It may be that by design that Robbies are less tolerant to turbulence thaN the other 2-blade helicopters mentioned, but all can experience mast bumping. I think singling out the helicopter and not the more relevant factors in these accidents is the wrong focus. People just need to be more aware of the limitations of the aircraft. And particularly of their own.
