There is nothing better that the Jammin series. I have been racing my x1-cr fte for 3 seasons, and only replaced 1 arm, servo saver top plate, and the shock seals.
I just recently picked up a crt from ebay, put $50 into it, threw in a new motor, and took it to the track and pulled a #2 my first time driving it. I'll tell you right now, I am not that good of a driver, but I can get wins because neither of my cars have ever let me down.
