Looks pretty neat job gwhy
As a bit of an aside, to do with internal hall sensors:
About a year ago, there was a discussion here about fitting internal sensors in the slots, and whether it mattered which slot you started with.
The theory emerged that with a dlrk wound motor (like the 80-100), it did make a difference. Depending on which slot you started with, you would either get neutral timing, or timing which was 30 edegrees away from neutral.
( The original discussion is around here viewtopic.php?f=30&t=15686&start=210#p358949
While preparing an 80-100 motor for use, I fitted it with two sets of halls, in adjacent slots.
Thought I would test out the above theory in a practical experiment, and the experiment seemed to illustrate the theory quite neatly:http://www.youtube.com/watch?v=_ghL8j_5cpY
Nothing really new here, I just thought it was a nice illustration of what difference choosing the slots makes.
