So I got my first chance to take out my Slash today. It would go about 30' and then stop receiving commands? I bought new batteries for the transmitter and a fresh charge on the battery. I checked to make sure the antenna was installed correctly, I even took all the slack of the antenna wire and moved it to the outside of the receiver box. Still, no good. The batteries are Rayovac, maybe the issue, not a good enough name to use? Any ideas?
