I am running the same set up you are talking about the MMM ESC and 2350kv EZrun motor and it works GREAT so far i ran it last weekend and the guy who help me built it runs a Neu motor and liked my motor and said the power was good.And i am running a Flightpower 4s battery and it runs great temps just right and i ran it for 15min and the battery was only down to 14.3 when i went to charge it.
