I don't disagree with your comments, Nick, but do think that much of what you propose could be equally well done with conventional controls. Surely one of the big drivers for FBW, in general, is also damage tolerance and weight reduction (which you suggest is slight for a helicopter), and this is why, thus far, it is only really seen in military designs?
On a similar theme (modern avionics) though slightly off topic; one thing that I find odd, given the progressive nature of the Sikorsky team, is the choice of display symbology for IAS, ALT and Rad-Alt for the 92 i.e. small round gauges. I agree they may be more intuitive for a pilot used to conventional instruments, but I feel they miss the opportunity to deliver the greater situational awareness that tape displays can offer. That initial extra hump in the learning curve during the transition, that may be experienced, is more than offset by the subsequent benefits (I humbly suggest).
