Been a while since I set my Quark ESC up, but when done correctly it's still smoother than the MM. Don't get me wrong, the MM with the latest F/W is damn close to the Quark. The 80B is good for the 6T, but not the 5L. You need the 125B for the 5L motor. I have both the c40 6T(in my RC12L) and the c40 5L(was used my crt.5) I blew my 80B a while back due to my own fault, but my 125B still kicks butt in my Hyper7. I do use a external bec and Luciano's cap bank. Best go back to your settings and see what's wrong.
