Manufacturer bench figures (T-Motor bench, six props across four KV: T-Motor T9.5X5-3, HQ 1050-3 and T-Motor T10.5X5-3 at 400 KV on 12S (48 V) plus a second T10.5X5-3 run on 8S (32 V); the same three at 640 KV on 8S (32 V) plus a second T10.5X5-3 run on 6S (24 V); HQ 9050-3, T9.5X5-3, HQ 1050-3 and T10.5X5-3 at 900 KV on 6S (24 V) plus a second T10.5X5-3 run on 4S (16 V); T8.5X5-3, HQ 9050-3, T9.5X5-3 and HQ 1045-3 at 1050 KV on 6S (24 V) plus a second HQ 1045-3 run on 4S (16 V); 10 throttle points (10-100% in 10% steps) on each); 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-1330.html, where the report's own Type column reads "V3115 KV400", "V3115 KV640", "V3115 KV900" and "V3115 KV1050". Identity with our retail listings is three figures shared to the digit - 113.1 g, which is the 900 KV block's Weight (Incl. Cable), a 5 mm shaft (block: IN5 OUT5) and both KV the retailers sell appearing as blocks and as Types. The block and the report carry two further windings, 400 and 1050 KV, which no retailer we price from lists and T-Motor's own page title does not either - that title names no KV at all - so kv_options gains both: 400 KV is 113.4 g at 145.38 mOhm with a 0.59 A idle, 640 KV 113.3 g at 67.13 mOhm and 1.10 A, 900 KV 113.1 g at 38.08 mOhm and 1.57 A, 1050 KV 112.7 g at 33.84 mOhm and 1.79 A. Max thrust is the 400 KV T10.5X5-3 12 S 100% row, 4817 g, where the page carried none. The spec-block cross-check lands on all four windings, and reading it row-by-row is what shows the field is a per-column maximum rather than a row: on 400, 640 and 900 KV the block's Max. Power (10s) and Peak Current (10s) are one row - T10.5X5-3 at 100% (1982 W / 41.84 A, 1927 W / 61.83 A, 1894 W / 83.30 A) - but on 1050 KV the 1903 W is the HQ 1045-3 100% row and the 83.6 A the HQ 9050-3 one (83.61 A), two different runs. The current is also truncated on three blocks (41, 83, 83.6) and rounded on the fourth (61.83 printed as 62). Four source facts recorded rather than repaired. First, five cells in the report are printed wrong and each is left unpublished rather than reconstructed: the 400 KV HQ1050-3 60% and 70% efficiencies and the 400 KV T10.5X5-3 60% one all print "0.0" where the row's own thrust and power give 4.3, 3.8 and 4.5 g/W, so efficiency_gw is empty on those three rows; and the 900 KV HQ1050-3 60% current prints "408.08" A on a row whose 582 W at 24 V is about 24 A, so current_a is empty there. Second, the 900 KV T10.5X5-3 6 S power column prints 14, 16 and 19 W at 60/70/80% against the ~573, ~843 and ~1161 W its own voltage and current give; the power column is not part of our schema, so those three rows carry every other figure and the defect is recorded here. Third, printed power is voltage x current within the half-unit band the integer Voltage column allows on 179 of the 180 rows; the one exception is the 900 KV HQ1050-3 70% row, whose 840 W over 35.77 A implies 23.48 V against a printed 24, missing the band by 0.02 V. The voltage x (current + k) offset check is not runnable on this sheet for the same reason as on the V3120: with Voltage and Power both printed as whole numbers, k = 0 and k = 1 A are equally consistent with every row. Fourth, the drawing writes three of its dimensions with a comma decimal separator (O19,00, O37,20, and 51,10) and one with a dot (17.5) on the same sheet, exactly as the V3120's does. Mount is left unpublished for the same reason as on the V3120, V2208, V2306 V3 and V2207 V3: the drawing calls out "O19,00" on a leader pointing at the bolt circle with "4*M3" beside it, a 19 mm bolt-circle diameter, not the 19x19 square the mount column holds. This sheet also dates the report template that the V3120 entry called a 2026 one: its images are dated 20231129 and carry the identical column set - ten throttle points in 10% steps, a Torque (N*m) column and an Operating Temperature column printing "/" on every block, with Voltage and Power rounded to whole numbers - so that template predates the 2024 V-series sheets rather than succeeding them, and what selects it is the big-prop V31xx line, not the date. The two sheets differ in one field: where the V3120 block prints "Rated Power" (a mid-throttle figure), this one prints "Max. Power (10s)", and the lead is 18AWG 250mm against the V3120's 16AWG. Propeller names are as this sheet prints them (T8.5X5-3, HQ9050-3, T9.5X5-3, HQ1045-3, HQ1050-3, T10.5X5-3), with the brand prefixed. weight_g is the first-listed winding's Weight (Incl. Cable) from the Specifications blocks, 113.4 g at 400 KV (113.3 / 113.1 / 112.7 g at 640 / 900 / 1050 KV), named beside it; re-read 2026-10-20. The page used to show 113.1 g, the 900 KV figure, with no winding named (owner 2026-10-20).
