Quark fried, blown capacitor... - RC-Monster Forums

cemetary gates: They should work alright, if they are Low-esr, but I don't know of any, if any low-esr caps that have a running temp of only 85c. The more caps you add, the lower the operating temp they will have, as long as they are low-esr type.

BliPoRaceR: That is the ideal way to mount caps yes, but like AAngel said, it's too exposed for my tastes. The way AAngel mounted his caps on his MM, and Quark is more what I like, and the resistance from adding that little bit of wire is minimal. But you sure would want to keep the caps on the pcb (stock).

Looks like it would work very well though.

AAngel: If you do the mod, you won't likely be able to take it off the FET's again, maybe the case though. I am going to get a FET clamp machined first for now, until I get the case machined (and finalized). I'll use one of the heat sinks I have and mount it to it.

Oh, yeah, I don't think those are low-esr caps. If I were you, I would not install them, they will most likely blow out and spill electrolyte all over your esc, and possibly damage it as well. sorry.

You can freeze the ESC to make the epoxy brittle enough to pop off. I usually put the whole ESC in the freezer for about 20 minutes and then gently twist and/or gently pry the sink off. However, there is a real chance that you could damage FETs doing this, so do it at your own risk. I've done this to two Quarks and one MM with no issues whatsoever.

But really, why would you take it off once you do it?

Oh right, you did say you did that. That's nice to know then, I was just thinking if he ever wanted a case machined?
