Let me jump in if I may, most ESC have a low voltage cut out, meaning your engine will shut down but you will still have power to the RX and servos. End result DEAD STICK, just as if you ran out of fuel or some other thing caused the motor to quit on a glow or gas Airplane. Although with the electric you might get just enough engine back after a short pause to assist in landing. Good luck with your new Nexstar.
