Major performance increases are possible on several sailplane models (proven on some power aircraft as well) by the addition of turbulators placed ahead of the separation bubble on the wing. Turbulators are found on most current production sailplanes as delivered by the manufacturers. Wings and Wheels offers multiple types of turbulator tape.
