I have been having problems with my radio. Had been working fine. Went to race and the car got about 100 feet and would stop. When I got closer it would start up again. I have 3 cars with Futaba receivers in them and they all did this. I am assuming it's the fail safe function. Why would this kick in tho? Is this something where I will have to send the radio in? Is there a way to get a hold of Futaba.
