What would you say if you could purchase one ESC and actually end up with multiple ones? That's similar to what you get with Losi's Xcelorin Brushless ESC's. The Xcelorin ESC's provide exceptional throttle response and overall performance, but they also include some very innovative software that makes it possible to fully customize you're ESC's profile. This is almost like having more than one ESC all in one case. We've put together a handy tutorial to demonstrate the functions of the PC software and show how easy and intuitive it is to use. While we use a 1/10-scale sensorless system in this demonstration, the setup is very similar for the 1/18-scale systems as well.
