brushless motors seem to have more punch than its brushed equivelent but the brushed seem to eek it out on top speed when it is built right.brushless is cool because they are always fast and there is no voodoo behind it.it is just fast.the down side to brushless is that they are not as easy to drive as a brushed motor.i still run my 5800 and 4.5 brushless motor in my sedan because of lack of maintanence.i usually run better lap times with a brushed motor though.it could be just me though.
