I usually like the Unimog scale rigs, but I'm not into this one at all. For one thing, the Unimog body doesn't look very scale, and it has the appearance of a toy rather than finding it hard to tell if it's an RC or a fullsize rig on really big rocks.
Candyman, the center of gravity is definitely off, but it's for a reason. Tamiya builds their RC's to be scale, and they aren't build to perform. They're basically built to look good, just like most of Tamiya's kits. To get the CR-01 rover to crawl decent, you pretty much have to completely redo the entire suspension configuration. That's why things like COG and other things that make a rig comp capable aren't paid attention to by Tamiya, they are focused on building rigs that look scale first, and performance is further down the list.
