The car is extremely free right out of the box. It took me a couple of months to get my FTTC3 to free up. I didn't have to do anything to the XRAY.
I race mine in stock and it is extremely competitive. If anything it is a lot more efficent then the majority of the cars I race. It is only going to get better as well. Plus it is box stock, no option parts on it yet.
