Is there a Quark 125B thermal problem?

Here is a thread with more on the subject a long with some pictures http://www.rc-monster.com/forum/showthread.php?t=3861. I have done something similar to BrianG with my Quark. Since I have modified my ESC I have been really happy with it's performance. It has not thermaled since its been modified. I don't even use a fan on my esc, 1/8 buggy for 25 minute runs.

BrianG used a 3mm slab of aluminum between the FETs and the case and then it has the perfect spacing. That way is easier then the way I did mine. It really is easy to do. The hardest thing to do is open the case!

I just ordered another Quark for a CRT project, I'm sure I will modify it as well.
