Step 3 Slide the hinges into the aileron.
Section 1: Aileron Installation Step 5 Step 7 Position the aileron so it can move freely and not . bind at the wing tip or wing root. Deflect the aileron without changing the hinge gap, and apply thin CA to . each of the four hinges. Apply CA to both the top and bottom of the hinges. Flex the aileron up and down a number of times to break in the hinges. Note: Do not use CA accelerator on the hinges; the CA must be allowed to soak into the hinge.
Section 1: Aileron Installation Step 9 Step 11 Slide one of the longer pushrod wires into the wing. Attach the servo extension to the “Z” bend of the . pushrod wire. Place the servo into the opening with the servo output towards the trailing edge of the wing. Use a felt-tipped pen to mark the locations for the four servo mounting screws. Step 12 Remove the servo and drill the locations for the servo mounting screws using a 1/16" (1.5mm) drill bit. .
Section 1: Aileron Installation Step 13 Secure the servo using the screws provided with . the servo. Note: You may want to use tape at the wing tip and wing root to hold the aileron in position for the next few steps. Step 16 Plug the aileron servo into the radio system. With the radio on, center the aileron stick and trim. Position the aileron servo arm parallel to the hinge line. Thread the clevis so the pin in the clevis is aligned with the trailing edge of the wing.
Section 1: Aileron Installation Step 18 Step 19 Use a 5/64" (2mm) drill bit to drill the locations for the control horn screws. Place a few drops of thin CA into each hole to harden the underlying wood. This will help in preventing the wood from crushing when tightening the control horn screws.

Section 8: Final Assembly Step 6 Step 7 Slide the remaining wing panel onto the wing tube aligning the dowel into the panel. Slide the 1/4-20 x 1 1/2" wing bolts through the wing bolt plate. Position the wing dowels into the holes in the fuselage. Slide the bolts through the wing and tighten them to secure the wing to the fuselage.
Control Throws The amount of control throw should be adjusted as closely as possible using mechanical means, rather than making large changes electronically at the radio. By moving the position of the clevis at the control horn toward the outermost hole, you will decrease the amount of control throw of the control surface. Moving it toward the control surface will increase the amount of throw.
Recommended Center of Gravity (CG) An important part of preparing the aircraft for flight is properly balancing the model. This is especially important when various engines are mounted. Caution: Do not inadvertently skip this step! The recommended Center of Gravity (CG) location for . the Pulse XT is 2 3/4" (70mm) behind the leading edge . of the wing against the fuselage. Make sure the aircraft . is inverted when measuring the CG. If necessary, move .
Adjusting the Engine (Glow) Step 1 Step 3 Completely read the instructions included with your engine and follow the recommended break in procedure. Before you fly, be sure that your engine idles reliably, transitions and runs at all throttle settings. Only when this is achieved should any plane be considered ready for flight. Step 2 At the field, adjust the engine to a slightly rich setting at full throttle and adjust the idle and low-speed needle so that a consistent idle is achieved.
Glossary of Terms • Ailerons: Each side of this airplane has a hinged control surface (aileron), located on the trailing edge of the wing. Move the aileron stick on the transmitter left, the left aileron moves up and the right aileron moves down. Moving the left aileron up causes more drag and less lift, causing the left wing to drop down. When the right aileron moves down, more lift is created, causing the right wing to rise. This interaction causes the airplane to turn or roll to the left.
2006 Official AMA National Model Aircraft Safety Code GENERAL 1) I will not fly my model aircraft in sanctioned events, air shows or model flying demonstrations until it has been proven to be airworthy by having been previously, successfully flight tested. 2) I will not fly my model higher than approximately 400 feet within 3 miles of an airport without notifying the airport operator. I will give right-of-way and avoid flying in the proximity of full-scale aircraft.
2006 Official AMA National Model Aircraft Safety Code 5) Flying sites separated by three miles or more are considered safe from site-to site interference, even when both sites use the same frequencies. Any circumstances under three miles separation require a frequency management arrangement, which may be either an allocation of specific frequencies for each site or testing to determine that freedom from interference exists.
