kV is 925, weight apx 800 grams - Lehners, Neu or other HQ motors have approximately the same power/weight ratio. Availability and my experience of Lehner motors was the base for my choice. I know there are tons of opinions in this area...
It will be interesting to analyze the logging data someday
Here is the lehner motor data on 14s = 50V from their webpage

The data @ 186A is the peak efficiency data
Motor type*2280/8, Windungen Windings*8, Spannung Voltage*50 V, Ri*8 mΩ
