strut-braced
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in ...

high-wing
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes.
A monoplane has inherently the highest efficiency and lowest drag of any wing confi ...

Design and development
The Fergy was developed from the

The Kolb Mark III is a family of American side-by-side two seater, high wing, strut-braced, pusher configuration, conventional landing gear-equipped ultralight aircraft that is produced in kit form by New Kolb Aircraft of London, Kentucky, and ...
and introduced to the market in 1991. Reviewer Andre Cliche describes it as a "clone", whilst Noel Bertrand et al. claim it was "inspired by the Kolb Twinstar". The aircraft differs from the Kolb design in that it has a revised cockpit pod, with centerline-hinged doors and a square-tipped rudder. The
