Hi there, looks great, the tracks appear to be on backwards, the chevrons should point down the front idler, like a tractor tyre, that way they dig in, and are self clearing as the new mud, pushes the old mud out, the other way ther gather mud into the track, like a scoop, but thats a minor detail, i had the HE abrams, it was great in looks, but the rubber tracks really let it down, i always wondered if something could be done, and now my question has been answered in style, lucky you got skills in machining mould making and casting i think i would have to buy the metal track set from mato with drive cogs included, and use road wheels from pershing , but top marks for your skills, cheers,
