The Tigress was intended to be a development of the Lancair IV adapted to employ the 600 hp (447 kW) Orenda OE600 V-8 engine, giving it a cruise speed of 405 mph (652 km/h).

The engine was later cancelled by its manufacturer, Orenda Aerospace, and the Tigress kit was not produced as a result.

[1] The aircraft featured a cantilever low-wing, a four-seat pressurized cabin, retractable tricycle landing gear and a single engine in tractor configuration.

With full fuel of 115 U.S. gallons (440 L; 96 imp gal) the payload for pilot, passengers and baggage was 310 lb (140 kg).
