I guess this have a other reason GG, when the Heli gets out of control, and he is upside down in low altitute, there is the ejecting seat useless.
But better you have one then no eject seat. For example you get hit by a stinger or igla in the tail section, where the tail-rotor is for the standart heli`s and you get a 360 spin, then good night especialy in a rough landscape like mountain`s. You will crash and burn.
I guess this eject feature is not so bad.
