This is EFLUM180BLB a BL 180 sized brushless motor 3000kv used on alot of popular Eflite UMX aircraft.  This is opened but in new condition was plugged in to test if it was control unit that was bad and that was verified.  So my loss is your gain brand new motor at discounted price so i can replace the 2 in 1 esc/receiver that is bad since its not the motor.  This will be shipped via the USPS ground advantage.
