All you have to do is amend FAR 27/29 / CS 27/29 to require manufacturers to provide comprehensive information about how their helicopters behave, and a zero cost data package available to anyone with a need to know. Simples! And if it's in the regulations, it's a level playing field. Anyone who was actually interested in Flight Safety would support this. Trouble is, too many people involved in such things are more interested in the politics and their personal careers, with flight safety coming well down their list of priorities.
