Crius

I did one of these Abrams a couple years ago and kind of went all out on it, with metal suspension, road wheels with rubber tires, metal tracks with rubber pads, three colored camouflage paint job, special effect to get the armored glass on all of the periscopes, decals and markings for the tank Battalion that was across the street from me when I was in the Army in Germany, extra bracing on the inside, and henntek idler, and on and on and on.
There used to be video of it here in the classified section, but one of the software changes wiped all that stuff out. If you think they might be of help to you, they're at my YouTube channel. I might be able to dig them up and post a link.
