The S-12 was built at the suggestion of George Yankovsky as a lighter, single-seat version of the S-11 with an 80hp Gnome. He looped it in September 1913, the first time a Russian aircraft had performed this manoeuvre, and set a Russian height record of 3680m shortly afterwards. Most of the dozen or so S-11s that were built survived the war, and served in the earliest Soviet Air Force units during the Revolution. Several were still operational in 1922, mostly with an 80hp Le Rhone engine.
Developed from the larger and heavier S-9, the 1913 S-11 Polukroogly (half-round) had a conventional wooden fuselage and 100hp Gnome Monosoupape engine. It was initially equipped with ailerons that were operated by steel tubes inside the wing. Trials revealed that they were not efficient, so they were replaced by wing warping. The pilot and observer sat side-by-side, with controls only for the left seat. A top speed of 100km/h, stalling speed of 70km/h and take-off run of 75m were good enough to gain the S-11 second place in the 1913 military competition for a reconnaissance aircraft; but it was not ordered into production.

Constructed in Kiev, this 100 hp Argus-powered biplane was used by Igor Sikorsky to set new Russian flight records in November 1911, even setting a world-record with his design – a distance record with two passengers.
Under the designation S-10, about sixteen production versions of the S-6B were built by the RBVZ. The majority were delivered as twin-float seaplanes for service with the Baltic Fleet, from the summer of 1913 to 1915, with 100hp Argus or Gnome Monosoupape engines. Some were deployed on the world’s first operational seaplane carriers.
A special Competition S-10 landplane, with 80hp Gnome engine, was built for the 1913 military aircraft competition. The wing span was increased to 16.75m, with outer panels that could be folded for storage. The two seats were placed side-by-side, and the control wheel could be swung from pilot to co-pilot during flight. Production test pilot Alechnovich set a Russian record by flying it 500km in 4 hours 56 minutes, and it took first prize in the 1913 competition although it lacked the speed and manoeuvrability of the S-6B. After its span had been reduced to 13.70m and a 100hp Monosoupape installed, it served as a trainer with the Baltic Fleet.
The S-10A’s span of 13.7m and two seats in tandem set the standard for all S-10 seaplanes, and its 125hp (de-rated to l00hp) Anzani engine gave it better speed and rate of climb than the Competition S-10. Its flying characteristics were less good, preventing it from gaining first prize, but it set a new Russian height record of 3420m, piloted by Gleb Alechnovich. Modified to have a 100hp Monosoupape and floats, it was assigned to the Baltic Fleet.

Russia
The large Russian engineering company, Russo-Baltic Waggon Works, based at St Petersburg, was only partly concerned with aircraft production. It was responsible for the construction of the ll’ya Muromets series of four-engined bombers, designed by Igor Sikorsky, which equipped Russia’s Eskadra Vozdushnykh Korablei (Squadron of Flying Ships) in First World War. Largest of the series was the Type IMYe2, with a wingspan of 34.50m and a gross weight of 7,000kg. The Sikorsky S-16 reconnaissance biplane was also built.
The Russian Gyroplanes Gyros-2 Smartflier autogyro was designed for a variety of roles, including aerial application, courier, forestry patrol, search and rescue, geological survey, air taxi and flight training. It features a single main rotor, a two seats in side-by-side configuration enclosed cockpit accessed by doors, tricycle landing gear, plus a tailwheel and a 200 hp (149 kW) Mistral 200 engine in tractor configuration.
Russian designed and produced by Russian Gyroplanes of Zhukovsky, Moscow Oblast, the aircraft is supplied complete and ready-to-fly.
The autogyro has a two-bladed rotor and a three or six-bladed tractor propeller. The autogyro also fits an optional Racket 120 single-cylinder, two-stroke auxiliary engine for running the agricultural equipment, when it is installed.

In Russia they built several small dirigibles including the “Mikst” in 1911. Built by A.I. Shabsky.
In fall 1920, in Salizi Village in the Leningrad Region, they began to assemble a French-produced airship they renamed into Krasnaya Zvezda.
A flight of the airship ended with a crash because of the wind and defects in the airship construction. Its gondola tore off the airship hull.
It was disassembled in 1936.
