Australia hasn't had TCS for years and years. And THAT is why we went to the Hobbywing 13T brushless system.
And I doubt you'd find a single person who doesn't think it's the best decision we ever made! Silver Cans and/or Sport Tuneds - up to 2000 rpm variance between what are supposedly the same motors.
Hobbywing, about 150 rpm variance.'
I can understand people staying with Silver Cans if TCS rules predominate, but if they don't then I couldn't change quickly enough!
