The two versions with two seats display 2 pilots.
The two versions with one seat, only display 1 pilot.
All four versions show a weight available for co-pilot, but this is probably ok even for the 1 seat version, as there is a floor mounted jump seat modeled and could hold a person, gear, a large rubber duck for ham or sumtin’ else.
