I was able to get to the track early enough to really tinker with the XXXcr tonight. As I had stated earlier, I have been running the B4 until recently and I have done nothing but push since I got the Losi. The Amezcua set up was much closer than the Robbers set up on my track, but I still found myself jamming the brake in many of the corners to get it to turn in. I finally gave up on most of the set up info from all of the Losi setups and went a different route. I know that the B4 turns so I did alot of measuring and figuring and came up with a setup that would be similar to a B4 setup. It is not a typical Losi setup, but it works! I can finally get around the track without that "lap time killing" brake!!

I promise you that the rear shocks are gonna look funny on the car, but it really does work.
