My Quark Heatsink

[Serum]

The fets are attached to the bottom of the aluminum quark case

You're sure?

I wondered about just mounting the esc to an aluminium chassis with a thermal pad in between,should absorb a little shock and still conduct heat to the chassis.

Yep. I took the plastic cover and sides off and the ESC is made up of a couple layers of stacked boards (like the BK Warriors), but the bottom layer is attached to the case. You can do this too, but be careful because there is a small surface mount capacitor next to the LEDS that can get torn off if you aren't careful.

I've had great results with adding a heatsink as well. My temps went from 140F+ to 110F-115F depending on outside temps and driving.

I didn't open mine up an check, but I read on another thread that this was the case. I believe it was Brian G that opened it up and reported the fets attached to the case w/ thermal epoxy. Also, RC-Monster Mike put a heat sink on his attached to back of the case and reported great success.
