This brainchild of Roger Druine is so good that Rollason Aircraft in England and Flugzeubau in Germany started manufacturing them. The Turbulent's airframe is an all-wood structure covered with fabric. It uses a box spar with a built-up rear spar, conventional ribs, and a plywood-skinned leading edge forming a rigid D section. A happy feature of the Turbulent wing is leading edge slots and Friese-type ailerons that bring the stall down to around 29 mph with full aileron control all the way. Volkswagen engines from 30 to 40 hp are commonly used.
