Single engine trainer aircraft

​

    In 1931 a single R.S.V. 26/180 Mark III was modified to be powered by what was to become one of the Aéronautique Militaire's standard power plants, the Armstrong-Siddeley Lynx of 215 hp. As development was conducted at the Deurne's based Stampe Vertongen company and as both S.V. and Renard went separate ways, the unique machine was designated Stampe Vertongen SV-26/215 Lynx. Some contemporary literature also mistakenly identified this aircraft as the S.T.26.
