Basically box set-up just changed diff oil and 20k-7k and shock 30-r 35-f yellow rear-blue front. Never drove it yet just a couple of laps around the basement. Oh, Havoc pro with 4.5 550 and a turnigy stick ack 6000mah 65c-120c when I weighed it battery centered front to rear. The scales where Amazon specials $7 to the door each thats $28 for all four. They all are the same I weighed a bottle open 26.4g on each scale so they all seem to be the same. just went up to $7 each http://www.amazon.com/gp/product/B0078JEIKO
