Have'n built that one, but I've just completed the Tamiya 1/16 King Tiger ll (static display version) and am impressed.
The fit is typical Tamiya - everything fits perfectly and there's no "tweaking" of anything needed. The only real mods I made are are cleaning up of mold likes (the mold lines on the tow cables are a real pain) and filling the screw holes in the side skirts once they were glued on.
The handles on the hatches are molded solid, so I cut them off and replaced them with brass wire.
All in all, I found the level of detail comparable to a good 1/35 scale kit - not nearly as detailed as I would have expected - maybe because the thing needs to be a little more "robust" than your average kit because of the R/C needs.
In all, it's got perfect fit, easy to assemble, and looks very impressive. I think it was worth the money paid.
Cheers,
