I did my initial training on the UH-12ET (the turbine version), and engine off to the ground where the order of the day. Great strudy machine, loads of inertia and wide skids!
I couple of years later, I found myself flying an R-22. Nothing to do with the UH-12ET, but once I got use to it, I enjoyed flying it.
Anyway, at the end of the day, if I had to take my family with me on one of these to choppers, I'd certainly go for the UH-12.
I know little about spare parts / service availability for the UH-12 wherever you are. I guess that that could be the only inconvenient, if any.
