Judging by the temps that Patrick posted, I reckon they'll be close to a genuine Neu in terms of efficiency. 172F is a pretty good temp after 15-20 mins of current spikes, and the maximum temps allowed are pretty high. If they're exactly the same design, then they'll probably be machine-wound like you say, JHautz.
Plus, I don't think Steve Neu would want poor-quality copies of his motors to be made, now that people know they'll be his design. They won't be as good as the genuine article obviously, but not too far off...and a lot better than a Feigao hopefully.
