# Aero Synergie J300 Joker

The Aero Synergie J300 Joker is a French ultralight aircraft that was designed and produced by Sauper/ALMS and later by Aero Synergie. The aircraft was supplied as a kit for amateur construction and also as a complete ready-to-fly aircraft.

## Design and development

The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a strut-braced high-wing, a two seats in side-by-side configuration enclosed cockpit, tricycle landing gear or conventional landing gear and a single engine in tractor configuration.

The aircraft is made from welded steel tubing, covered in doped aircraft fabric. Its 9.04 m (29.7 ft) span wing employs dual parallel struts. The standard engine fitted is the 80 hp (60 kW) Rotax 912UL four-stroke powerplant, with the 100 hp (75 kW) Rotax 912ULS optional.

Originally produced by Sauper/ALMS, the design was later manufactured by Aero Synergie. Production was halted circa 2011, although parts were still available in 2012.

## Operational history

Popular in Europe and Africa as a trainer, it also found use as a personal aircraft due to its simple construction and ease of handling.
