Hi guys, been asked to look at a Tamiya Porsche R/C which came from son in law late father. I’ve had very little to do with this stuff, and wondering if anyone can give me a bit of guidance. The control is Carson reflex wheel, it has an electronic speed control with a servo for steering. When all turned on, there is no response at all but the speed control has an LED which continually flashes and the ESC emits a continual beep. Any pointers please?
