My tekin redline is a 3200 kv 6 turn delta wound motor. It has the same rotor and can size as the castle 1/10 scale motors (smaller than the feigao 540 S rotors). I don't know how the turns would be so low for such low kv without it being 4 pole, although the rotor is not 4 magnets which sort of contradicts the 4 pole theory.
