Note:- There is much confusion as to the number of aircraft produced. I am firmly of the opinion that only one was built, and the confusion arose from someone,at a later date, adding -1 and -2 to the S to denote single engined and twin-engined. If there was evidence that two aircraft had been built then I am sure that Bill Gunston would have cited it in his 'Encyclopaedia of Russian Aircraft'.Petebutt (talk) 20:18, 4 July 2009 (UTC)Reply
