welcome to the world of hobby grade rc cars. I didn't read all of the posts so this may have been mesioned but if your esc won't run and is blinking you may have to program the esc, or some esc's blink if your throttle trim is not in neutral to prevent runaways but usually that will give you steering still. sounds like you may need to program your esc. usually consists of turn on esc with a fully charged battery while not connected to motor, push buttom, put throttle on controller to full forward push button, put throttle reverse full, push putton, put throttle in neutral push button and usually then you're finished...
