I've been eyeing these up as well! They are a little wider, only by 10mm, but that's 5mm per side, which is only .1967". The brake drum casting/drive hex is what makes them wider, but on all the Tamiya rigs I have seen, the difference isn't noticable in the least. Dreamweaver's Classy Shack comes to mind. He's got a set under his truck, and they look really nice. All the major dimensions are identical to the Tamiya rig axles, except RC Channel's axles are a little thinner (cross section). 12mm vs. 15mm.

I never heard of anyone having gear problems. What failed exactly? If there is an gear upgrade set offered somewhere, I wouldn't mind finding that information out. Please share the link to that too.

I get a little closer everyday to buying a set of the RC Channel axles. I think they look a lot nicer, and they are metal, even if cast.
