TheiC: There are a number of PPRuNers with the numerals '500' in their username (and which can get a little confusing at times) but .. though I don't know him personally PPRuNer
Hughes500 seems to have a background of involvement with 500's in the UK so it could be worth dropping him a PM as he may be able to point you in the right direction.
Herewith .. a couple of UK registered 500's, a 'C' and an 'E':
Note: The 500 is a little louder (inside) than the 206 and .. the controls are not hydraulically boosted .. so the craft has quite a different 'feel' and there is a 'technique' involving the use of a cyclic-mounted trim switch 'coolie hat' which one has to learn (not difficult).
To appreciate the 500 you need to try out some slope landings and hovering manoeuvers .. this is where you will see her crisp responsiveness shine through. In the cruise (if well tracked) the craft is wonderfully stable and responds with alacrity to any inputs but, when trimmed in the cruise, the cyclic tends to display a little bit of movement (feedback perhaps from the lack of boost) which can cause the 'stick' to shake when holding it loosely. Nothing to be concerned about .. just little quirks of the aircraft.
What I'm saying is .. you will probably find one or two traits which at first may seem peculiar but .. after just a little while these are easily embraced and give way to an appreciation for the craft's stunning responsiveness through that five-bladed fully-articulated rotor. However, I think it will take more than an hour to 'embrace' the 500 because some of these traits can initially be off-putting .. indeed they were for me in the very beginning until I got to see just what the 500 could do!
