Some other features are also unusual: it has a wing which folds for transportation by horizontal rotation through almost 90° and a single engine mounted high on the fin in tractor configuration.

Instead of conventional hinged flaps, the inner 2⁄3 of the trailing edge can be extended rearwards, exposing new fabric surface stored within the wing in roller blind fashion.

[3] The fin and rudder together form a swept, short and parallel chord surface which carries at its top both the tailplane in T-tail configuration and the engine.

In elevation it has a curved underside and, above, the large one piece canopy over the side-by-side, dual control cabin forms an unbroken line with the fuselage.

[1][3] A full-size mock-up appeared at the Friedrichshafen Aero '07 show in April 2007, and the prototype flew in August 2007 at Chambery.

[3] In March 2012 the company was pursuing light-sport aircraft approval of the design to facilitate sales in the United States.

This change enabled shortening the main landing gear legs to improve cockpit visibility when taxiing.
