aircraft was capable of in level flight. Under the rules of the time it could not be foot-launched and Pterodactyl advised purchasers to register their Ptigers as experimental amateur-built aircraft With the advent of FAR 103 and the alternate worksheet, the Ptiger conformed and became a legal Ultralight. Ascender II+ The Ascender II+ was introduced in early 1982 and was aimed at the physically larger pilot. This redesigned model incorporated a wider 20-1/2 inch hang cage. All earlier models had a hang cage. It also had stronger upright struts and wing with 1-3/4 inch spars of 0.049 inch thickness, whereas all earlier models used 1-1/2 inch spars of 0.049 inch thickness and heavier 1/8 inch outer bottom cables. The Ascender II+ sold for USD$5260 in 1983. Ascender II+2 The Ascender II+, with its additional structural strength lent itself to the creation of a two-seat trainer version. This was designed by adding an off-center "sidecar" frame to hold the second seat and was named the "Ascender II+2". There was no dual control installation, as both pilots had access to the single side-stick control. The II+2 was first marketed in the middle of 1982 at a price of USD$5560. Light Flyer The final aircraft design and produced by Pterodactyl was based on the Easy Riser wing and was a tribute to the Wright Flyer. The Light Flyer introduced practical improvements over the original Wright brothers design, such as wheeled landing gear instead of fixed skids, allowing taxiing. The aircraft was introduced in 1984 at a price of USD$5400, but only about five were sold. DFE Ascender III-A The Ascender III-A is similar to the original Pterodactyl Pfledge. It lacks a canard and pitch control is by weight shift, although it incorporates some refinements, such as nose wheel steering. The 2003 price was USD$6800. DFE Ascender III-B The Ascender III-B is similar to the Pterodactyl Ascender II with the addition of nose wheel steering and in 2003 sold for USD$7900. DFE Ascender III-C The Ascender III-C is equivalent to the Pterodactyl Ascender II+ with the heavy-duty style airframe. It sold for USD$8100 in 2003. Like the Ascender II+, the Ascender III-C can be fitted with a sidecar to become a two-seat trainer version. DFE Ascender III-T The Ascender III-T is similar to the Pterodactyl Ascender II Ptug hang glider tug aircraft and incorporates a bridle to fit around the propeller to attach the
