My neighbor and his son says the Futaba Receiver Capacitor(item # FUTL6500) will do the same job as the KO Propo Advantage Capacitor A(item # 45558).

I believe the KO Propo Capacitor it built for the ESC and it can take more power loads.

But; I'll take the advice(info) from you pros.

Thanks

Hi. Have a look at this video. It may help you. The guy is regarded as a bit of a genius over here

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.

They can prevent excessive heat but can't get rid of it.

The rate of discharge and charge is also important when picking a cap for the ESC.

-Installing a Capacitor to the ESC or Receiver isn't specific to the one electronic equipment. . .(?)
-The wires from the ESC or Receiver to the Capacitor have to be short.

...am I missing something?

(some of the electronic stuff is like magic tricks to me...Ha Ha!)

I should add, you can always add one to both sides. Wire length wont play to much of a role in this. Its not like your going to setup your cap 2 feet away.

A capacitor on the battery side, helps smooth out voltage input to the ESC.

Adding a capacitor to the Rx helps with any voltage spikes from a servo over working the BEC. This is why people install glitch busters with Savox servos. Savox's are power hungry and most built in BECs are not built to handle the loads. This is not true in every circumstance but its a good rule of thumb. Alternatively installing a high quality BEC will usually solve most glitches stemming from a servo.

Thanks again for the info; Darkgenerals.

It looks like my neighbors are partially correct about the Capacitors.

And the parameter that is most important in this regard is "ESR" - equivalent series resistance:

Whether this matters in an RC application can be debated, but it's a major issue in 1:1 automobiles that have to operate properly at low temperatures and with strict requirements on EMC.

If you think this is snake oil, you should check out the stuff acuvance is selling. They have about 10 different capacitor options, including something called "photonic stabilizer".

for those interested

Wow, some of the things they sell are pretty amazing. Thankfully they are obscure products, and hopefully very few are sold.

Thanks for the info.

I didn't know there is such a product.
