Rans S-11 Pursuit

The Rans S-11 Pursuit is an American single-engined, tractor configuration, single-seat, low-wing aircraft, based on the lifting body principle, designed and built by Randy Schlitter. The Pursuit was listed as "under development" in 1998, but only prototypes were ever completed and the aircraft is not part of the present Rans aircraft line.
Design and development.
The S-11 was conceived as a unique single seat sport aircraft, based on the lifting body concept pioneered by NASA in the 1960s. The aircraft design derives 80% of its lift from the aircraft fuselage and associated strakes and only 20% from its straight wings.
The Pursuit is a straked, low wing single or dual seat aircraft with tricycle landing gear and dual rudders. It is made from a welded steel fuselage with aluminum ribs and a composite shell. The prototype's engine was a Rotax 912UL of , with the Rotax 582 of intended to be offered as an option.
