I can't speak to the Pyro since I don't fly it, but in general, all helos are like that - except, maybe, for a few of the bigger, more modern ones that have some form of stability assist. Those are the exception, not the rule. Helos are inherently unstable and the pilot's job is to balance all the forces, and the way they change in different phases of flight. Feels like balancing a plate on a stick. It's not everybody's cup of tea. I spent a year flying almost nothing else in FSX and X-Plane and learned a lot, and became a better pilot, but eventually moved on to other things.
If you want to get a good overview of helo flying, Hovercontrol is a great site - well worth a look.
Hope this helps.
