60 mph mamba brushless setup for e-maxx, would this work?

[extremexmods]

Using 12 cells and a Mamba Max esc, could I use the wanderer 6XL? I know for a fact I will stick with a 12 cell setup. I see on the feigao motor chart (same as stats for tbe BK Wanderer) the Feigao 540 6XL has a max amp rating of 110, would this be constant? Also, on the kershaw designs website I see they have motor bearings rated for 70,000 rpm and 100,000 rpm. What would happen in real life with those rpm speeds?
