Wow this little MM realy rocks with the bec,fan.It was pretty hot here today.I ran 4s and my Tekno Neu 1515/1.5d/f and temps were 160f on the MM.The motor seemed to run cooler on the MM ESC compared to the MMM though I raised the BEC voltage to 6.0 volts more rpm on the novak fan.I allready have a 25mmX25mm magnetic levitation fan wired to go.It came no connectors.I did hammer a few crossup wheelies never full throttle though.
