To be fully honest. What is fastest class at your track? I strongly believe it is one of the 1/12 classes. At TQ there is hardly any TC faster than 1/12 17.5 1S.
I don't see the need to change to 2S in 1/12. I can't believe that a 30$ voltage booster is scaring off potential 1/12 racers.
BTW 1/8 electric is using different speedos and 4S batteries and no one is talking about this.
