Quote: "Stuntster, by J Richards.

In designing this ship, we tried to combine good looks and originality with ease of construction and all-around performance. The tapered wing sets the model off from the all-too-common 'barndoor' stunter, while the rakish lines suggest a modern fighter plane.

The plane can be powered by a McCoy 19 or any similar engine ranging from .14 to .23 cubic inch displacement. The engine cowling is simple and efficient, leaving the cylinder head and exhaust stack exposed to facilitate cooling and accessibility. So, if a simple, realistic stunt model appeals to you. let's start construction.

WING: Following the full-size patterns shown on the plans, make the root and tip rib templates of 1/8 plywood and drill the leadout holes. Stack eight balsa rib strips of 1/16 sheet between the root and tip templates, and pin together through the lead-out holes. Carve and sand the stack to conform to the templates, notching ribs for leading edge and top and bottom spars. Separate ribs when completed, and repeat procedure for other half of wing.

Lay bottom spar down and cement ribs in position. Install top spar and leading edge, and cement entire structure liberally. Cut tip blocks out of soft scrap balsa, and cement in position. Drill left tip, and install 1/2 in aluminum leadout tubes. Add bottom trailing edge and bellcrank floor. Bolt a 3 in Veco or similar bellcrank in position, and install the leadout wires.

The bottom wing sheeting and cap strips are now added, and a 11/2 ounce lead weight is installed in the right wingtip. Cement the top sheeting, cap strips, and trailing edge in place, and carve and sand the tip blocks to shape. Connect the pushrod to the bellcrank, and plank the center section of the wing, cutting the pushrod slot in the upper surface.

FUSELAGE: Cut the fuselage sides from hard 1/8 sheet balsa, and cement together at rear. Cement the hardwood motor mounts in position and then install the engine. Cut formers A and B from 1/2 in plywood. Notch former A for motor mounts, and drill for fuel line. Drill former B for the landing-gear retaining bolts.

Bend the landing gear from 3/32 music wire, add 2 in K&B or similar wheels, and install it on former B with retaining J-bolts. Slip former A and B in position, and use enough cement to hold them firmly in place. Now complete the fuselage structure by cementing the crossbraces in place. Install the stunt tank and connect the fuel line, leading the line through the firewall to the engine. Drill holes for the needle valve, and tank drain and filler... "
