This capacitor stores power from the BEC and acts like a filter to eliminate noise and static that can cause glitching between the transmitter and receiver. It also boasts the benefit of reducing the load on the ESC’s BEC. It will also stabilize power delivery due to momentary voltage drops such as sudden throttle application in an electric powered RC vehicle. It comes pre-wired with a Futaba J-plug, ready to plug into any open channel on the receiver.
