Whenever voltage dips and peaks are a problem, this capacitor with 2200uF/10V is the solution. It improves the voltage stability of the receiver and prevents short-term voltage drops that can be caused, for example, by peak loads from high-quality servos. The stored energy is used to bridge such drops. With reverse currents from servos, however, so-called voltage peaks can sometimes occur. The capacitor can filter out and cushion these high-frequency signals just as easily.

The capacitor is plugged into a free receiver slot.
