Just recently did a turbine rating in Kiwiland.
Whilst the FH1100 was no more difficult to handle than any of the (only 3) piston types I have trained on, I found the power management part to be easier.
BTW the FH1100 has pretty impressive hige and hoge figures compared to most comparable a/c, and at one stage I was autorotating at 80% RRPM (as instructed) which I found interesting, especially remembering the initial 20 hrs training in a robbie and other less forgiving ("ROTOR RPM!!!, ROTOR RPM!!!) helicopters.

There's some good stats and some really interesting history on the FH1100, and the other two contenders for the [light observation helicopter platform] contract in the mid- sixties which also bought us the original military prototypes of the B206 and H500.
