Development of Gakkel-IV. Wing span was increased again, another pair of struts was added. Upper wing was larger than the lower one, ailerons were huge - 4m2 each. Passenger/trainer seat was added. Radiator, originally installed behind the engine, was moved under the fuselage.
Ya.M.Gakkel learned how to fly itself on this airplane. Several flights were performed by B.F.Bulgakov, S.A.Ulijanov and G.V.Alekhnovich (who obtained pilot's license flying 'Gakkel-VI'). Flights by G.V.Alekhnovich between Gatchina, Krasnoe Selo and Tsarskoe Selo became the first city-to-city flights in Russian history.
Aircraft was transferred to Korpusnoe Pole before September 1, 1911 to participate in First Contest of Russian Military Airplanes. During preparations to the contest aircraft was modified again and designated Gakkel-VII.
