I am currently experiencing the same problem with the same speed control. Ive been dealing with a website and I now have to send back the ESC. I looked at mine and it also didnt have a reset button and the steering still works fine. I tried adjusting the trottle knob and nothing happened. I charged the battery like it said and it ran for a short time then I put it on my dynamite charger and then nothing. I put in another battery and got the same result.
