Well, I just tried the MMDesign with experimental bladeslap. And it seems to be the same.
But the bladeslap seem to be disappear sometimes at random, probably like in your mod too.
it would be really cool, if bladeslap could be toned down like 50% (in cockpit) and happen more consistantly to what the helo is doing.
Edit:
Oh, and is it possible to add some audible feedback for switching the overhead panel switches?
