I would check all your wiring to make sure something didn't let/come loose. The red and green lights blinking (constantly ?) alternately come on if a battery with too high voltage is used, the VXL-3m will then go into a failsafe mode. A 3S pack should not exceed or trip the over voltage protection, unless there is a possibility that your battery's polarity is reversed? Are you pressing and holding the EZ set button too long?
