The Kalinin K-6 was a mail-plane designed by Konstantin Alekseevič Kalinin. It was an aircraft largely derived from the previous Kalinin K-5, which shared its wing, tail and landing gear.[1] This aircraft differed from the previous one by the new fuselage design, which was slender and had a four-meter compartment for the load (370 kg). The K-6 flew for the first time in 1930 but remained at the prototype stage, since mass production was never authorised.
