Yeah it is a roller. I would like to see an available rear wheel steering system. Did you see the wheel weights? Thats an awsome feature for a crawler.
It does look alot like the axial as far as parts. I figure they are hearing that a bit. I really would have steered clear of the green anodizing though lol. Doesn't look bad. Should have metal gears, I really doubt " glass filled nylon" will handle the strain very long. Honestly I hope the locking diffs work out but they sound like something that would fail relatively quickly, we will wait and see I guess.
