Mi-35

The Russian Mil Mi-24 helicopter has had a large number of variants.

The Mi-24 (Russian: Миль Ми-24; NATO reporting name: Hind) went from drawing board in 1968 to first test-flights in less than eighteen months. The first models were delivered to the armed forces for evaluation in 1971. The Hind-A did have a number of problems: lateral roll, weapon sighting problems, and limited field of view for the pilot. A heavy redesign of the aircraft front section solved most of these problems.
