Hi, was just trying to learn a little about how the gearing works. Right now stock i believe it has the 86t spur and 28t pinion. 80% of the time i run on pavement, occasional dirt track here and there. I have a 3s lipo, 2s lipo and two 3000mah nimh batteries. Is there a better combo of gears for just overall speed or is should i stick with whats in there. Also i don't want to have to worry about watching temps.
