Manufacturer bench figures (iFlight test report per winding, 6 throttle points (50-100%) on two props (Nazgul 5140, Gemfan 51466): 1700 KV at 6S (25.2 V), 2450 KV at 4S (16.8 V)); real-world thrust varies with ESC, battery sag and prop condition.

Xing-E Pro 2306 vs other 2306 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 650 g and 1300 g is read off each maker's curve, straight-line between its two nearest bench points; 1300 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 2306 motor: 2306 motors compared.

Thrust-to-weight with this motor

Four iFlight Xing-E Pro 2306 motors at 1604 g max thrust each give 6416 g: 2:1, the minimum to fly, up to 3208 g all-up; 4:1 (freestyle) up to 1604 g; 8:1 (racing) up to 802 g.

Where this data comes from

iFlight's product page carries one TEST REPORT image per winding (XING-E-Pro-2306-1700KV.png and -2450KV.png, 1307x2000 each): a spec table, the drawing and a 12-row datasheet on Nazgul 5140 and Gemfan 51466. The page's text block states the windings as 1750KV and 2450KV, but the 1700KV test report, the shop's own KV selector (1700KV / 2450KV) and our retail source all say 1700, and the report is self-consistent: its 100% row, 25.1 V x 36.66 A = 920.2 W, is the Peak Current and Max Watt both documents print. So kv_options keep 1700 and the 1750 is recorded here as the text block's figure (two maker documents disagree; the self-consistent one wins). All 24 rows pass printed power = V x A and the efficiency identity. Max thrust is the 1700 KV winding's 1604 g on the Gemfan 51466 at 6S. The reports confirm 33.8 g / 33.6 g with wire, the 5 mm shaft protruding 13.5 mm, Ø29.5x32.2 mm, 16x16 M3, 12N14P, 85.63/55.6 mOhm, 160 mm 20AWG leads, N52H magnets and NSK 9x4x4 bearings; the input volts are 25.2 V (1700KV) and 16.8 V (2450KV), the bench pack of each run. weight_g is the first-listed winding's Weight (included wire), 33.8 g (33.6 g at 2450 KV), from the product page's Specifications text read 2026-10-20; named 1700 KV for the reason above (owner 2026-10-20: weight includes the cable; the page names the winding).
