Neu 1515 & MMM Temp Poll

I know I've asked this before, but...

I put a TeknoNeu 1515/1Y and MMM and 4s in my E-Maxx that is now up to 11.5lbs. I ran hot so I got rid of the big Moabs and put some Terra-Izers on that are slightly smaller than stock.

I've geared everywhere from 25mph to 50mph and everywhere in between. Changing gearing doesn't change temps. After only 5 minutes of running, I get:
160*F on the motor
120*F on the MMM
115*F on the lipos

I know the faq says that 160*F is hot, so I am not happy with this. there is no binding in the drivetrain, all bearings are good. slipper is too tight if anything. mesh is right. i'm at a loss. Neu himself told me to just keep it under 200*F and not worry, but i keep reading how others are running the same setup with good temps.

i finally gave up and put a fan on it, but i'd like to take it off if i could get some help. any thoughts?







the 24V fan (running off 4s) got me down to 140*F after 5 minutes and 160*F after 10 minutes.
