I don't think hes lying, but I also don't think this is a magical formula that will transform 1/12 scale racing. I think that his potential advantage in the corners is more a result of a longer chassis with more weight on the nose that can be setup and driven with more aggression than a tiny change in the rotational moment on any axis. I guess if your going to make a chassis that can fit the battery between the servo and rear pivot, why not face it sideways?
