Quark fried, blown capacitor...

[zeropointbug]

AAngel: You bet, you can cut a little insulation from each lead and stick each cap lead into the wire strands and solder that. That's the only way I can think of at the moment? And yes, those on eBay that i linked, they will work very well, they are very low-esr caps. Kinda nice if one could find a better supplier, so you wouldn't have to buy 200 caps when you only really need two!

I totally agree with you that an esc like this cost, and performance should be better able to handle these vehicles. But the reason they can't put larger caps on it, is simple, space. They should make a little kit, or a "Quark" aftermarket cap they can sell if you are using a large RC car. I would only benefit them, IMO. The other reason this esc fails, is the heatspreader problem, if they fixed that, it would be 100% better.

The smt caps are useless for this, just try making a connection with those little tabs on them! :024: Most smt caps are solid polymer caps, which at the lower voltages (<16v) they have really good esr ratings, and they are very durable. Motherboard manufacturers are using them lots now, video cards have used them for about 5 years now. Nothing that will work for this app. though, the low-esr electrolytic outperforms them at these voltages, or at least what I have seen.
