panel tapered spar) from 1⁄4-inch balsa capped top and bottom with 1⁄4-inch square spruce strips. Join the three spar segments together with 1⁄8-inch ply joiners fore and aft, making sure to maintain the correct dihe- dral. Glue the center wing spar into the cen- ter wing panel. Glue two cardboard ribs W1 into the center wing panel.
The top wing panels on the drawing are purposely shown slightly oversized, so fold them over and trim them to fit to the rib edges and wing trailing edge. When trimmed, 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 pan- el down and pin securely in place until dry. This completes the center wing section. Glue a 1⁄8-inch ply gear mount into the bot- tom of the right outboard wing panel. Glue the right side spar into the bottom of the right hand outboard wing panel. Add ribs W1 through W6. Add cardboard doublers over the ply gear mount. Glue a one-ounce weight to the right wing tip. Fold the top wing surface down, trim as re- quired to fit and glue in place. Build the left outboard 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 a slot 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
The fuselage sides are lined with balsa strips recessed 1⁄8 inch from the edge and have cardboard supports to secure the plywood bellcrank and fuel tank mounts. The ply firewall has blind nuts for the engine mount and dowels for the cowl attachment.
strips are recessed 1⁄8 inch in from the fuse- lage edges except over the wing where the strips are flush with the fuselage edges. Bev- el the strips at the aft end of the fuselage so that the cardboard sides will come together. Add cardboard supports to each fuselage side at the fuel tank and bellcrank locations.
Be sure to cut holes in the left fuselage side for the bellcrank leadout lines and pushrod exit. Note that each fuselage side is scored and folded in one place, aft of the wing. Make firewall A from 1⁄4-inch ply. Locate
the mounting holes for the KM40 motor mount on the face, then drill mounting
