The R4 was created in response to complaints that the R2 was too expensive and the R3 was too suited for military use. The R4 became very popular in the outer rim territories because it came pre programmed with detailed information on many general purpose craft like air- and land-speeders, and specalized in repair work on such vehicles.
The R4 is more likely to be found in a garage than on starships because it can only hold a single set of hyperspace coordinates.
The R4 features a head cupola that begins round at the bottom an rises steeply to form a small octagon at the top.
