I ran my Xerun 60A in my 1s 12th scale and I am completely sold on this ESC. Plenty of power, little to no heat and responds to settings. No Laptop needed thankfully!!! One tip for anyone that lacks punch out of the corner, check your total timing. Too much and all it does is rev really high but has ZERO torque. I turned down the timing on the motor to about 5-8 degrees and was a totally different beast.
