Lehner XL2400 locked up...

Nope no spacers, just a couple washers next to the front and rear bearing. I also tested both bearing and they are as smooth as can be. I also ran my finger across the windings and they seem very smooth. Your "very long shot" seems to be the most probable thing, although I can't beleive the current can be so high... if it was that high I doubt the MM ESC could handle it also...
