36k b/w "History of aircraft construction in the USSR", Vol.1 p.107;

Single-seat monoplane, intended originally for 40-50hp Ufimtsev, later - for 50-60hp Kalep engine. None of those were used, because 50hp Gnome was acquired.

Aircraft was built well, it was very light. Flying performance was excellent.

Altitude record was set on May 14, 1912 by G.V.Yankovsky - 1775m.
