The Tamiya CC-01 (Cross Country) chassis is a favorite vehicle amongst R/C enthusiasts. It’s easy to assemble and offers realistic cross country running. The list of body styles available has grown with the addition of the Unimog 425. The Unimog, of course, is a multi-purpose truck with unrivalled off-road performance and its name is an acronym which stands for the German description "UNIversal-MOtor-Gerat." The 425 variant was a heavier model that was produced in the 1970s and 1980s. It featured a 120hp engine and 2.81m wheelbase.

The Tamiya R/C replica faithfully captures all of the full size Unimog details down to the large snorkel and cap vent and large side view mirrors. The Unimog body is mounted on the capable CC-01 Cross Country chassis, which features independent front suspension and a rear 4-link rigid suspension set up for fun scale trail running enjoyment.
