I'm sure it wasn't all that fun getting 16mags back in; I've never glued 16 mags in a 'wonder motor now that I think about it.
Gluing the magnets in wasn't really hard. No spaces, just push the magnet in place next to the last one. I glued them in place two at a time. Putting in a NS combination would hold the magnets in place. When putting in a single N next to a N, I would have to hold the magnet in place until the glue set up otherwise the repelling force would create a gap.
Testing the single magnet 8p is a good idea for comparison.
I was a little surprised that the kV wasn't higher on this first try.
Kev and others, what is the best ( not too hard) BW motor you have done so far for speed?
