So I got some new GP 3700s today and had a lot of fun playing with my newly refreshed E-Maxx, but when I first put them in the truck and turned it on, the servos would work but there was no drive. The lights on the EVX were lighting up though, it was as if my motors were unplugged or something. I reprogrammed the EVX which according to the lights was successful, but still no action. After a few stressful moments of trying to figure out the problem, I tried switching the batteries and that seemed to fix it. This kinda made my blood boil (although it was already kinda boiling from the 100+ degree Vegas weather...) because I had just bought these batteries and I figured the one had to be bad. But after driving it (and tearing up my back yard like never before ), I figured it might be the EVX. Then, just to confirm, I tried each battery in my RC10 and they both seemed to work fine. So in your experience, what do you think might be the problem? Why would the EVX by picky as to which battery was plugged into which plug? Whatís the difference, theyíre both the same? I didnít have this problem with my other batteries. Also, after a while, my left steering was real responsive, but my right was real slow turning and returning to center, even on full throttle. I donít have this problem right off the charger, but about midway between a run, it will start to act up. Any advice would be appreciated.
