Not yet. Man those motor wires were mangled so I had to put fresh heat shrink on them and clean everything up. Will be using it pretty soon.
And to answer Jeremy1976:
Do you have any binding in your driveline? Have you tried changing gearing? Say to a smaller pinion or larger spur? You can't use the same gearing as you would on 3S without getting heat issues.
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.
