Why a brushless motor? Unlike a brushed motor, brushless motors have no carbon brushes contacting the armature of the motor. This means there's less drag in the moving parts. It also means there's less friction surfaces to wear out and needing to be replaced, less electrical noise and no sparking. These advantages are all very nice, but for RC cars, the real benefits are:

• Much higher motor speed. The maximum speed of a brushed motor is restricted.
• Easier to cool as there are no electromagnets on the stator
• More efficient, so your battery pack lasts longer

For those who like to stay on the tarmac, this is the ideal introduction to RC cars.
