The fast (pro) guys have even moved back to brushed 19T vs the brushless b/c they are getting more power out of them. Brushless winds up faster but when you dont need to do that a lot then you are slower.
Wow, that's impressive. I think we maxed them out between 28.5 and 31 on carpet on-road without many long straights.
In a straight line, the 19T should be faster, so it makes sense on a track like that why guys would go with 19T.
I can't imagine what you'd gear your 13.5's at on a track like that. I get them up around 43 on a tight course.
