forward fuselage. Now glue the firewall A in place making sure it is at a right angle to the work board. Glue the ply gear mount and F7 in place, which locks in the proper cant angle.
Glue the left side of the fuselage to fire- wall A and the ply mount and F7. Add fuse- lage bottom piece F8 and the main gear ply mount in the bottom fuselage. Add F9 and F10 to complete the bottom fuselage. Note F10 is scored and folded near the aft end to accommodate the fuselage curve. Attach the fuel tank to the 1⁄8-inch ply sup- port with rubber bands. Make a pushrod from 3⁄32-inch wire and 1⁄4-inch square spruce and attach it to the bellcrank along with the leadout wires. Install the tank and bellcrank assemblies by gluing the ply supports to the
cardboard supports on the insides of the fuse- lage. Glue the stabilizer support F6 in place. Test fit the stabilizer in place and remove cardboard around the 1⁄4-inch dowel joiner to allow for smooth action of the elevators. Glue F1 through F4 in place. Note that F5 has two slot cutouts to accept the tabs in the fin root. F1 and F2 have lightening holes for weight savings. Be sure to bring fuel tubing fill and overflow lines out during all cover- ing operations. Add fuselage former B to the top forward fuselage, adding a 1⁄8 × 1⁄4-inch stringer down their centerline.

The cowl is made in two pieces, a fixed up- per piece glued to the fuselage and a remov- able lower piece for access to the engine. The
upper rear cowl is built-up from 1⁄2-inch bal- sa sheet sides and carved to shape. The front of the upper cowl is 1⁄2-inch balsa sanded to shape. The removable bottom half of the
cowl is made in the same fashion, but 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. Test fit the en- gine in the cowl and drill the mounting holes. Use a shaft extension on the engine to give adequate spinner clearance. Cut holes in the cowl block for the cylinder head, ex- haust and needle valve. Apply epoxy to the inside of the cowl and front of the firewall. Seal all joints on the fuselage with gummed paper tape.
Make the main gear from one piece of 1⁄8- inch diameter wire as shown. The wire is
The nose gear strut is bent to shape from 1⁄8-inch wire (at left) and attached to the ply mount with nylon gear clips. The main gear (above) is 1⁄8-inch secured to the ply mount with four nylon gear clips.
