Note: Use threadlock on the screws to prevent them from vibrating loose in flight.
Section 6: Receiver Installation Required Parts • Fuselage assembly • Switch • Receiver • Receiver battery • Y-harness or two 3-inch (76mm) extensions • Hook and loop strap (short) Required Tools and Adhesives • Foam rubber • Masking tape Step 3 Secure the receiver as shown using a hook and loop strap. When using a remote receiver, attach the receiver as described in the instructions provided with your radio system, placing it as far away from the main receiver and as high in the fuselage as possible.
Section 7: Canopy and Wing Installation Required Parts • Fuselage assembly • Canopy • Wing panel (right and left) • Wing dowel (2) • Wing tube • Plywood wing bolt plate • 1/4-20 x 2-inch nylon wing bolt (2) • 1 3/16-inch x 3/16-inch (81mm x 4.75mm) aluminum anti-rotation pin Step 2 Use medium sandpaper to scuff the fuselage and canopy where they contact each other. Use rubbing alcohol and a paper towel to remove any debris from the gluing area.
Section 7: Canopy and Wing Installation Step 4 Step 6 Use 30-minute epoxy to glue the wooden dowel into the hole in he leading edge of the wing. Leave 1/2-inch (13mm) of the dowel protruding from the wing as shown. Glue dowels in both wing panels at this time. Install the 1 3/16-inch x 3/16-inch (81mm x 4.75mm) aluminum anti-rotation pin in the hole near the trailing edge of the wing. Use medium CA to glue the pin in position so it will not fall out and get lost.
Section 7: Canopy and Wing Installation Step 8 Step 9 Connect the extensions (or Y-harness) from the receiver to the aileron servos. Attach the wing to the fuselage using two 1/4-20 x 2-inch nylon wing bolts and the plywood wing bolt plate.
Section 8: 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.
Section 9: 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! Step 1 The recommended Center of Gravity (CG) location for the Pulse XT 60 is 3 3/8 inches (86mm) behind the leading edge of the wing against the fuselage. Mark the location of the Center of Gravity on the top of the wing.
Section 10: Pre-Flight Charge both the transmitter and receiver pack for your airplane. Use the recommended charger supplied with your particular radio system, following the instructions provided with the radio. In most cases, the radio should be charged the night before going out flying. Check the radio installation and make sure all the control surfaces are moving correctly (i.e. the correct direction and with the recommended throws).
