Im actually running a MM wit ha Mega ACn22/30/1 with the 5mm shaft. Its pretty insane. I am going to be getting the MMM soon but need to get new batteries first... I ran the velineon in my e-maxx for a while on 3s and it pushed it absolutely fine. never thermaled it. But I am sure it couldnt push my revo which weighs more now and is running a clutch.
