John,
There is indeed a problem if people learn to fly a helicopter with a governor, and never practise flying without one. Having had an expensive overspeed incident myself, I then did several hours training in the R22 with the governor switched off, and I now monitor the RPM constantly - just as well, last time I flew I switched the damn thing off with my sleeve three times!!!!
They should do something about that switch - but that's another story. Anyway, I think everyone should do a fair amount of governor-off training.
However, your doubts about learning anything in an R22 that can be carried through to other types??? What exactly do you mean? I learned on the R22; I've flown other types, though not a huge amount yet. But if there were any major problems, neither I nor any of the instructors have noticed them.
I've read your post several times, and I'm really not sure exactly what you're getting at.
