well, i just finished running mine until lvc cut (just shy of 20 minutes).

batts: 124*F
esc: 133*F
motor: 157*F
ambient: 82*F

it's now geared 24/65 = 42mph with 0.5" ballooning radius.
the fan was on it.

looking at your MMM settings mkrusedc, mine are just about 180* out.
MMM sttings:
Brake/reverse proportional w/ reverse
Brake 40%
Reverse throttle 40%
Punch 100%
Drag brake 20%
Start power low
Motor timing 0
Throttle curve linear

looks like you set yours up to haul @$$ and i've set mine up for low temps. i think i should try it your way.
