Enstrom P1 on the left as the centre collective is removable to provide the middle seat. Can be flown P1 from the right but the start button is a long, long way away on the end of the left collective lever. With Enstrom lateral weight & balance is irrelevant. Its just down to practical limitations.
The pilot has to let go of the collective and hold the cyclic with the left hand while operating radio, mixture, etc with the right. Not a problem though. If the engine stops whilst messing with the mixture, the juggling to try an in flight restart is awesome. I know. it happened to me.
