The Mil's Flying Egg V-7.

Russian Mil company, known for creating helicopters, began designing its small, four-seat helicopter to be used as an "air taxi", which should help civil transportation on the vast distances within the Soviet Union in 1953. Military application as an artillery corrector was also considered.

The Mil V-7 appeared as a four-seat helicopter with ramjets at the tips of the two rotor blades. It had an egg-shaped fuselage, skid undercarriage, and a two-bladed tail rotor on a short tubular tail boom. Only one flyable prototype was completed in the late 1950s.

Its first test flight took place on 10th February 1962. The helicopter made a remotely controlled takeoff and landing on a leash.

The tests demonstrated poor result and the engines were damaged. It took another three years to resume the trails. By that time conventional design with a main rotor and tail blades proved to be far more reliable and efficient.

The test flights were canceled as the whole project closed in 1965. The only fully completed V-7 helicopter can be seen in the museum of the Russian Air Force in Monino, Moscow Region.
