T-Motor M1103

Thrust data (T-Motor bench test)

Manufacturer bench figures (T-Motor bench, twelve runs across both windings: at 8000 KV GF1635-3 and GF2015-2 on 4S (~16.8 V), GF1636-4, GF2023-3 and GF65MMS-2 on 3S (~12.6 V) and GF65MMS-2, GF63MM-3 and GF3018-2 on 2S (~8.4 V); at 11000 KV GF1636-3 and GF2015-2 on 3S (~12.6 V) and GF2023-3 and GF65MMS-2 on 2S (~8.4 V); 5 throttle points (20-100% in 20% steps) on each run); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from

Bench rows, configuration and dimensions are from T-Motor's own "M1103 Product Drawing", "M1103 Specifications" and "M1103 Test Report" images on tmotorhobby.com/goods-1214.html. Identity with our two RaceDayQuads listings is six figures to the digit: 9N12P, a 1.5 mm shaft, 24AWG x 75 mm leads, a 4.6 g weight with wires against the blocks' 4.64 g (8000 KV) and 4.61 g (11000 KV) including cable, a four-M2 mount on a 9 mm circle, and the two windings the blocks and the report carry - 8000 and 11000 KV - which are exactly the two RaceDayQuads sells, so kv_options did not move. Max thrust is the 11000 KV GF2015-2 3S 100% row, 238.0 g, where the page carried none; the 8000 KV winding peaks lower, at 225.3 g, although it is the one benched on 4S. The spec-block cross-check lands on both windings and on the same prop: 284 W / 18.4 A is the 8000 KV GF2015-2 4S 100% row (283.9 W / 18.4 A) and 188 W / 15.2 A the 11000 KV GF2015-2 3S 100% row (188.2 W / 15.2 A), each truncated. All 60 rows match the efficiency printed beside them against the sheet's own power column, and 59 of the 60 reproduce that column as voltage x current to within 0.06 A. Five source facts recorded rather than repaired. First, and it is why 30 of the 60 rows publish no RPM: the RPM column is out of order within six of the twelve runs. Every row is coherent in its other five columns - throttle, voltage, current, thrust and power all rise together and thrust / power is the printed efficiency - and the RPM cell beside them is not ordered with them. The 8000 KV GF1635-3 4S run prints 35523.5, 33219.8, 12701, 14072.4 and 23830.9 rpm from 20% to 100%, and the 8000 KV GF65MMS-2 3S run is the clearest case: 26216, 39421.9, 47094.1 and 50443.6 rpm rise normally and then the 100% cell prints 6277.7. Each affected run's five printed values sort into a plausible monotone series, but which row each belongs to is not printed anywhere, so rpm is left empty on those six runs (GF1635-3 4S, GF2015-2 4S, GF1636-4 3S and GF65MMS-2 3S at 8000 KV; GF1636-3 3S and GF2015-2 3S at 11000 KV) rather than published at a row the sheet cannot support. The other six runs' RPM columns rise monotonically and are published as printed. Second, both blocks give the Voltage as 2-3s and two of the twelve runs are at 16.8 V, i.e. 4S; RaceDayQuads prints "Input Voltage: 2-4S" on both listings, which the bench supports, so max_cells stays 2-4S. Third, the one row whose printed power is not voltage x current is the 8000 KV GF2015-2 4S 100% row, which prints 283.9 W against the 299.9 W its own 16.3 V and 18.4 A give - and it is the row the block quotes as Max. Power (10s) 284 W. It is also the only overload point on the sheet: thrust rises 204.5 -> 225.3 g from 80% to 100% while current goes 8.6 -> 18.4 A and efficiency falls 1.43 -> 0.79 g/W. The printed power, not the product, is what the efficiency column follows there (225.3 / 283.9 = 0.79). Fourth, the drawing dimensions the body Ø14.5 x 13.55 mm where RaceDayQuads prints Φ14.4x14mm, and the published dimensions_mm is the drawing's; the drawing also puts a plain 9 between the top and bottom M2 holes and a plain 9 between the left and right ones, with "4-M2" beside them. Those holes are at 12, 3, 6 and 9 o'clock, so that is a 9 mm bolt circle and not the 9x9 square the mount column would hold, and mount_mm stays empty for the thirteenth T-Motor page running - but this is the first T-Motor page where the retailer states the same thing in words: RaceDayQuads prints "Mounting Pattern: Φ9mm, 4x M2". Fifth, the two RaceDayQuads listings print one identical spec set for both windings - 163 mΩ, 11.5 A continuous, 0.58 A idle at 3 V - where T-Motor's blocks differ per winding (0.48 A against 0.52 A idle at 4 V, 284 W against 188 W, 18.4 A against 15.2 A), so nothing per-winding is taken from the shop. Two 20% rows are in ACCEPTED_EFF for the usual micro-motor reason: at 0.5-0.6 A a current column printed to 0.1 A cannot reproduce the sheet's own power to 6%, and both rows match the power beside them. The GF63MM-3 2S run's efficiency falls 2.73 -> 1.91 -> 1.22 and then rises to 1.33 before falling again, every row internally consistent and no other run on the sheet doing it. Prop names are the sheet's own designations, unprefixed, because T-Motor states no brand for them; recommended_props stays empty although the sheet benches a 3018 and a 63 mm duct as well as the 1.6-2 in props. Its 8 description images are 4 marketing tiles dated 20220928 plus 4 of its own dated 20221010: 05 is the Product Drawing, the whole two-winding Specifications block and the first nine report rows, 06 and 07 the rest of the report, and 07-08 the two Testing graphs and the Contents panel. Two tile joins, both cropped and appended bottom-against-top, both seamless.
