As for the plug thing, I too was thinking about that. Just makes things more versatile. The only problem is that the plugs degrade over time. I know that I change mine often on my escs and motors. I don't like the idea of having to bend them to make them tight either.
I hope that my Quark gets here in the next week, if they fix it. The way my luck has been going, they might tell me that it's not covered for whatever reason. But...if I do get it back, I think I'm going to make a bank that will fit as many caps as I can within a length equal to that of the Quark. Then I can just epoxy the Quark to the cap bank and then epoxy that to the heatsink.
The epoxy is easy. The aluminum oxide powder can be found at hobby shops catering to rock collectors. They use the stuff to tumble polish rocks (go figure). Get the finest powder that you can. It costs around $8 for a 1lb bottle. I just mix up my two part epoxy and then add the powder until the epoxy turns into a paste that looks like thermal epoxy. They you just apply it as you would the epoxy. Once the epoxy starts to heat up, it flows really well and gets into all of the nooks and crannies. I won't say that it works as well as Arctic Alumina, but it does work well. It does move heat.
I do have to say that all of this leads me to some wondering. Actually, I'm starting to think that I'm full of it and all of my positive results have been figments of my imagination. I mean...if adding caps is all it takes to make things run so much better, why aren't the manufacturers doing it? I'd gladly go for an esc that runs cooler at the sacrifice of some space. Of course, I suppose I just have to keep in mind that we are running these escs out of spec; but hey, my MM got hot when I ran it in my T4 too.

I must have missed this post? :eek:
No troubles AAngel, please I don't want to be out of your way over the caps, do it whenever you can. As I don't have my Quark back yet anyways.
I don't even know where I can even get alum. oxide powder here, or for that matter a store that sells that stuff. I'll keep my eyes open.
The results you have seem real to me, if those are the temps you read... Like you said, the reason manufacturers don't use more, is space. We really just nee higher 'performace' caps, with lower ESR, and higher ripple current capability.
BTW, I though the MM had 220uF caps? I see in the pic they are three 330uF caps, that might be why the MM doesn't have as bad cap issues as the Quark.
