That data got these windings and propeller used.
I will dare to infer a bit about these windings. Only theory. Since I had come to test my motor.

It is clear that this motor in the area of 185Watts input gives us an efficiency above 80%.
If rewound to 15 o 16 turns delta. Give us a Kv. About 936 and 837.
To continue to sustain the level of efficiency, I think we should continue in the range of 185Watts input. And in that case for the 936kv, 15T. A propeller APC 10x5 and GWS 10x6 would be very small. And a APC 11x5.5 or APC 10x7 be very large. In this range of any type SF us serve as RPM exceeds limits. Since it be run around 8000rpm. In any case, insisting, only one APC 10x4.7.
With 16T delta and 837kv. A propeller APC 11x5.5 be run in rank. The GWS 11x7 be very large.

For more of this engine is needed to push a level of 70% efficiency.
