The T-55 generally is good mechanically, and as you noted less than desirable modeling wise.

It makes a good runner with surprisingly good tracking on all surfaces including grass.

The inside can get cramped as the profile is lower than the Pershing making electronics and wires sticking up a problem compounded with the elevation that uses some of the inner hull for max elevation.

I conserved space by installing an i-pod speaker in the extra fuel drum so as not to have to have a speaker box inside, and I was still able to install a slip-ring for 360+ turret rotation.
