The road to the Black Shark!

Hello,

 

Apparently, it started in 1975 with about half the payload and half the weight as a two seat design. It then went through further single seat iterations (competing with the V-100 paper design), including a four winged version, before finally being built. Really quite interesting,

 

I found someone who has good references and knowledge about these Kamov helicopters. We are discussing the initial V-80 design variants:
