Manufacturer bench figures (T-Motor bench, eight runs across three KV: at 1300 KV HQProp HQ7040.3 and Gemfan GF7042 on 6S (~24.2 V); at 1500 KV HQProp HQ7040.3, Gemfan GF7042 and T-Motor T6143 on 6S (~23.9 V); at 1950 KV Gemfan GF51466-3 and T-Motor T6143-3 on 5S (~21.0 V) and Gemfan GF51466-3 on 6S (~25.2 V); 11 throttle points (30-60% in 5% steps, then 70-100% in 10% steps) on each run); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from

Bench rows, the two extra windings and the winding resistances are from T-Motor's own F90 page on its store t-hobby.com (Specifications and Test Report images, read 2026-10-17 through the local browser because the site sits behind a Cloudflare check). Identity with the RaceDayQuads 1950 KV listing: 12N14P, a Ø33.4x34.7 mm body, a 4 mm shaft, 5-6S, a 20AWG 230 mm lead, 46.6 g including cable and 45 mΩ - the block's KV1950 column to the digit. kv_options goes from 1 to 3: the same block carries KV1300 (76 mΩ, 0.95 A idle, 45.1 A peak, 1059 W, 46.6 g) and KV1500 (62 mΩ, 1.2 A idle, 47.1 A peak, 1089 W, 46.7 g) on the same body, shaft and lead, and the report benches both. Max thrust is the 1300 KV HQProp HQ7040.3 6S 100% row, 2360.61 g, where the page carried none. All 88 rows reproduce the printed power as voltage x current and the printed efficiency as thrust / power. The block's peaks are report rows: 1300 KV 45.1 A / 1059 W is the HQ7040.3 100% row (45.11 A, 1059.16 W) and 1950 KV 53.6 A / 1302 W the GF51466-3 6S 100% row (53.66 A, 1301.95 W); on the 1500 KV the two come from different runs - 1089 W is the HQ7040.3 row's 1089.99 W, 47.1 A the GF7042 row's 47.07 A. Three source facts recorded rather than repaired. First, and it is why 11 rows publish no RPM: the 1500 KV Gemfan GF7042 run prints an RPM column identical, all eleven cells, to the 1300 KV GF7042 run (8506 ... 21357), while its current, power and thrust differ from that run on every row; a copied column, so rpm is empty on that run. Second, on both 7-inch props the 1500 KV winding peaks lower than the 1300 KV - 2102.78 against 2360.61 g on the HQ7040.3, 1840.71 against 2116.55 g on the GF7042 - at more current, and its HQ7040.3 run tops out at 18501 rpm against the 1300 KV's 19617; every row is internally consistent and it is published as printed. Third, the sheet defines motor temperature as surface temperature at 100% throttle after 1 minute: 96 and 93 °C at 1300 KV (HQ7040.3, GF7042; ambient 27 °C), 99, 96 and 97 °C at 1500 KV (HQ7040.3, GF7042, T6143; ambient 27 °C), and 81, 88 and 93 °C at 1950 KV (GF51466-3 5S, T6143-3 5S, GF51466-3 6S; ambient 16 °C). Prop names are the sheet's with the brand prefixed: it prints "HQ 70403" for the HQProp 7040.3, "GF 7042", "T6143" on the 1500 KV and "T6143-3" on the 1950 KV runs, "GF51466-3". The drawing image on the page is a product photo without a mount dimension, so mount_mm stays empty
