Yeah, so many have told me that the 3gx isn't as good as its made out to be, I really are unsure. Be interesting to see how you get on with the spektrum, that may be a contender.
I was looking at your charger problems too mate, that's what's happened to mine, did you fix it??. I took it apart like you suggested, and there are a couple of burn marks on one of the tracks, I'm getting the same err message as you. Was thinking to bridge with wire, did it work??
