So I came to the end of a run on Lipo(light on green), switched to red on the ESC for NiMH, and ever since get nothing. The ESC lights up as normal, I have tried fresh Lipo and NiMH batteries and switching through different modes on the ESC but still nothing. I drove the truck to a stop, so it's unlikely to be a dead ESC, I must have done something weird to the ESC when I switch to NiMH mode, but what?
