The Enstrom 480 and 480B turbines will carry 4 (5 at a pinch).
IMO excellent helicopters - especially the latest 'B's - and in a different class to the R44 - smooth, quiet, spacious and very well engineered.
But, 480s will start nearer £200k+ and 480Bs will be £300k ++. Running costs are likely to be higher than the R44 (TT straps every 2 yrs), although Jet A is half the price and depreciation would be less.
