Looking for a speed controler for Neu 1515/1D motor

[2FastSS4U]

Just wanted to speak up for the quark, I'm running mine on a 13lb. savage with 5s apogee li-mn 5800mAh packs and even when I'm going balls to the walls full throttle it barely even gets warm, though it may be because of the integrated heatsink on my rx/esc tray that mike did for me. It's smooth as silk and stays cool as a cucumber if I'm easy on it.

P.S. Forgot to mention I'm running a 1515/2.5D
