I kinda like my motors around .27 for my touring car. I feel thats when they're the fastest with a good amount of torque. But in my 12th scale, the smaller the better
! Because you don't need any torque in 12th scale really, and so the smaller comm just gives you more rpm, but at a slight loss in torque.
