The KO Propo 45558 Advantage Capacitor is a compact upgrade that helps stabilise the power feed to your electronic speed control. By damping voltage spikes and cutting electrical noise, it promotes steadier throttle control and reduces the chance of transient damage to sensitive components during hard acceleration or heavy loads.
Built with RC use in mind, the KO Propo 45558 minimises fluctuations under load so motor and ESC responses remain consistent. That steadier voltage helps reduce glitches and improves controllability on the track or during practice sessions.
Fitting the capacitor is straightforward for anyone comfortable with basic soldering or connector swaps, and it suits a broad range of ESCs. Once fitted, many users notice crisper throttle feel and potentially reduced strain on electronic parts.
