Glad you lept back in Lu.
You have accurately described the situation in your post. We have said all along that centrifugal is essentially a tool to easily explain what is going on when talking about another complex subject. In Nick's case, that was blade lag, so he used centrifugal because it simplified the explanation of blade lag. He even put a joke in there for those who know centripetal is real & centrifugal is not.
Same same with gyroscopic precession. Easy to explain and use as a tool for day 1 knowledge, but not what is really going on.....but lets NOT go there again!! <img src="eek.gif" border="0"> <img src="eek.gif" border="0">
