zpb, my Quark still gets hot too. Much hotter than my MM esc. That's why I was thinking that the caps weren't helping, but since I added the caps, I haven't blown anything and the cooling mod did stop the thermals.

I might go the my LHS and pick up a "better" radio. Didn't someone else just release a nice radio?

I need to get the new radio because MGM says that there wasn't anything wrong with my Compro. They are blaming my problems on the Spektrum, so I'll have to see.
