I flew this auto pilot in a Bell 407 with G1000, back in April, and it reminded me of the Honeywell auto pilot in the G1000 fixed wing aircraft prior to the Garmin auto pilot/flight director. It controls the aircraft reasonably well, but is barely integrated.
If Garmin develops a FD/AP for the 407 G1000 installation, similar to their fixed wing auto pilot/flight director available in the Mustang/Caravan and other single engine aircraft, the HeliSAS will become a distant memory, just as the Chelton EFIS system has mostly become with the availability of G500H and G1000 in rotorcraft.
