Quark monster pro

[BrianG]

I really liked both of my Quarks (one sold with my Revo). Always VERY smooth no matter how slow you go. Even with the newer MM/MMM firmware, I still think Quark is smoother. Quarks simply operate differently in their start up routines than the MM/MMM. If you can get by the heat and warranty issues, and run 5s or lower, it is a good ESC. Personally, the thermal mod is needed though - the pad they use just isn't good enough for proper heat transfer. Adding a couple caps helps even more.
