About fifteen years ago I had my first flight in an R-22 when I was asked to help set up a flight training school using same.
I did not feel it was a good / suitable type for a training aircraft for a number of reasons and I have since read that Robinson himself stated that it was never envisaged to be used as such.
End of story. I have not flown in one since.
Just my opinion.
