Designed and built in the Czech Republic, originally by Wolfsberg Letecká Továrna (WLT) which was renamed Wolfberg Aircraft in 2017.
[2] The Sparrow's fuselage has a smooth profile partly defined by multipanel glazing that extends almost from the nose back beyond the wing leading edge.
The aircraft is normally flown from the front; the rear seat, placed over the leading edge, can also be provided with controls and instrumentation for an instructor (the Trainer version) or, as on the Clubman, be a passenger position.
[2] French certification was obtained in January 2014[4] and it appeared on public display for the first time at the AERO Friedrichshafen show in 2014.
The display example is a later version powered by a 75 kW (100 hp) Rotax 912 ULS flat-four, air- and liquid-cooled engine.
