this esc is great i have had it about a month now and have not had any issues with it i have had several other escs burn up on me and also had problems with the built-in bec on them not supplying enough powerand the built-in bec on this has plenty this one does not even get warm in fact with the cold temperatures of winter the esc is actually colder after a run than before i started i have it paired up with a gforce 2s 6500mah 40c battery and a hobbywing ez-run 3650 3300kv motor geared 26/84 in a 2wd stampede my only dislikes are the way the punch mode works and that you have to unplug the fan to connect a program card to it
