rebuilding a 5700 two pole motor

[mwe-maxxowner]

I have a mm with a 2 pole 5700 geared 15/90 in a 2wd stampede that I run on 2s and 3s. Power is insane, but it likes to get hot.

Would a 4 pole 5700 run cooler?

Is this motor rebuildable as a 4 pole?

Does the 4600 have similar characteristics on 3s?

I love the truck like it is. The thing screams and will pull the tires up all the way to 50 (guesstimated).
