esignation S-10 was used for 16 similar airplanes, closely resembling the S-6. S-10 had less powerful engine and generally weaker structure. Two seats were placed side-by-side, and controls could be moved between crew members.
On airplane contest in 1913 this aircraft piloted by G.V.Alekhnovich set Russian record : 500km non-stop flight, staying airborne for 4h56min and 12 seconds. S-10 won the contest, despite as military aircraft it was weaker than S-6A and S-6B, slower and less maneuverable. Its payload 45-48% of aircraft weight was exceptional.
Following year this aircraft was rebuilt for 100hp Gnome Monosaupape engine, and smaller wing. Two S-10 were powered by 100hp Argus engine.
