If I plug it into the hotwire the center red light comes on and the software shows me all my settings and that I'm running v255. I did all this in 1 night so it's not like I ran it then things went wrong, it's never seen the road yet. Do I have to revert back to v238? If yes how? I've got 2 new smc 6700 4s batteries I tried to see if anything changed, nothing. I tried holding down both buttons on the esc for 6 or so seconds to try and reboot, died. Also I am running a Futaba 4px, not sure if that matters since at 1st everything was working.
