About this Plan

Sleekster. Control line stunt model.

This plan was printed in Flying Models Decade of Designs (1), published 1960.

Quote: "Sleekster is an advanced stunt model, designed to perform with the best of them at contests, and yet appeal to builders who take pride in the appearance of their planes. The design and finish of the Sleekster is by the writer, the construction by Don Bolger.

Large area, thick airfoil, and just the right amount of flap area gives the Sleekster the ability to perform tight maneuvers with ease and smoothness. Yet, the design is clean enough so that ample speed is maintained with .29 to .35 displacement engines.

Ready to start construction? First, get a piece of wrapping paper and enlarge the quarter-scale plans to full size. This really isn't very hard, even without mechanical drawing experience. All ribs are shown full size. To get the complete templates for the ribs and for bulkheads #1 through #5, the fold and trace method is used: Fold some tracing paper and place the fold on the center-line on the plan. Then, trace the outline of the ribs, cut out the traced outline, and unfold the paper.

Fuselage: First, lay out two sides, using 3/16 square hard balsa. Fill in the sides with 3/16 sheet balsa, to Former #3. Then, connect the sides together with 3/16 square cross-pieces, cement all bulkheads into position, and add the planking. Five 1/8 square stringers are used on the turtle-back and two 3/16 stringers fair the bottom of the fuselage.

Cut the team-racer type gear from 24-ST aluminum, and bolt it to the 1/8 in plywood anchor. Both the gear anchor and the 1/2 x 1/4 x 6 in maple engine mounts are fixed in place with Weld-wood glue or fuel-proof cement.

The bottom of the cowling is carved and hollowed from a 2-3/4 x 2-3/4 x 2-1/4 in balsa block. The top of the cowl is carved from a 1-1/8 x 2-1/4 x 7 in block. Since the cowl top must be taken off for refueling, it is keyed with little blocks or dowels, and held in place with a small bolt. Solder the nut to 1/32 brass shim stock, bolted to the back of the engine. The cowl is faired into a 2 aluminum or plastic spinner..."
