The rear seat has very limited visibility.
The aircraft is made from wood with its flying surfaces covered in doped aircraft fabric. Its span wing employs single supporting struts. The standard recommended engine is the JPX 4T two-stroke powerplant or a Volkswagen air-cooled engine. The Souris Bulle has a glide ratio of 18:1.
The standard day, sea level, no wind, take off with a engine is and the landing roll is.
In 2015 the aircraft kit was €13,300 and plans sold for €380. The manufacturer estimates the construction time from the supplied kit as 650 hours.
