zxt: I prefer the rs4 sport for racing instead of the tamiya ta03.
All: With all the talk about tub, FRP and graphite having more or less flex, I would like to know how do you guys determine if the tub, FRP and graphite has how much flex? Is it measurable? Only when we can get some actual measured data we can make a conclusion decision. After that, we'll have to determine if flex is good or not. Anyone?
