Thanks guys. The boys are pretty excited. The Vader car is the one that I had to slow down a little. This should be a good race. Most of the boys and dads came over for a work shop, so blocks are drilled correctly and most designs are good. I know that a few of the dads stepped up and bought some good stuff from John. They will be going up against some 1.7 cheetah's so who knows. The wheels on my boys are 2 grams just in case they wanted to send it up to the league race.
