The infamous Mi-48 "Kajman" does not exist in real life . Its a mixture of a Mi-28 Mi-24 and Ka-50 which might exist but only if two Russian factories will collapse in one . They dont like each other alot and probably will never create anything like that . They are sort of at holy war with each other trying to make one of two different helicopter systems main in russian army. But I would definately fly in that amazing mixture of helicopters with huge pleasure . Specially if it will act like it should =]
