Was out with the kraton when reverse Went out..still goes forward just no reverse..tried to bind receiver.. Started the process..pushed and held bind button..turned on car..receiver blinked once..turned on transmitter and the esc started flashing red and now i have no throttle response..she just beeps and flashes two times (beep beep) (beep beep) i also noticed that the motor and drivetrain pulses with the beeps..steering is fine just no throttle..tried to reset throttle still nothing..what could be the problem..
