No, this is something that just came up. It started with the sc and I was thinking it was the esc , because I raced with the buggy and truggy that day. When I got home I figured out its not the esc as a dx2 works fine on it. I started to think something was up when the expo when you scroll down and highlight the numbers click it does not blink on both any more. It switches from side to side all by it self. So I looked at the monitor menu and the numbers were all over the place back and forth, and now it does the same to my b and t . Im goingto call horizon tomorrow.
