10/31/2023. Remarks by Johan Visschedijk: "During the time of its existence (1920-1947), the Waco Aircraft Company of Troy, Ohio, produced 3,723 aircraft (excluding the WW II gliders), 300 of which were Waco NAZ gliders.

Also referred to as the Primary Glider, the type was a single-seater with a fuselage constructed of steel tube. Internally braced with hard wire the wings were built of spruce spars and web ribs, and were fabric covered. The landing gear consisted of a curved main skid made of Hickory wood that was fixed to the bottom of the fuselage. A steel tube skid was fastened to a tripod and fixed under each wing tip.

The NAZ could be launched by a winch, bungee cord, car, or aircraft. The glider could reach speeds up to 65 mph (105 kmh), had a 14-to-1 glide ratio and had a landing speed of ca. 20 mph (32 kmh)."
