This is the original thread on that heatsink. The first post has pictures with it alone, with fans and installed on my revo with the quark. Heh, I was still running my 9XL in it back then. :002: Its got a Neu in it now.
The Quark/Neu or Quark/Lehner are still the best setups IMO. The Lehner and Neu motors are just about equal in my book as far as performance, but the Quark is still the best all around controller in my book. Smooth, plenty of programaing options, a built in LVC and with some sort of heat sink it handles plenty of power. Its not perfect, but its the best thing available right now IMO.
