In the instance of a capacitor for either a ESC or a glitch buster, all your doing is smoothing out any voltage dips or spikes in power.

Your neighbor is correct in the sense that both the Futaba and the KO will do the same job. I couldn't find any of the uF or voltage info on the KO but it looks to be a couple of 16v 550uF caps in parallel. Which is pretty close specs to the Futaba.

I would really suggest looking up how a capacitor works for a better understanding but capacitors are built to handle a voltage range. So the Futaba ones are 16v, so it can handle anything from 0 to 16v, and I'm sure the KO is the same. With out some pictures of KO's bank naked, I cant be 100% sure its not 16v but just guessing, its doesn't appear to be built to take any more power.

How a Cap works You can even save your self some money and build a cap bank that does the same job, It even allows you to pick up nicer caps, but not like it matters for something this.



"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." - From KOPROPO.com

Holly hell, I'm glad I dont buy KoPropo' products. This is snake oil sales man stuff. I would love to see some proof that a capacitor helps the motor run cooler.
