To give you an idea of the available intertia at the bottom in a Bell 47 EOL, I was recently told by an ex AAC instructor that the 'show-off' exercise to give students an idea of how much they had to play with, was:
EOL to a marked spot, lift off turn 90 degrees, move three yards, put her down again, lift off, turn, etc. with the challenge to complete all four corners of the square.
Not many made the fourth, but it was possible!
I'm sure this isn't a myth, as another AAC instructor told me the same story.
All very impressive, but with hydraulics engine driven (not off the transmission), there's no such thing as a practice for real....
