- Page 3 Page 3 of 15 Cut 4, three inch long strips of fiberglass drywall tape. Stick the tape on the inside of the fuse as shown and spread Foam-tac over the tape with a scrap of EPP foam. After glue has dried, cut off and tape that is hanging over the edge.
- Page 4 Page 4 of 15 Cut out the scrap foam pieces to open the tail and tab holes, also make a cut to separate the top and bottom tabs in the tail. Use a liberal amount of Foam-tac to glue the plywood motor mount to foam bulkhead as shown.
- Page 5 Page 5 of 15 Glue the bottom and the other half of the fuse in place using the slots and tabs provided, lay weights on it until the glue dries. Now glue the second 25.250” spar into the corner of the fuse as shown. A third small support bulkhead is now glued in the fuse using the tab and slot provided.
- Page 6 Page 6 of 15 Glue the 4 flat carbon spars to the trailing edge of the ailerons. The plywood pieces can now be painted and holes enlarged with a 1/32 (.031) drill. I recommend using the middle hole on the rudder and elevator horn, and the top hole on the aileron horns.
- Page 7 Page 7 of 15 Glue the long aileron horns to the TOP of the lower wing. Glue the short aileron horns to the TOP of the upper wing. The top and tail edge of the fuse needs to be glued together with either Foam-Tac or hot melt glue.
- Page 8 Page 8 of 15 Glue the nose cover in place as shown. Use Foam-tac to glue battery Velcro to inside of fuse as shown. (Note, the adhesive on the Velcro is not good enough by its self to hold it in place). Glue Velcro to inside bottom of fuse as shown to hold your receiver.
- Page 9 Page 9 of 15 Solder battery and bullet connectors onto ESC and motor wires. Check to make sure motor is spinning the right direction. Switch any two motor wires to change the direction. Glue Velcro to bottom of main fuse bulkhead as shown.
- Page 10 Page 10 of 15 Glue horizontal stab into the slot in fuse, and glue rudder to the vertical stab. Make sure rudder and horizontal stab are centered, straight and square to the fuse. WAIT with trussing until AFTER control rods are attached. The wire control pieces can be easly attached to the carbon rods with Foam-tac glue and shrink wrap.
- Page 11 Page 11 of 15 To install the elevator control rod. Glue a 9 gram servo in place with the control arm centered straight UP. Attach the control rod to the plywood horn. (bottom hole recommended). Then follow the same steps as the rudder control rod.
- Page 12 Page 12 of 15 Sand the ends of the carbon trussing rods to give the glue a better hold. The upper wing, foam struts, and wing trussing can now be now be glued in place using the tabs and slots provided. Align the wing trussing with the spars in the wing as shown and glue in place.
- Page 13 Page 13 of 15 Glue the lower tail trussing into the slots provided. Glue the upper tail trussing into the slots provided. Make sure horizontal stab is square to the fuse. The motor, prop, and speed control can now be attached to the plane. The servo screws can be used to attach the motor to the plywood.
- Page 14 Page 14 of 15 The bottom of the nose can now be glued in place. Trim off the bottom of the motor bulkhead so that it is flush with the bottom of the nose. The receiver can be attached to the velcro inside the fuse after plugging in the servo wires and binding to the transmitter.
- Page 15 Page 15 of 15 For low rate and maiden flight, the control surface throws for aileron and elevator should be set at 1” both directions, with about 30% EXPO. As you get use to the plane, the throws can be increased. Always do a preflight check to make sure control surfaces are moving in the correct direction.
