Most aircraft built by Dokuchayev were modified Farman designs, each unique. His first aircraft, completed in 1910, was an Anzani-powered biplane of pusher configuration. With 50 hp, the aircraft was tested, but may never have flown. In 1912, he completed a sesquiplane version of a Farman IV, and in 1914 he flew another modified Farman type, this time a trainer aircraft with equal span wings and producing 80 hp with its Gnome-Rhone engine. His fourth model was a return to the sesquiplane configuration, producing a trainer with three rudders operated on skis. Number 5 was a simple monoplane of his own design, but his final design was another Farman modification.
