All, I know is by August at the latest, we 12th scale racers down here In San Antonio will be up and running 13.5 and 1s LiPo for our stock class. Although by ROAR's definition it is not stock, but it will be close but not equivilant to 4 cell /17.5. We thought about 17.5/1s but for us here it would be to slow in the back straight-away.

Hey Yang, were are my tires????
