Jurca was initially reluctant to design a side-by-side configuration aircraft as he preferred single-seat or tandem-seat 'fighters', but he was convinced to do it by friends and potential customers.
The fuselage is redesigned to accommodate a wider cabin, and the result is a shoulder width of 118 cm (3.87 ft), unusually spacious for this class of aircraft.
The basic design is for a fixed undercarriage, but it allows for electrically or hydraulically powered retractable gear.
[1] Two prototypes have been built, both with electrically-powered retractable landing gear, and with Lycoming O-360 180 hp (134 kW) engines.
