I have now discovered that Rotorway have a new helicopter the A600 Talon.
This has a dual fadec system, a shaft drive tail rotor drive and a cogged belt main rotor drive that appears to address the weaknesses that other people have highlighted.
It is also built to certified a/c standards which should mean that the possibility of FTO's using the machine might someday be possible.
