The aft fuselage pieces complete the bottom fuselage. F10 (above) is scored and folded to conform to the fuselage curved shape. The bellcrank (at right) and fuel tank are attached to 1⁄8-inch ply supports, which are glued to cardboard supports. The tank is held in place with rubber bands. The pushrod is made from 1⁄4-inch square spruce.
Apply glue to the top of the wing spar, the top of the ribs and the trailing edge of the wing and fold the center top wing surface down and pin securely in place until dry. Build the left wing panel in a similar fashion. Add the balsa tips to the wing and sand to shape. Make a line guide from 1⁄8-inch ply. Cut slots in the left wing balsa tip and glue the line guide in place. Cover the trailing edge and all seams with gummed paper tape.
Fuselage: The flat fuselage sides are out- lined with a triangular symbol on the draw- ing. Line the upper and lower edges of each fuselage side with 1⁄8 × 1⁄4-inch balsa strips,
as shown in the fuselage side view. The strips are recessed 1⁄8 inch in from the fuse- lage edges. Now cut out the section of the aft fuselage side above the horizontal stabilizer saddle position and save these pieces for later.
Add cardboard supports to each fuselage side below the bellcrank and above the fuel tank. Be sure and cut holes in the left fuse- lage side for the bellcrank leadout lines and pushrod exit. Note that each fuselage side is scored and folded in two places, one forward of the wing and one aft of the wing. Make the firewall, A, from 1⁄4-inch ply. Lo- cate the mounting holes for the KM40 motor
mount on the face of A. Drill the mounting holes and install blind mounting nuts on the back side. Drill a hole in A for a fuel tubing exit. Drill two holes in A and install blind nuts on the back side. These holes must align with the holes in C1 and are used to at- tach the removable bottom cowl section. The following method should be used to glue the firewall A in place. First, glue the nose gear ply mount to F7. Then lay the right side fuselage panel flat on the work board. Prop up the front end of the fuselage nose by adding a piece of scrap cardboard 0.25 inches high under it (see construction photo). This will give the proper cant to the
