[1] Two years previously, the firm had introduced a training biplane for the Belgian Air Force that also had a wing area of 26 m2 (280 sq ft); powered by a 75 kW (100 hp) engine, it had been designated the RSV.26/140.

[4] At the time, Wright Tuttle Motors was negotiating a license to build the Renard Type 100 engine in the United States.

[10] Gates was an exponent of light aviation and was so interested in the type that he not only purchased the first RSV.26/18, but a few weeks later, bought a license to produce it in the United States.

[10] However, only two aircraft were built[11] before the Wall Street crash of 1929 ruined the company and Gates himself, who committed suicide as a result.

[1] After George Ivanow joined the firm, he made one final attempt to market the design, modifying the RSV.18/100 (OO-AKG) to use a de Havilland Gipsy III engine[12] and rebuilding the fuselage and empennage along similar lines to the SV.4.
