My old GTB was doing this also. I couldnt get it out of Lipo cut-off mode
it's like it froze there. Guys are the track couldnt even figure it out.
They said it was my sensor wire coming loose. They even shoo gooed it
in the slot and everything....no give... I figured my motor might have went out on me,
so I sent in my old stuff to novak and got a replacement GTB and motor.
Have not had a problem out of the new one so far.
Seems like this guy had that same problem I did.
