By 1923 Victor Pisarenko had become one of the best Soviet flight instructors, but in the fall of that year he also made his debut as an aircraft builder and became the first Soviet amateur builder.
With the help of several students, Pisarenko built a single-seater light aircraft in the workshops of the Kacha Flight School, Sevastopol, which had the privilege of being the first Soviet aircraft with a low cantilever wing. This plane received the name VOP-1, an acronym for Victor Osipovich Pisarenko – 1 (Russian: Писаренко ВОП-1).
The VOP-1 was conceived as a cantilever low-wing monoplane built in wood. The one-piece wing with a trapezoidal shape on the plane used a profile selected by the author himself. With a surface area of 10 square metres, it had a double-beam structure and was completely covered by a thin layer of plywood.
The fuselage was built with a wooden structure and had a plywood covering with angular lines. In its central part, behind the engine, the open cockpit for the pilot was located.
The tail was of the monoplane type with the rudders covered in fabric.
The landing gear was conventional, fixed and had a tail skid.
A 35 hp Anzani engine obtained in the workshops themselves was used as the power plant.
The VOP-1 was built in the school’s workshops in Sevastopol and many of its parts were taken from old discontinued models. On November 27, 1923 Pisarenko flew for the first time. This flight was followed by several others.
During the test flights, carried out by Pisarenko himself, the plane was stable in flight and responded well to the controls. With its 35 hp engine, the plane reached a speed of 120 km/h.
