Look at Kamov HB-XKE, it has a huge bubble window on the left side. Below it, they have a little instrument panel for TQ and so on. They fly VR AND use the mirrors. Whatever works best in that particular moment.
seems to me as the same i wrote on the first part of this thread.
To have mirrors doesn't mean to forget VR. The pilot could use both methods and choose the best in one moment.
... There are not so much helicopters with side instruments....
A AS 350 to be flown from the left side is an optional kit (incl. 1 additional seatplace in front) from EC. The number of AS 350 with this kit is limited, mostly used by tour operators. But there is also a bubble door on the right side of the a/c available.
