You sound like me. Electric is supposed to be easy. I have a pile of stuff that didn't work so well. Over the weekend I fried 2 motors somehow. One of them was a Neu 1515 2200kv. A phase wire was real loose just barely touching. Must have overheated. Now it just sputters. Oh well.
For a big boy like that you may need one of the big MGM esc's. You may run into thermal problems with the Quark even with the biggest heat sink added.
