Dalotel DM-165
The fuselage top box section (above left) covered with F1 and F2. Cutouts are for weight saving. Note the bellcrank and elevator pushrod. Formers B through
ing edges and the elevator leading edge and round off. Join the two elevator segments to- gether with a ¼-inch dowel. Seal all raw edges with gummed paper tape. Hinge the elevators to the stabilizer with flex hinges at four places. Wing: Make the left and right wing spar sections from ¼-inch balsa capped with 1⁄4 square spruce strips. Join the spar seg- ments together with 1⁄8-inch ply joiners, front and back, making sure to maintain the correct dihedral. Glue the 1⁄8-inch ply gear mount into the bottom of the right wing panel. Glue the wing spar into the right wing panel.
D are in place (above right), with the centerline balsa stringer. The centerline stringer aids in keeping the top fuselage deck a uniform pattern.
The wing ribs 1 through 7 are then added,
with the ribs at the ply spar joiners being shortened by 1⁄8 inch to account for the join- er thickness. Add cardboard doublers (4 pieces) over each ply gear mount. Glue a one-ounce weight to the right wing tip. The top wing panel on the plan is slightly oversize, so fold the top wing panel over and trim it to fit the bottom wing panel. 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 fash- ion. 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. Each fuselage piece has a fold line aft of the wing. Line the upper and lower edges of each fuselage side with 1⁄8 × ¼-inch balsa strips, as shown in the fuselage side view. The strips are recessed 1⁄8 inch in from the fuselage edges, except over the wing saddle area where the strips are flush with the edge of the fuselage.
