Over the course of the past few months I have come to like the Auto World X Traction chassis. Initially I was not impressed with the chassis out of the box. But then I remembered that Christmas in the early 60's when we got our Thunder Jet racing set. All Christmas day we worked to make those cars go around that track. I was fortunate as a kid to have a Dad that was mechanically and electrically inclined. By the end of the day we had those cars running pretty good. That said, I thought I would try the basics to improve the performance of the X Traction... and you know they actually run pretty good!
