RE: foam tires wearing unevenly
Nope, he got the regular version, no biggy, it'll prolly keep us busy in the workshop for a while.
If you wanna make those rears last longer, try slowing down. Don't enter a corner so fast. Start by trying to make the shortest "line" through the track, and then gradually pick up speed. It sounds, and will feel kinda silly at first. But after doing that for a day, and really learning where you can push it and get away with it, I promise you'll pick up a second or two. Sounds funny, but sometimes slower is faster. I used to beat a bunch of guys with my old RS4 Racer 2, with and HPI 15 fe, slow as H*^##, but I was able to hang it through the curves, in wich they would over shoot. They would overtake me on the straightway, but they had to catch up first...
Focus on not letting your traction go, and once you get it dialed in, it'll feel like it's on rails.
