Axial's new Walker Evans beadlock wheels come with plastic SLW hubs that mate directly to the thru-pins on the axles. That setup is okay to start with, but it works much better if you install the Axial 12mm hexes on the axles (stock on the Wraith, but you have to buy them separately for the new Yeti), and then put these aluminum SLW hubs on the wheels. Zero wobble, no stripping or slipping, nice and solid. However, you do need to make sure to tighten the wheel nuts properly, and the little 4-in-1 wrenches that come with most RCs won't be good enough. Use a proper socket wrench to make sure the wheel nuts are tight enough, otherwise they'll back-out every single run, because the wheel nuts can't bite into these aluminum SLW hubs the same way they could bite into the stock plastic hubs.
