is mounted to the 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. T-pin. Hinge. 3) Slide the wing panel on the aileron 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. T-pin. 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. 4 C/A glue. 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. 7) Repeat this process with the other wing panel, securely hinging the aileron in place. Note: Work the aileron up and down several times to “work in” the hinges and check for proper movement. www.seagullmodels.com HINGING THE RUDDER.

Improper balance will cause your plane to lose control and crash. The center of gravity is locate 7cm back from the leading edge of the wing, measured at 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. To correct this, move the battery and receiver forward orif this is not possible, stick weight onto the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers. CONTROL THROWS. Wing bolt. 1) We highly recommend setting up the X-RAY 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. Wing bolt. 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! INITIAL FLYING/SPORT FLYING Ailerons : Elevator : Rudder : 3/16” up 3/8” up 3/4 right 3/16” down 3/8” down 3/4 left AEROBATIC FLYING Ailerons : Elevator : Rudder : 3/8” up 3/8” down 7/8” up 7/8” down 1-1/4” right 1-1/4” left Do not use the aerobatic settings for initial test flying or sport flying. 13 X-RAY. Instruction Manual. 4) By moving the position of the adjustable 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. 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. 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. 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 X-RAY to ensure that everything is tight and well bonded. 3) Double check the balance of the airplane. Do this with the fuel tank empty. 14 4) Check the control surfaces. All should move in the correct direction and not bind in any way. 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. 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 X-RAY.
