I flew one last week where the governor switch was recessed right back inside the end of the collective lever. In fact, when the time came to switch it on I could not find the thing at first and had to bend forward and look at the end of the lever to see if there was one there. It was the normal small toggle switch, but recessed in so that only the very tip of it protruded past the end of the lever.
I don't know if this is a modification, but I have not seen it before on any of the other R22s that I have flown.
Incidentally, I think that in the POH it says that flight with the governor off is prohibited except for training. So that should put people off practising it.
