Design and development

The aircraft complies with the Fédération Aéronautique Internationale microlight rules. It features a cantilever low wing, two seats in a side-by-side configuration enclosed cockpit, a choice of tricycle landing gear or conventional landing gear and a single engine in tractor configuration.[1]

The aircraft has a wooden airframe covered in doped aircraft fabric. Like most Jodel designs its 7.5 m (24.6 ft) span wing employs dihedral in the outer half only. Standard engines used are the 100 hp (75 kW) Rotax 912ULS four-stroke and the 85 hp (63 kW) Jabiru 2200 powerplant. Other engines of similar power output can also be used.[1]

Reviewers Robby Bayerl et al. describe the aircraft as possessing "great performance and impeccable behaviour in flight".[1]
