HeliComparator,
"Steady - you're getting a bit technical here for us mortal pilots."
Hehehe, sorry 'bout dat. I live in awe of you folks who not only routinely fly these amazing machine, but somehow manage to make 'em pay! I have to join the computer dots, and simulate dynamics for my dinner.
"Better stop now 'cause you can tell I barely know what I am talking about!"
Hehehe, the answers are much appreciated and well noted. I will read up on the EH101 active mounting system. In automotive applications Lotus did some work on predictive algorithms for sound/vibration absorption. I'll have a root around for some info on this, but the acc position would be less critical.
I am singularly impressed with heli pilots, since they always seem to have a good understanding of the mechanics of their flying machine. I think you have demonstated this point nicely...
