Manufacturer bench figures (iFlight test report, 6 throttle points (50-100%) at 16 V (4S) on a 2540 and a 2X2X4 prop, as printed (no prop brand given)); real-world thrust varies with ESC, battery sag and prop condition.

Thrust-to-weight with this motor

Four iFlight XING 1303 motors at 198 g max thrust each give 792 g: 2:1, the minimum to fly, up to 396 g all-up; 4:1 (freestyle) up to 198 g; 8:1 (racing) up to 99 g.

Where this data comes from

iFlight's product page carries a TEST REPORT image (XING-1303-5000KV.png): the spec table, a drawing and a 12-row datasheet. It confirms 5000KV, 6.5 g with wire, Ø17.58x16 mm, 386 mOhm, 3-4S, 9x9 M2, a 1.5 mm shaft protruding 4 mm, 120 mm 26AWG leads and 12N14P (unusual for a 1303-class stator, published as printed), and its 6.13 A / 98.1 W peak is the 2540 prop's 100% row. The sheet prints a flat 16 V and power to the watt, so the efficiency column follows V x A unrounded; all 12 rows pass it. Max thrust is 198 g on the 2540 at 4S.
