I can pretty much agree with what's said here. Sometimes on a long flight in R22 ( don't laugh ) I would use left hand on cyclic for a minute or so in the cruise when my arm got sore holding the cyclic after a couple of hours. That's the most I've tried it solo.
But a few years ago I was having a lesson in the left hand seat of an R44 Raven with the instructor on the right and he asked me if I would like to try swapping hands on controls. So carefully ( with him on the controls I might add)
I swapped hands , so left hand on cyclic and right hand on collective in the middle of aircraft I had a shot so to speak.
The result basically as Shy had said, You have control was my quick response, reminded me of what it was like learning to hover all over again.
Would I try it on my own . No Chance.
