Farman-IV on the ground (50k) from "History of aircraft construction in the USSR" , Vol.1 p.142;

The most widely used and popular ' Farman' in Russia during 1909- 1916. Hundreds of Russian aviators made their first flight on Farman-IV.

Only few Farman-IV's were purchased in France. But many hundreds were built at various workshops and factories, ranging from homebuilts to large batches from Dux and other serious manufacturers. As a result total number of built aircraft and its modifications are unaccountable. Most of them were powered by 50hp Gnome engine.

Description provided by prof.N.A.Rynin: 3-strut biplane with tail frame. Engine is mounted on the lower wing, driving pusher propeller. Ailerons had only lower control cables and were hanging down while aircraft is in rest. Aircraft is built of wooden elements, connected by very basic joints and enforced by bracing wires.

Wing was covered with fabric only from below. As a result wing had 'not an airfoil but something unimaginable', as pilots giggled. But it was fine, thanks to very small wing load.

The most common modification of F-4 included two-side fabric cover on the wing and ribs with more advanced airfoil. Those basic improvements, first performed by Russian aviators, allowed pilot M.A.Gaber-Vlynskij to set several ceiling records (April 13, 1913) :

  • pilot with 5 passengers - 1120m
  • pilot with 4 passengers - 1350m
  • pilot alone - 3000m
  • Some Russian Farman-IV's were built of bamboo instead of pine. During winter season wheels were replaced by skis.

    Aircraft was not used for military purposes.
