Just more food for thought. I'm joining this thread a little late but thought I would throw my experience with the MM and Neu 1515 1Y combo in an LST2. I've been running this setup for about 5 months now without any major issues. What I once thought was cogging was actually my brakes binding and causing stuttering. Believe me when I say this truck has been run hard and has had it's share of nasty crashes. The MM has even been ejected and dragged by it's wires a couple times. The only issue I had has been posted here and has to do with LVC settings on 5S.
This video clip is pretty typical performace. on 5S. I couldn't be happier with my setup. Would I recommend it? Not without mentioning issues others have had here. With that being said I will be doing a CRT conversion soon myself... MM/Neu
