Yes,
actually got hours on R22 and 44 IRL. Working on my ATPL(H), can fly everything rotary on sims, FSX Dodo, others + Helicopter Total realism (in FSX) and most of the pay (and free) helo addons for X-Plane (including Dreamfoil's R22, which is bitchier that its real counterpart...).
I have full size controls (costed me and arm and a leg but they're good http://www.komodosimulations.co.uk/) but still cannot keep the damn Huey steady, aiming weapons and firing is impossible, you might hit something eventually but you'll need to get darn close.
Yes the new flight model improved things a little, it went from UN-FLYABLE to almost humanley manageable but it is still FAR from reality, IMHO. Now, I've never flown a 205, but as said I regularly fly and R44 which would somewhat compare in size (although a little smaller) and has no stabilization and anything, is a teetering rotor (like the Huey) but no stabilizer (dampening) bar. Still I manage to HOVER and fly the darn R44 in UK winter weather... I would like to know the reason why I'm not able to fly the DCS Huey in the caucasian summer??
Was this tested with proper controls or would I be better off with, say an X52 or Warthog? Because if that's the case the Huey is a waste of money. A very nice toy, but that's it... a toy...
