Knowing all the vectors and forces involved in changing attitudes in aircraft is nice to know stuff.
However .....
Knowing how to make a given aircraft be it fixed or rotary wing do exactly what you want it to do smoothly and efficiently can only be learned by actually observing and doing...it is learned far easier and faster if you have a good teacher.
If we get to focused on how a given aircraft behaves during a given control input by visualizing the forces at work we tend to lose the real picture...which once again can only be learned from doing.
For instance if you are flying in close proximity to the ground in activities such as aerial application, aerial fire suppression, air display flying etc. believe me you will not be using the flight instruments to fly the desired attitudes.
Good discussion Dudley.
