I found this data on some production motors at another forum, apparently from Patrick who works at Castle Creations.
cm4600:
4675 kv
9.3 milli-ohms
3.0 Io (no-load current)
cm5700:
5721 kv
7.6 mohms
3.6 Io
cm6700
6811 kv
.0057 mohms
4.1 Io
cm7700
7695 kv
4.4 mohms
5.0 Io
The 4600 has close to the same specs as a feigao 380 8s, the 5700 is closest to a 380 7s and the 7700 is like a 5.5 turn 380. According to this, a 4600 on 3s is more powerful than a 7700 on 2s which may be true.
