Watts in an electric motor is like HP in a nitro motor, and torque (in Newton millimetres) is what it is (obviously, the higher the number in both, the better). You also want to see how many amps the motor is pulling. 12-13 amps at around 3 volts are good numbers in a stock motor, as for mod, not sure, have to ask some of the mod racers on this board. (you gotta tell 'em what wind it is, too)
