Are you running a fan on the ESC this makes a big differance. Also Double check you motor wires.Ive had my MM overheat because my 5.5mm motor bullets werent soldersd correctly.This will be acompanied by cogging at low RPM.I also have a Tekno Neu 1515/1.5D and since my MMM is being repaired Ive been using my MM with a BEC set at 6.0 volts and a Novak fan on 4s in my 8T.
