Manufacturer bench figures (T-Motor bench, four runs across two KV: at 6500 KV Gemfan GF3016 and HQProp HQ3020 on 2S (~8.4 V); at 5000 KV Gemfan GF2540 and HQProp HQ3020 on 3S (~12.2 V); 11 throttle points (50-100% in 5% steps) on each run); real-world thrust varies with ESC, battery sag and prop condition.

Thrust-to-weight with this motor

Four T-Motor F1204 motors at 171.75 g max thrust each give 687 g: 2:1, the minimum to fly, up to 343.5 g all-up; 4:1 (freestyle) up to 171.75 g; 8:1 (racing) up to 85.88 g.

Where this data comes from

Bench rows, configuration, dimensions and winding resistances are from T-Motor's own "Product Drawing", "Specifications" and "Test Report" images on tmotorhobby.com/goods-1119.html. Identity with our RaceDayQuads listings is five figures shared to the digit: both blocks give Φ15.5*15.6mm (a 1204 stator), a 1.5 mm shaft, 2~3S, 6.9 g incl. cable / 6.1 g excl. cable against our published 6.1 g, and the two windings the blocks and the report carry - 5000 and 6500 KV - are exactly the two RaceDayQuads sells. Max thrust is the 5000 KV HQProp HQ3020 3S 100% row, 171.75 g, where the page carried none; the 6500 KV winding was benched on 2S and peaks at 156.34 g, so the higher-KV winding is not the stronger one here. All 44 rows pass the efficiency identity - printed thrust / printed power is the printed efficiency on every one - and printed power is voltage x current on all 44 to within the band the two-decimal columns allow, with no run carrying an offset. Four source facts recorded rather than repaired. First, the spec-block cross-check lands on the 5000 KV block and not on the 6500 KV one: 72W / 6A are the 5000 KV HQ3020 100% row's 72.10 W and 5.96 A truncated, and the 6500 KV block's 7A is that winding's 7.04 A truncated, but its 60W stands 1.8 W above the 58.20 W that is the highest power anywhere in the winding's two runs, so nothing is derived from it. Second, the two windings' weights are printed identically (6.9 / 6.1 g) although their resistances differ by 100 mOhm, and our published figure is the excl.-cable one. Third, the drawing dimensions four M2 holes on a Ø9 bolt circle - a bolt circle and not a square pattern, so mount_mm stays empty - and writes its dimensions with a comma decimal separator (15,6, Ø1,5) as the V3115 and V3120 drawings do. Fourth, recommended_props stays empty although the sheet benches a 2540, a 3016 and a 3020: a bench prop set is not a recommendation, and T-Motor states none.
