Seems to do it randomly although did it two times in three runs at a race recently. Car would just stop in the middle of the track and I had to tell the marshal to turn off then on so I could continue the race. Not sure what error lights are blinking as after the marshal turns it off/on, everything is ok again. I plan to call/email Novak tomorrow but just wanted to see if anyone was having issues. Love the speed control, but it's very frustrating to have it ruin races!
