OK, I test ran it and all seems ok. I, at this point, believe the the only problem was the caps. I left the esc out of the case and wrapped it in shrink wrap and epoxied the aluminum slab directly to a piece of 1/4" aluminum which is mounted to my chassis.
For some reason, I'm not liking it. The Quark PCB seems very weak with lots of flexing. I'm going to see if I can machine a delrin support for the connectors and pcb. If I can, I may just run it without the case to keep things cooler. I have to say at this point, that the Quarks do generate some heat.
A couple of pics...
Any constructive critism? I think I've gone overboard with this rather expensive of equipment.
