Remarks by Walter van Tilborg: "Designed by Paul Frank Seales of Houston, Texas, this two-seat sport aircraft was of mixed construction with a welded steel tube fuselage and aluminum alloy wing ribs, while the wing tips, wing root fillets, rear cabin fairing and engine cowlings were made of glass fiber. The type featured foldable wings as standard and it had a tail wheel type landing gear. It was marketed as kit, initially by ProTech Aircraft Inc. of Richmond, Texas, but in 1992 the production rights were acquired by ProStar Aircraft Inc. of Beeville, Texas.

PT-2 Sassy: This was the prototype built by Frank Paul Seales, Houston. Registered N211PT on March 10, 1986, the aircraft first flew in June 1987, initially fitted with a 75 hp Revmaster 2100-D engine, later with an 150 hp Lycoming O-320 engine.

PT-2A ProStar: The initial model as offered for amateur construction. It was suited for Continental engines in the 64 to 100 hp range. This first variant was largely based on the prototype.

PT-2B ProStar: This improved version, first built by ProTech, had STOL performance, flaperons, large cabin doors and a recontoured windscreen for improved pilot visibility. The PT-2B was also stressed to accept engines in the 85 to 135 hp range.

PT-2C ProStar: The PT-2C was introduced by ProStar and had a generally beefed up construction for more powerful engines in the 115 to 160 hp range, including Lycoming and Canadian Air Motive types. The prototype PT-2C (modified from the original prototype) used the 150 hp Lycoming O-320 and first flew during 1995. This model also had increased wingspan and fuel capacity.

Over 100 kits were sold to customers in Australia, Canada, Italy, Mexico and the USA. Many of those were flown, in the USA alone 46 have been registered."
