Flat fuselage sides are lined with balsa strips recessed ¹⁄₈-inch and have cardboard supports for the bellcrank and the fuel tank ply mounts (above). Note the cutouts for the flying wires and the elevator pushrod. The ply firewall has blind nuts for the KM40 engine mount and cowl attach. The bellcrank and fuel tank (at right) are attached to ¹⁄₈-inch ply supports. The fuel tank is held in place with rubber bands.
and bellcrank assemblies by gluing the ply supports to the cardboard supports on the insides of the fuselage. Glue the fuselage sides together at the
tail. Glue F1 through F4 in place to cover the top fuselage. Be sure to bring fuel tub- ing fill and overflow lines out during all covering operations. Cover the bottom fuselage with F6 and F7. Note the gap be- tween F6 and F7 for the ¹⁄₈-inch ply tail wheel support. Glue former J to the bottom forward fuse-
lage, add a ¹⁄₈ × ¼-inch balsa stringer down the centerline to A and cover with decking piece D4. Add fuselage former B to the top forward fuselage, add a balsa stringer down the centerline to A and cover with decking piece D1. Add formers B through D to the
top forward fuselage, add a balsa stringer and cover with decking piece D2. At this point, the horizontal/elevator as-
sembly is glued in place on the aft fuselage. Glue formers E through I in place to the top aft fuselage. Note that former I is located on top of the horizontal stabilizer. Add a cen- terline balsa stringer and cover with deck- ing piece D3, which is notched to go over the stabilizer. Complete the forward cockpit windshield by gluing W1 in place. W1 is made from thin manila folder cardboard with a ¹⁄₈ by ¼-inch balsa strip glued down the centerline for support. The cowl is built up from ½-inch balsa
sheet and carved to shape. The top half is glued to the model while the bottom half is removable. The removable bottom half of
the cowl has a ¹⁄₈-inch ply C1 former glued to the back. The two holes in C1 must align with the blind nuts in the firewall A. Sand, carve and hollow the cowl to shape. Test fit the engine in the cowl and drill mounting holes. Use a ½-inch shaft exten- sion to give adequate spinner clearance. Cut holes in the cowl block for the cylinder head, exhaust and needle valve. Apply epoxy to the inside of the cowl and front of the firewall. Glue the rudder to the fin with the trail-
ing edge offset ½ inch to the outside of the flying circle and glue in place. Add carved balsa fairings on each side of the fin to com- plete the aft fuselage. Glue the wing to the fuselage. Make each main gear from ⁵⁄₃₂-inch diam-
