can not get my esc to arm to my radio. Did everything in the book it says to do and nothing. i hold full throttle and soon as i hit the switch it beeps and goes red then i full break and get beeping again and green light, then go nuetral and all the lights light up and then it beeps and goes red for a while then it turns yellow and beep continously and thats all it does. I dont know what else to do. Anyone?
