Narrative:

Shortly after rotation/liftoff, uncommanded stabilizer trim was observed. Manual override stopped the event and, about 1 min later, the trim began to operate/runway again. As flight was VMC and in normal trim, a routine return to msp accomplished. No emergency was declared. No other problems occurred.
