To the cogging discussion: I have recently replaced all the stock magnets (which were glued in with typical Chinese "hot glue") with 2mm magnets I bought from Strong RC Motors. I had to slowly sand each magnet to about 1.7mm to make it fit (used sandpaper and custom magnet holder to avoid heating), a lot of work just for the heck of it.
I haven't wound this motor yet, but the cogging with tiny air gap and stronger magnets is way higher than in the original motor.
