The stator is completely rewind with 14 strands 0.23mm in 5T.
Small amount of epoxy is used to hold the wires in place. Tested with 6x4e at 4s , current ~35A. rpm....forgot....Not bad.
The stock neodym magnets are still very strong !
One comment is the shaft is not replaceable. Mine got bent on a few occasions after crash, and needed to be straightened with some skill.....
