Advantage Capacitor A (No.45558) was designed for non-boost brushless spec classes or brushless modified classes with very little turbo. During a race the heat build up in motor and ESC can cause a slower performance in the later half of the race. The effect of the capacitor can help in the suppression of the heat generated. Due to an effect of power-up of the throttle throughout the range, less throttle input is need and can result in lowering of temps and less voltage drop towards the end of a race. Get it here. For boost and turbo applications, we recommend the Advantage Capacitor B.
