From what I understand, brushless achieves power equal to brushed in a smaller motor. Also brushless experiences little acceleration loss when going to a bigger prop or a higher pitch. Brushed has a major trade off and the more it has to turn or the higher the rpm, the longer it takes to achieve it. I gather this is what gear boxes are for in planes: to increase prop rpm on a higher turn motor. Furthermore, brushed has brushes a source of friction, which means heat and eventual loss of brush usage. Brushed, from what I know, is only inrunner, and unless you brushed can be removed, it won't be easy changing them. Due to the fact they are inrunners, I believe inrunners have less torque than out runners.
