I think that the first thing everyone notices when they go to the neu from a feigao. I remember thinking the same thing when I tried to spin the neu for the first time.

I don't mean cogging with power. I mean free spinning, with no current flowing through the motor...

if it was a two pole motor, it would spin freely....

My new Ammo motor (35-50-2300kv) turns mich tighter than my old cc36-5700kv motor. I'm pretty sure it's the "dual sealed" bearings. I've ran it a few times now and it's starting to free up a bit, would imagine the lower kv windings would have less magnetic drag? or am I thinking about it wrong? or do the windings not have any effect on magnetic drag, just the magnets themselves?

Using the Neu, pletty, novak design, it will still turn rough. That is the design of the slotted (or caged, as i called it before knowing it was called slotted). Its the web the windings are wound on that make it rough to turn.
