I've just "solved" DrKiwi's suppo from is data + the value of no load current from suppo (1.6A at 10V).

Made some calc with this motor:

@10.7V with GWS 8x4DD : 17.97A - 13583rpm (DrKiwi had 19.3A - 13380rpm)
@11.2V with APC 8x6E : 33.32A - 11851rpm (DrKiwi had 36.7A - 11220rpm)

The difference between calcs and true results can be explain by the fact that I extrapolate from prop data in the 7000rpm range, and by other unknown various small factors.

@11.74V with APC 8x4E : 24.68A - 13917 rpm

so your results are just fine I guess.

BTW, that would produce around 1050 g of thrust, probably a bit more.
