Manufacturer bench figures (T-Motor bench, three props across two KV: Gemfan GF3035, Gemfan GF3052 and T-Motor T3140, all tri-blade, on 6S (~23.3 V) at 2700 KV and on 4S (~15.2 V) at 3800 KV; 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 "Test Report", "Specifications" and "Product Drawing" images on tmotorhobby.com/goods-923.html. Identity with our RaceDayQuads listing is four figures shared to the digit on the winding that shop sells: the block's KV3800 "Weight (Incl. Cable)" is 15 g against our published 15.0 g, its Shaft Diameter is 2 mm against our 2mm, its Rated Voltage(Lipo) is 3-4S against our 3-4S, and the O18.9x29.7 mm body is a 1507 stator. kv_options goes from 1 to 2: the Specifications block carries both windings - KV2700 at 15.2 g, 131 mOhm, 3-6S, 0.6 A idle at 5 V, a 22 A 60-second peak and 519 W max power, and KV3800 at 15 g, 81 mOhm, 3-4S, 0.9 A idle, 23 A and 372 W - both 12N14P on a 24#AWG 100 mm lead, and T-Motor's own page title is "F1507 2700KV/3800KV". Max thrust is the 2700 KV T-Motor T3140 6S 100% row, 838.7 g, where the page carried none. All 66 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 66 to within the band the two-decimal columns allow, with no run carrying an offset, so nothing here has the V2208's or the V2306.5's constant. Four source facts recorded rather than repaired. First, the spec-block cross-check lands on the GF3052 100% row rather than on the table maximum: the KV2700 block's 22 A and 519 W are that row's 22.68 A and 519.74 W truncated, while the biggest row on its sheet is the T3140 100% one at 23.34 A and 543.46 W - so this template's "Peak Current(60s)" and "Max. Power(60s)" are one run's figures, not the sheet's. On the KV3800 half only the power follows that rule (372 W against the GF3052 100% row's 372.86 W); its 23 A peak matches no row in its own table, where the GF3052 and T3140 100% rows draw 25.17 A and 25.87 A. Second, the block states max_cells per winding - 3-6S at 2700 KV against 3-4S at 3800 KV - and our published "3-4S" came off the 3800 KV listing, so it is right for the winding the shop sells and wrong for the one this entry adds. Third, the Product Drawing dimensions the mount as a bolt circle and prints the symbol: "O12" on a leader to the red pitch circle through four holes at 90 degrees, with "M2*0.4" on a leader to one of them - a 12 mm bolt circle is an 8.5 mm square, so mount_mm stays unpublished as on the other T-Motor and Axisflying pages, and this 2019 drawing carrying the symbol is one more sheet against the "2024 lost it" reading. Fourth, the shaft is two figures again, but the other way round from the V2808 and the V3008: the block's Shaft Diameter is the 2 mm bell shaft our page already publishes, while the drawing calls out O5 with an M5*0.8 thread on the prop end. The drawing also writes its three lengths with a comma - 29,7 and 17,9 and 1,4 - on a sheet whose block prints "O18.9*29.7 mm" with a dot. The report's Operating Temperature column is a per-run motor surface temperature at 100% throttle for one minute against a 28 C ambient - 79.6, 82.5 and 85 C on the three 2700 KV runs, 61, 65 and 73 C on the three 3800 KV ones - and the row schema holds no temperature column, so it is here. recommended_props stays empty although the sheet benches three 3in props: a bench prop set is not a recommendation, and T-Motor states none. Propeller names are as this sheet prints them (GF3035, GF3052, T3140, each with "Tri-Blade" underneath), with the brand prefixed.
