KO Propo have introduced the Advantage Capacitor C for an ESC for a brushless motor. This capacitor suppresses the decline of power in the latter half of a running time, allowing improved average lap in race and leading to a shortening of total time. The characteristic of this capacitor suppresses excessive rise of torque for a modified motor. To ensure that you can use the Advantage Capacitor C, please check the “Capacitor for Brush-less motor Chart” here.
