A good wattmeter is the most valuable tool to have for measuring performance in an electric power system. When installed in line between the battery and ESC, a wattmeter allows you to see how much current your motor is pulling, and how much power is being produced. It also allows you to do a quick check after changing to a different size prop to make sure that you are not exceeding the current ratings of your Motor or ESC.
