Nick,
Thank you.
Lu,
Clearly you have taught yourself lots of things about helicopters and good luck to you. Unfortunately, many of your empirically derived theories are not shared by those with far greater research facilities and technologies available to them. I have considerable experience as a helo maintenance test pilot, covering Bell products predominantly with a lot of others thrown in. I have read your prolific writings and am impressed by your zeal - unfortunately your dogged desire to be right all of the time has made a different impression.
Bell does not hold all the cards on heicopter dynamics - there is a rich academic and research literature out there. Please be careful to distinguish what is mere surmise from what is scientifically robust research - there are a lot of young folks out there who may believe your version of events, merely because they have yet to be exposed to better information.
