The roy focker is obviously revised since the rick version. Some of the paints used inside the cockpit is not as nice. Rick edition has more of a gunmetal look than just flat black paint. And the weathering is nicer on the rick edition. Different shade of paint on the rick console as well.
The cockpit hinge for roy has been remolded to be a little thicker in some areas.
Very few lights differ in color as well.
