mmm + fiegao + Nue + muggy = hot hot hot

[Gooberseptember]

Ok im new to posting, but have read just about every thread i could for the last yr or so.

I am not new to brushless conversions. I have about 9 or so under my belt.

Here is my problem:
first conversion on muggy:
stock losi muggy
fiegao 10xl
12t pinion
max amps 5cell 6000mah lipo
MMM

This resulted in fried motor on second run. (smoked alot) The motor and RCM heatsink was so hot i could feel the heat from about 5 in away.
The first run was smooth, the motor was hot, but nothing hotter than what the fiegao normally gets.(i have had a few of these motors)

Battery was hot also. Sorry not temp gun.

So at this point i just thought i had a bad motor so i emailed Mike, but he seems to be busy. So no problem, i ordered another motor. This time a Neu.(from another site, mike was out of stock)

Setup #2.

Same as above ,but now with the Neu 1515/2.5d with out fins.(only one i found in stock)

Now i took it out and felt the motor every min for 4 min. The MMM fan kicked on and stayed on within the first min. The motor at end of min 4 was just hot enough that i could only hold my hand on it for a few seconds.

This is my problem.
There is no binding rolls smooth.
Pinion is set perfect.
The pig comes in aroung 12lbs.

MMM settings are set to low everything.(i thought it would run cooler, i could be wrong)

Any help would be great.

Oh yeah, both setups are as per MIke. So i trust them. ???
