Design and development

The Sirocco nG features a V-strut-braced high-wing, a single-seat open cockpit, fixed tricycle landing gear and a single engine in pusher configuration.[1]

The aircraft is made from composites. The nG model, which first flew in May 2009, has an all-new composite wing of shorter span, 9 m (29.5 ft) and an area of 12.15 m2 (130.8 sq ft), with ailerons that replace the earlier spoilers. The fuselage is all composite. The standard engine used is the 33 hp (25 kW) B&S V-2 four-stroke powerplant. Electric power has also been an option since 2012/13.[1]

The design rights to the Sirocco series are currently held by Evert Cornet of AC Light Aircraft.[1]

Operational history

The original Sirocco was the first ultralight aircraft flown around the world, completing the flight in the 1980s.[1]

Reviewer Marino Boric wrote about the nG design in a 2015 review, saying, "the cockpit offers good crash safety. Very low stall speed, short take-off and landing and efficient controls all contribute to the Sirocco's appeal."[1]
