The Pipistrel Sinus is a single-engine ultralight, motor glider developed by Pipistrel.[1][2]

Development[edit]

The development of the Sinus began in 1994 in close collaboration with the Slovenian firm Alabastar Ltd. A year later, the Sinus was unveiled at AERO Friedrichshafen 1995, with first flight of the prototype taking place in 1996.

In 2001, Philippe Zen and Thomas Knowles flew a Sinus at the World Air Games in Spain and won first place in the two-seat category.

Design[edit]

The Sinus is a two-seat, ultra-light, high-wing, cantilever monoplane. It is primarily built from composite materials and is capable of soaring. The variable-pitch propeller (Pipistrel VARIO) can be feathered in order to diminish the air resistance in non-powered flight.[3]

The Pipistrel Sinus comes with either nose-wheel or taildragger landing gear. Engine models available are the Rotax 503, 582 and 912.

Variants[edit]

Sinus 447
Rotax 447 powered variant for the Slovenian market.
Sinus 503
Rotax 503 powered variant with a variable-pitch folding propeller.
Sinus 582
As the 503 but fitted with a Rotax 582.
Pipistrel Sinus 912
Sinus 912

Sinus FLEX
Option features two wingtip sets to convert from motor glider to sport cruiser in minutes. With the short wing tips the aircraft is the same as the Pipistrel Virus. The wing tips can also be used on any existing Sinus and not just new-built aircraft.[4]
