Tairov OKO-1

Late in 1935 V.K. Tairov helped form the OKO (experimental design section) in Kiev. In 1937 the OKO-1 was completed as a six-seat passenger transport, with all wood construction, this single engined monoplane demonstrated good performance with state-of-the-art systems. Electrically driven flaps, pneumatic wheel brakes, trimmers on all the tail surfaces, heated cabin, lighting and instruments for night or blind flying, full sound-proofing and full GVF(civil air fleet) equipment were all incorporated. The performance of the aircraft in flight tests was regarded as excellent but, for unknown reasons, production was not undertaken.
