Hi, my electro-skills are a bit dusty (or lacking ) so I'm looking for opinions of people smarter than me.
I read this article : http://www.instructables.com/id/How-...-buster-for-1/

I've had brown-outs with my new setup, and I happen to have 2 16v 10000uf capacitors ("nippon chemi-con", " 95NO2L - can't find any other info about it) lying around that I can solder a plug on (either on one, or put the 2 of them in parallel). That, plugged into my receiver, should work fine as a glitch-buster, right ?

Yes. Seems huge but if you can fit it, it will work fine! Good luck with the brown outs.

Yeah, they're huge but they're practically weightless on a short course truck and there's room to spare so I figured why buy an expensive small glitch-buster if these large things can easily be fitted for free

I hear ya! Let me know if it takes care of your issue!

yep that's exactly what spektrum does and sells for $6. The only "glitch" I see on that site is the explanation of what a capacitor does. There is no "noise filtering" going on in there. The capacitor stores energy...essentially a battery but with no cell memory.

The "glitches" from the car are when the mainly from power hungry servos that sucks all the power out of the RX, and your battery pack can't replenish it fast enough, therefore the RX shuts down temporarily.

Glitch buster works by storing power and act as a filter to remove any noises produced by servos. The advantage of using Glitch Buster is that it improves response time, which makes the servo faster, etc. The high capacity, super low resistance capacitor is used for Glitch buster.

They do not use HIGH capacity capacitors ..IF you use a High capacity cap you have the chance of Blowing thing up..its not like it store only a small amount and slowly discharges that energy its a all or nothing thing..6000uf is a small cap..a 20,000uf cap will cook ur stuff..they do not filter any noise.. you need a separate circuit to do that..
You either know your electronics or you should just not POST..your telling people things that will hurt them and their electronics..
Here is a noise filtering circuit..

Actually the capacitor does add a filtering effect, look at the signal with a frequency spectrum analyzer (aka FFT). There will be less noise over the frequency spectrum due to less and/or smaller spikes in voltage. The cap accomplishes this filtering by quickly storing and releasing small amounts of charge, and it is frequency dependent.

The cap does need to be in a circuit to act as a filter, yes, but it is in a circuit once plugged into the receiver. The circuit typically includes the BEC power source which has an output impedance (complex resistance) and the receiver & servo which have input impedances (same).

There are many types of filter circuits, one of the simplest is oddly enough a RC circuit, Resistance-Capacitance. Google will find this quite easily, one of many examples:
