The Hughes 269C has a left PIC seat - something to do with Hughes saying that only poofs and perverts sit on the right.
Having done both left and right hand seat, I'd say that right hand seat is easier in order to have access to the instruments/radio.
When sitting in the left seat and wanting to change radio fequency, I would have to hold the cyclic in my left hand which results in some very inelegant flying!
