That’s not my experience as a helicopter pilot.
I believe the textbooks say they are “statically stable and dynamically unstable”, but the bottom line is you surely do need a control loop.
I've never even been in a real helicopter unfortunately. I really wish I could touch the stick of one once to see how it compares to models in terms of touchiness... it's (un)fortunate that there's probably no realistic way to try that.
