Well Mr. Coyote.
I understnad your concern...but I assure you that I do know about the law of conservation of angular momentum and all that.
In just did not think it would have that much effect. The man pressure drops by 3-4inches, and I figured it might be some of that "magic" you are talking about having a go as well.
As we all know, the aerodynamics of helicopters is a bit more complex than the flaps of a 747. I find this topic very interesting and fascinating, and strive to learn as much as possible.
I apologize for frasing the question so bad that it could be understood the way you did.
I, however, do stand by the fact that there is no stupid questions..only stupid answers. If you are a CFI, I am sure glad I am not your student!
Fly safe
Ken
