Well done Grueber, it is indeed the AviaSud Mistral, a two-person ultralight bi-plane with forward swept wings. The open, side by side, cockpit is forward of the wings. Designed by two Belgians, Francois Goethals and Bernard d’Otreppe, the Mistral is built (over 200 so far) in Fréjus, France, although until 2004 it was also made under licence in Brazil. The prototype first flew in 1985 and the first production model was delivered in April 1986. The Mistral is powered by a Rotax 582 UL-DCDI unit, although I believe that the Rotax 532 unit has also been used. On 4 May 1987 Nicolas Hulot flew a Mistral to the geographic north pole.
Open house has been declared.
