SFIM - Oh no you can't. Learn in a Robbie and then get into an Enstrom and see what sort of a balls up you make of throttle control until you get the hang of it. It took me a significant chunk of the 5 hours of conversion training to get it right. (Maybe I am just slow). I have no doubt that someone will disagree, but if you master the Enstrom, that sets you up for most piston types, better than the R22. I have a vague memory that the CAA consider Enstrom, Brantly and a couple of others as one type for renewing type ratings.
I have no experience of turbines and learned in a R22.
