Manufacturer bench figures (Flywoo bench, 2750 KV on HQ 3*2.5*3, HQ 3*3*3 and GF4*2*2 props at 14.8 V (4S) and 22.2 V (6S), 50% and 100% throttle; 3750 and 4850 KV sheets also listed); real-world thrust varies with ESC, battery sag and prop condition.

Thrust-to-weight with this motor

Where this data comes from

Bench rows are Flywoo's own three test sheets (one per winding, 2750/3750/4850 KV) on its former product page "Co-Brand Dave_C & Flywoo Nin 1404 V2" (flywoo.net/products/nin-1404-v2-ultralight-fpv-motor, Shopify era), read from the Web Archive copy of 2021-01-27 with the sheet images at full size (1896 px) 2026-10-20; flywoo.net's current page carries no sheet. The sheets print Voltage, Throttle, Current, Thrust, Power and Efficiency, no RPM; every published row's Efficiency is Thrust over Power and its Power is Voltage x Current. Each sheet's first run, GF2.5*4*3, is left out: its 75% and 100% rows are printed under the higher voltage (22.2 V on 2750 KV, 14.8 V on 3750 KV, 11.1 V on 4850 KV) but their Power is the lower voltage times the current (2750 KV: 0.8 A x 14.8 V = 11.8 W, printed beside 22.2 V), and the 75% thrust (102 g on 2750 KV) is below the 50% row (173 g), so the run's cells do not describe one test. One more row is left out for the same defect: 4850 KV GF4*2*2 at 50% under 11.1 V prints 4.4 A, 189 g and 32.6 W, which is 4.4 A x 7.4 V. The 3750 and 4850 KV rows are windings this page's listings do not sell (Flywoo's page offered all three); max_thrust_g is the 2750 KV best, 399 g on HQ 3*3*3 at 22.2 V (6S). Full-throttle temperatures after a 10-minute load, which this schema has no field for: 2750 KV 61/76 C (HQ 3*2.5*3, 4S/6S), 63/79 C (HQ 3*3*3), 66 C (GF4*2*2, 4S). The same page's spec table is printed with every value one row below its label ("Weight(g)" beside "Phi19.4*14.1mm", "No.of Cells" beside the idle current), so only what its drawing dimensions on its own is taken: body Phi19.40 x 14.10 mm and a Phi1.50 mm shaft. Read by position, the table would give 9N12P, 9.5 g with a 3 cm wire, 4S-6S and 400 mOhm for 2750 KV; those are not published from a mislabelled table, so weight_g stays the retail listings' 8.7 g.
