Just received my (used) EX-1 Mars Radio / receiver. I got everything changed over (from my old radio system), and plugged up a battery. With the radio on, I get full throttle reverse. I have changed a few of the settings, but still same result. I would like a quick fix, as we are going to run a little today. I will cover the manual in it's entirety tonight, and tomorrow.
Any suggestions are much appreciated. Thanks!
