Hot MMM - 05.07.2009, 07:26 PM

Hey guys, question for you all running MMM's. (alot of you)
I have a Maxx (3905) weighs about 12lbs. (5500grams).

I only bash, and my MMM must be running too hot, the fan kicks in everytime I go and run. Maybe 10 minutes in I will bring it over to me and The fan will run for about 30 seconds then shutoff cause it has cooled off a bit. EVERYTIME.
My motor runs great 125f tops and batts 100f at the most after 30 minutes but my MMM fan always runs. I dont want to damage the ESC by always running it at the point of almost thermalling (which did happen when a piece of a bush caught in the fan and it couldnt spin anymore).

I have great runtime and batteries arent being stressed so I do not know why the ESC is so heated. 30% punch, Normal Timing, no Drag brake. I have no rolling resistance except the COG torque from the medusa.
The one thing I can think of is that my servo is supposedly a current hog. Read on it that you need a robust power supply because it can pull up to 5amp. (dont hold me to it) It is a Power-HD 9660mg.

Look at my sig for motor and batteries. Any Tips?
