At the end of the day, i think if Kamov intended to produce the KA50 with some sort of effective flight governor their budget would have been dramatically increased if not blown out. And for what really, a good pilot knows the limitations of his/her aircraft. How many KA50's have crashed due to rotors colliding while flying within safe flight parameters specified by Kamov?
It's great we have computers that can do 50 million calculations a second but sometimes it's best just to use the good old brain, where you can have a solution with 4 calculations. ;)
