In most Hollywood post production studios the sound libraries they have access to and probably the first helicopter sound bytes returned by the software query (startup, inside, outside, turn-off, etc) come from a trusty JetBanger, except when it dives in which case it sounds like a Stuka.

Back to topic. I'm not an operator just a user.
R44: If your tall and don't have little short feet your right foot will be angled inwards which becomes uncomfortable. T-bar cyclic is hard to love.
BIII: If your tall your head may touch the overhead, also high skids are nicer. Front seat is crap but can be replaced with aftermarket ones. Not sure if install/removing pax side pedals still needs to be performed by licensed engineer.

Prefer the BIII anytime money isn't an issue, unfortunately most pax think they are much the same thing.

Yes, and is usually shot down or crashes;)

Buy the optional pedals where the pilot can disconnect two small levers and turn them into a footrest for the pax, without removing or interfering with the control runs.
