How many poles is a Feigao 6xl?

A Feigao is 2 pole. One magnet N/S. A 4 pole is four magnet N/S/N/S and so forth. The higher the pole the lower the Kv, but you get more torque. There's a math that someone posted in another thread that explains this in real deep engineering detail (I have no clue where it is though).
