>Would changing the centre diff fluid help much? See most people that run Brushless 8ights run 7000 or 10000 in the centre diff.

Increasing the diff fluid wheight will decrease unloading to the front tires which act like a big slipper. Thus traction normally will increase which results in an increase in amps too (as more power can be transfered to the ground). Higher Amp peaks will result in a hotter motor.

Very loose centerdiff = less amps, cooler motor

Those were my findings using an eagletree datalogger and comparing a center diff filled with grease, 10000 and 30000 silicone oil.
