Manufacturer bench figures (iFlight test report per winding, 6 throttle points (50-100%) on 5050, 5.1x3.1x3, 5045, 5043 and 6045 props: 1800KV at 24 V (6S), 2450KV and 2750KV at 16 V (4S)); real-world thrust varies with ESC, battery sag and prop condition.

Xing-E PRO 2207 vs other 2207 motors on 6S

The same thrust costs different power on different motors. Each line is one maker's own bench series (6S, its own prop), drawn as grams of thrust per watt against thrust, so a higher line makes that thrust for less battery current. Throttle percent is left out on purpose: it means something different on every maker's rig.

Power at 1450 g is read off each maker's curve, straight-line between its two nearest bench points; 1450 g is the highest thrust every motor here reached. Different props and rigs move these curves as much as the motor does, so compare rows on a similar prop. Peak thrust of every 2207 motor: 2207 motors compared.

Where this data comes from

iFlight's product page carries one TEST REPORT image per winding (XING-E-Pro-2207-1800.png, -2450KV.png, -2750KV.png): a spec table, the drawing and a 30-row datasheet on 5050, 5.1x3.1x3, 5045, 5043 and 6045 props, 1800KV at 24 V (6S), 2450KV and 2750KV at 16 V (4S). They confirm all three windings, 33.8 g with wire for each, 12N14P, 16x16 M3, 81.5/46.8/41 mOhm, a 5 mm shaft protruding 13.5 mm, 160 mm 20AWG leads, N52H curved magnets and NSK 9x4x4 bearings, and each sheet's peak (35.22 A / 845.3 W, 42.63 A / 682.1 W, 50.03 A / 800.5 W) is its 6045 100% row. The Dimension line reads 28.5x33.1 mm, which is the drawing's 19.6 mm body plus the 13.5 mm shaft, so the body is published as Ø28.5x19.6. iFlight titles the motor 2-6S; it prints no cell rating per winding, and a bench voltage is not one. Three cells contradict their own row and are handled by the owner's rule (a contradicted cell stays blank): 2450KV 5.1x3.1x3 at 100% prints 36.68 A, but its 570.9 W and 2.437 g/W both give 35.68 A at 16 V, so the current is left blank; 2750KV 5050 at 90% prints 1315 g and 2.215 g/W, which disagree (618.9 W x 2.215 = 1371 g), so both are left blank; 2750KV 5045 at 90% prints 215.3 W where 16 V x 32.02 A = 512.3 W and its own 2.534 g/W agrees with 512.3, so that row stands (power is not stored). Every other row passes V x A and the efficiency identity. The retail listings' 4 mm shaft is iFlight's 5 mm. Max thrust is 1899 g, 1800KV on a 6045 at 24 V
