I don't know if it's been posted somewhere, but I seem to recall people wanting to know how the motor was made (quality-wise), but the case is hard to get apart for some reason. Well, I found an article linked from the CC site which shows a nice pic of the inside and the rotor. Scroll down about 3/5ths...
Nice! it looks like 1 magnet from the feigao's; looks like it's about the same outside diameter, only with less copper used on the stator, which explains why they are relative light.
I thought the windings looked a little messy. I had my Wanderer apart the other day and the windings in that looked a lot tighter and filled more of the can.
