Re: Theory of a rotary take off?
My flight instuctor explained it very simply -
"Use the cyclic to control yer position over the ground"
"Use the collective to control yer altitude above the ground."
"Use the pedals to control yer heading"
"Use the throttle to keep the little needles in the green arc"
"Do not use them in such a way as to make me spill my coffee!!!"
(He also got upset if, on the first flight of the day, he lost his place in his newspaper.)
This has worked for me for 28 years.
Happy New Year to you all.
