Oh for sure! My pleasure!

Yes, I am going to use the same clamp, as it's just thermal paste (not adhesive) on the FET clamp between the FETs, so you can transfer any Quark onto the setup as you wish.

Just for information, my ESC temps when running 7s2p geared a hair under 50mph (and big battery...) were I think never more than 10 degrees F over ambient, IIRC. You couldn't tell it had been running even, VERY nice. I could push the truck as hard as I wanted... and plus it seemed to have ran smoother, especially on startup, never cogged, ever. With my new Quark, it's annoying when I cogs, always at the wrong moment. Which only happens to me on 7s2p though, which was the same problem ppl have on 6s lipo.

Yeah, to be honest, yours should work just fine with even the most high end setups. What were the temps on that thing anyways? The only benefit my FET clamp has is the cap bank on the esc, which will make it that much more durable, although, overkill I might add, but none the less.

Do you have dimensions of these parts? It would be easier to find suitable copper piece. Is there thermal paste between copper and outer aluminum case, too? Or is it good enough with just copper against aluminum?

Both mods here are excellent, I can't decide which one to choose...

I will get dimensions later'(I have .ems files), Mike made copper plates for me and I did the mod for him.
Yes, heatsink grease everywhere and copper plates were attached to Quark's case with screws to prevent PCB motion inside enclosure, common problem with Quark's.

Yeah, I would just smother on the thermal paste, then tighten the screws and wipe up the excess that is squeezed out when tightened.

Zeropointbug: do you have dims for your clamp parts?

Generally: Would there be any sense to separate the power section from the brain section? To my knowledge it needs only some extensions to wires. It may be easier to put compact heatsinks to both fet sides and take the brain section which does not heat to more "safe" place to avoid short circuit and hit. Longer wires in this case are not length sensitive, I suppose? Just a thought...
