This ESC worked great with the Viper motor. I ran it for a year and a half in the Losi SCTE 2.0 at SC4x4 races with no problems. You get a tiny bit of cogging when you first start up and at super low speeds, but nobody drives that slow. This is an excellent ESC for the price. It's everything you need for power and speed. Viper's customer service is great, too.
