I have a 1521 in my hand I just got in the mail from Chilli and it is not nearly as difficult to turn the shaft by hand as the other one I had made a few years earlier. Am I worried, no because it's a Neu motor and I know I can trust them. With some stuff from overseas, I dunno what to trust??
I talked to Neu quite some time ago about the difference in hand-cogging resistance between early and later production. They explained that (I'm counting on remembering accurately what they said but I may have this somewhat foggy) there was a production change that twisted the stator to have less low rpm cogging to help certain applications like helis.
