1. 14 turns of 26awg
2. star. I also tried 30 turns of 30awg in delta configuration and got similar results
3. 6.5oz@4amps was done with a 6x3, but I've been flying with a 7x3.5 lately.

Unless you've got REALLY good stock magnets, I would recomend replacing them with 12 5x5x1mm n45 magnets, or your results will be a lot different. Another thing to consider is stator size (seems to be what everyone goes by when comparing motors). Mine is 20mm. I'm working on another one with a 23.5mm stator like the Chipsledde motor.
