The Swiss Excellence Risen is a Switzerland two-seat in side-by-side configuration, low wing ultralight aircraft, designed by Italian-Argentine aeronautical engineer Alberto Porto and produced by Swiss Excellence Airplanes. The aircraft was introduced at the 2015 AERO Friedrichshafen show.[1] It is supplied ready-to-fly.[2][3][4]

Design and development

The prototype was completed in 2012 and tested over the next three years before being publicly shown in 2015.[2][5][6][7] The design entered production in mid-2015.[3]

The aircraft has a glass cockpit, motorized canopy, autopilot, retractable landing gear and a ballistic parachute. The main structure is made from carbon fibre. Available engines are 75 kW (100 hp) Rotax 912 ULS and Rotax 912 iS and the 86 kW (115 hp) Rotax 914 turbocharged powerplant.[2]

In 2020 the aircraft's gross weight was increased from 472.5 to 600 kg (1,041.7 to 1,322.8 lb).[4]

Operational history

In 2016 the design set an FAI Class R (Microlights and paramotors) world speed record for absolute speed of 323.82 km/h (201 mph) with a standard Rotax 912 engine.[8] For this record the pilot Alberto Porto, who is also the CEO of Swiss Excellence Airplanes, received an Oscar from VFR Magazine[9] and the De la Vaulx Medal by the FAI.[10]

The FAI records table lists the Swiss Risen as having flown at the speed of 428.18 km/h (266 mph) over a straight course on Jan 22, 2023.[11]
