Design and development
The GT500 was developed specifically for the Sportplane class of the primary aircraft category (Part 21.24 of the Federal Aviation Regulations) and, on 26 July 1994, became the first aircraft certified in that category. Reviewer Noel Bertrand wrote, "[It] may sound like a very dry achievement, but actually speaks volumes for its design integrity. Not surprisingly its flight behaviour is excellent." The aircraft's nomenclature is unclear as the manufacturer refers to it variously as the ''GT500'', ''GT 500'' and the ''GT-500''. The FAA certification officially calls it the ''GT500''. The GT500 is constructed from aluminium tubing, which is bolted together. The aircraft is covered in pre-sewn Dacron envelopes, with the forward fuselage made from fiberglass. The wing features half-span ailerons and half-span flap (aircraft), flaps. The GT500 has two seats in tandem, with dual controls featuring control columns with Yoke (aircraft), yokes. A 1991 upgrade included optional doors that are zippered into place adding of cruise speed, steel landing gear legs with dual brakes and an electric starter.Variants
