The MM Pro has hopped over to a completely different setup at my house.
Now it is in:
Emaxx
MM Pro
Turnigy Lifepo4 4S
HV4400 upgraded with the sintered rotor w/5mm shaft w/upgraded endbell
geared 14/52 using Mod 1 gears
Sensored operation is Smooooooooth. Low speed operation is almost Rock Crawler Quality.
It's zippy fast too when you stab it!
I'm loving it. I may transplant this setup over into my E Revo.
