Manufacturer bench figures (T-Motor bench, sixteen runs across three KV: at 1500 KV Gemfan D76, Gemfan 4023, Gemfan 5125 and HQ Duct 75MM*6 on 6S (~23.9 V); at 2850 KV the same four props on 4S (~15.8 V) and D76, 4023 and the duct again on 6S (~23.6 V); at 3550 KV Gemfan D90, Gemfan 4023 and Gemfan 5125 on 3S (~11.7 V) and the 4023 and D90 on 4S (~14.4 / ~15.6 V); 11 throttle points (50-100% in 5% steps) on each run); real-world thrust varies with ESC, battery sag and prop condition.

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-1097.html. Identity with our RaceDayQuads listings is four figures to the digit: the 2203.5 stator, a 3 mm shaft, 19.7 g - the block's Weight (Incl. Cable) at 1500 and 2850 KV, against 19.5 g at 3550 KV - and both KV the shop sells appearing as Specifications blocks and as report Types. Max thrust is the 2850 KV Gemfan 4023 6S 100% row, 1068.77 g, where the page carried none. At 176 rows this is the largest F-series sheet read and the second largest on the site: three windings over five report sections - 1500 KV on 6S, 2850 KV on 4S and again on 6S, 3550 KV on 3S and again on 4S - sixteen runs of 11 5%-step throttle points each. The prop sets differ by section rather than by winding: Gemfan D76, Gemfan 4023, Gemfan 5125 and an HQ Duct 75MM*6 at 1500 KV and at 2850 KV/4S, the same four less the 5125 at 2850 KV/6S, Gemfan D90, 4023 and 5125 at 3550 KV/3S, and the 4023 and D90 alone at 3550 KV/4S. All five section boundaries fall at an image edge and all were cropped and appended bottom-against-top; every join is seamless, so the differences are the manufacturer's. All 176 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 176, with no run carrying an offset: the largest per-run mean k is 0.003 A, which is inside what the two-decimal columns allow. kv_options goes from 2 to 3: T-Motor's own page title names 1500KV/2850KV/3550KV, the Specifications block carries all three as Test Items and the report benches all three, while our two RaceDayQuads listings sell the outer two - the "retailer short" shape, a fifth T-Motor sheet whose KV list is longer than a source's. Six source facts recorded rather than repaired. First, the spec-block cross-check lands on two windings of three and both are truncated: 462W / 19.5A is the 1500 KV Gemfan 5125 6S 100% row (462.46 W / 19.48 A) and 412W / 26.8A is the 3550 KV Gemfan D90 4S 100% row (412.35 W / 26.87 A). The 2850 KV block's 734W / 31.4A is on no row: the highest power anywhere in that winding's two sections is the 4023 6S 100% row's 654.01 W and the highest current is that same row's 27.96 A. That winding's 6S set is also the only prop set on the sheet short of one its own lower-voltage set runs - the Gemfan 5125 - so the block is consistent with a run the report does not print, and nothing is derived from either figure. Second, two runs in different sections print an identical RPM column: the 2850 KV Gemfan D76 4S and the 3550 KV Gemfan D90 4S both read 21021, 23111, 25210, 26798, 27672, 29845, 31248, 32596, 33982, 35105 and 39042, while their thrust, voltage, current, power, efficiency and motor temperature columns all differ. One of the two is a copy, and the arithmetic says which is the odd one without saying where its own figures went: 39042 rpm at the D76 row's 15.60 V is 2503 rpm/V, 88% of 2850 KV under a 23.88 A load, where the same prop and winding on 6S gives 44067 at 23.38 V, 1885 rpm/V or 66%; the D90 row's 39042 at 15.34 V is 2545 rpm/V, 72% of 3550 KV. Both columns are published as printed, because the sheet states no other value for either run. Third, and the same shape one column over, the 1500 KV and 2850 KV/4S sections print the identical Operating Temperature set in the identical prop order - 65, 67, 69 and 64 C for D76, 4023, 5125 and the duct - although one section runs at 24 V and the other at 16 V. Fourth, the block states max_cells per winding and our published 3-4S is only the 3550 KV one: Rated Voltage (Lipo) is 6S at 1500 KV, 4-6S at 2850 KV and 3-4S at 3550 KV, and the report benches each winding inside its own rating. The figure came off RaceDayQuads, which sells the 1500 KV and the 3550 KV, so it is right for one of the two pages our entry is built from and wrong for the other. Fifth, the Product Drawing dimensions the mount as a bolt circle and prints the symbol - "O12" on a leader to the pitch circle through four holes with "4-M2" beside it - so mount_mm stays unpublished for the tenth T-Motor page running. The same drawing calls out M5 on the threaded prop end where the block gives Shaft Diameter 3mm; here the block and RaceDayQuads agree, so shaft stays at 3 mm and this is the V2808/V3008 two-shafts reading with the drawing alone on the other side. Sixth, the two halves of the report were run at different ambient temperatures, so the Operating Temperature column is not comparable across the page: the 1500 KV and 2850 KV sections state 8 C ambient and the 3550 KV ones 15 C. Within that last section the two 4S runs also start a volt apart - the Gemfan 4023 at 14.66 V and the D90 at 15.84 V - the only two runs on the sheet at one nominal pack size that do. The row schema holds no temperature column, so these are here. recommended_props stays empty although the sheet benches a D76, a D90, a 4023, a 5125 and a 75 mm duct: a bench prop set is not a recommendation, and T-Motor states none. Propeller names are as this sheet prints them, with the brand rendered as Gemfan.
