was not a production success and few were built, but the NFL paved the way for the Ptraveler and Ascender to follow. Ptraveler McCornack had first installed a canard elevator on a Pfledge in 1978, but did not create a production model until 1980. The canard was operated by a side-mounted control stick. Fore-and-aft movement of the stick moved the canard and sideways movement controlled the tip-rudders. The canard was constructed with tubular spars, aluminum ribs and covered in standard aircraft fabric. In the Early 1980s a Pterodactyl pilot named Jeff Ballas attended the Sun-N-Fun fly-in and was impressed with the mylar covering on the Lazair. He bought a roll of mylar and some tape, went home and re-covered his canard with the clear mylar. This experiment was a success. The handling of an Ascender with the lightweight mylar was much lighter and increased the nimble feeling of the aircraft. The new model carried the name "Ptraveler", continuing the use of the silent letter "P" in Pterodactyl designs. The new model was powered by the Cuyuna 430D direct drive engine and was introduced in 1980 at a price of USD$3900. Ascender The Cuyuna 430D powerplant was greatly improved by the addition of a 2:1 belt reduction drive, allowing larger propellers of 54 inches diameter to be used. This produced more thrust and less noise. The modified powerplant was called the Cuyuna 430R. Fitting the new powerplant into the Ptraveler drastically improved the aircraft's take-off and climb performance. The new model was named the "Ascender" for its improved climb rate and also in tribute to the Curtiss-Wright XP-55 Ascender, an early canard fighter design. In 1981 a complete kit cost USD$4200. Ascender II The Ascender II was an improved Ascender with evolutionary changes incorporated. It had an improved muffler, re-located throttle and fiberglass spring rod main landing gear suspension. Psounder The Pterodactyl Psounder was a one-of-a kind Ascender II that was modified for an atmospheric research project at Colorado State University. Ptug The Ptug was a special hang glider towing version of the Ascender II that was modified with a special rigid bridle to ensure that the tow rope stayed clear of the propeller. Ptiger By adding a fiberglass tub in place of the basic Ascender II+ airframe, along with clipping the wing by to a span, the result was a new model named the "Ptiger". With the Cuyuna 430R the
