The BEC is strong as I do not have brownouts with a Savox 1258. The heatshrink on the battery connector was loose. Motor cable are short so you cannot mount it on the side of a SCT chassis like you would do for example on a 2WD Slash LCG. There is no set button, no blinks or bips, to reprogram it you have to buy the 30 Dollars program card. When it is time to change the battery it doesn't cut throttle off like every other ESC, you still have full power until you fully steer to the left, in that moment throttle is cut and it is time to change the battery and then works fine. First time I noticed I thought it was faulty. So if you are going straight and only turn a bit to the left you will never know you battery voltage is too low risking to damage the battery.

EDIT: it has a set button but so far I could only calibrate the ESC with it)
