I bought this mostly because it was such a good price for a 60a ESC. I paired it with a 3900kv Neewer motor (from Amazon). I'm running it in an old RC10 and it is perfect. The ESC is programmable with a Hobbywing program card. If you are looking at the Hobbywing EZRun 60a, buy this instead. (Posted on 7/12/2015)
