OK, I was running my Quark yesterday and I got the same symtoms as ZPB. No torque. I opened the case and the internal caps were puffed. Since I did the "mod" I'm going to have to remove the slab from the case and try to replace the internal caps. I may also take this opportunity to "extend" the case to allow for more caps and possibly put 5.5mm sockets on the pcb so that I can remove the power leads should I need to...or is adding the sockets a bad idea?

Oh, will the blown internal caps cause the esc to act the way it is, or did I blow something else. I was trying to get my quark to work without thermalling, so I was running without the "cap bank." I was running it easy. 4S, 14/46 on a 9XL and taking it easy around the track.

I've gotta say, I haven't been impresses with the Monster Pro at all.
