Rebuilt Gakkel-II. Except new more powerful engine, a lot of innovations were introduced. Wing spars were machined to have 2-T profile (commonly used were ones of rectangular cross-section). Piano strings were used for tension wires. Fuselage was covered with fabric - unlike commonly used bare structures.
Pair of A-shaped struts linked together wings and fuselage, to the lower ends landing gear were attached. In addition to commonly used vertical amortization (rubber) transversal amortization was introduced as spiral springs on both sides of the wheels.
Wings had S-profile (skin - rubber coated fabric), carried no ailerons. Roll control was performed by wing wrapping (common practices at the time).
Aircraft was finished in May 1910, taxi tried on a hippodrome. First flight took place on May 1910 at Gatchina airfield near St.Petersburg. It was the first registered flight (~200m long) of airplane built in Russia. Later it was found that first flight was performed by A.S.Kudashev in Kiev just a day before...
But unfortunately the last one was performed without proper notification and was not registered.
The Anzani engine had a poor performance - it overheated too quickly, so no any continuous flights were performed. S-profile also did not prove to be suitable for the wing, and later was not used.
Gained experience allowed to build the Gakkel-IV.
