Manufacturer bench figures (iFlight test report per winding, 6 throttle points (50-100%) at 6S (25.2 V): 1500 KV on HQ 6*2.5*3 and Gemfan 6030-3, 1850 KV on Nazgul 5140 and Gemfan 51466); real-world thrust varies with ESC, battery sag and prop condition.
Thrust-to-weight with this motor

Where this data comes from
iFlight's product page carries one TEST REPORT image per winding (XING2-2506-1500KV.png and -1850KV.png): the spec table, a drawing and a 12-row datasheet. They confirm both windings, 38.2 g / 43.6 g with wire, 16x16 M3, 12N14P, 74.88 / 47.6 mOhm, a 5 mm shaft protruding 15 mm, 160 mm 20AWG leads and the 33.26 A / 817.5 W and 50.33 A / 1258.8 W peaks (each the 100% row of its own datasheet). Both reports' Dimension line reads 31.7x34.6 mm, but their drawings dimension the body at 19.60 mm, and 34.6 is 19.6 plus the 15 mm shaft protrusion, so the body is published as Ø31.7x19.6 (the length the BOB57 2506 report prints for the same winding). All 24 rows pass the efficiency identity. Max thrust is the 1850 KV winding's 1993 g on the Gemfan 51466 at 6S.
