SAS has been a factory option on the R44 since August 2015.
I had heard rumours that a heavy version of the R66 was in the works with a three blade rotor system and a great hook-load capacity...
I wouldn't be surprised if a 3-bladed version appeared but it would need some significant structural reworking.
There is a new Diesel engine in the 300hp range on the horizon in the next year or so from one of the big US engine companies so I wouldn't be surprised if the R44 Delta makes an appearance with three blades, turbo-diesel power and a price between the Raven 2 and the 66.
All exciting stuff. Thank goodness for some competition at last.
