Manufacturer bench figures (T-Motor bench, three props across two KV: HQ 1050-3, T-Motor T10.5X5-3 and HQ 1145-3 at 500 KV on 12S (48 V) plus a second T10.5X5-3 run on 8S (32 V); the same three at 700 KV on 8S (32 V) plus a second T10.5X5-3 run on 6S (24 V); 10 throttle points (10-100% in 10% steps) on each); real-world thrust varies with ESC, battery sag and prop condition.
Thrust-to-weight with this motor

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-1331.html, where the report's own Type column reads "V3120 KV500" and "V3120 KV700". Identity with our retail listing is three figures shared to the digit - 148.1 g, which is the 700 KV block's Weight (Incl. Cable), a 5 mm shaft (block: IN5 OUT5) and the 700 KV winding itself appearing as a block and as a Type - on the one KV the retailer sells. The block and the report carry a second winding, 500 KV, which neither the retailer nor T-Motor's page title lists, so kv_options gains it; it weighs 146.7 g, has 76.35 mOhm against the 700 KV's 40.59 and a 0.95 A idle against 1.35 A. The block's Peak Current (10s) is that winding's own highest-current row truncated rather than rounded - 68.9 A is T10.5X5-3 at 500 KV on 12 S (68.91 A at 100%) and 79.4 A is T10.5X5-3 at 700 KV on 8 S (79.41 A) - so the spec-block cross-check lands on both windings. Its Rated Power also appears verbatim in each winding's own table (539 W is the 500 KV T10.5X5-3 12 S 50% row, 711 W the 700 KV T10.5X5-3 8 S 60% row), but at different throttle points, so that pair is recorded as an observation and nothing is derived from it. Three source facts recorded rather than repaired. First, this is a third T-Motor report template, newer than both the 2021 V2-era and the 2024 V3-era sheets (its images are dated 20260520): 10 throttle points in 10% steps, a Torque (N*m) column the older sheets do not have, an Operating Temperature column printing "/" on all eight blocks, and - the part that matters for checking - Voltage and Power rounded to whole numbers. The voltage x (current + k) offset check that the V2208 and V2306.5 sheets answered cannot be run here at all: every one of the 80 rows is consistent with its printed integer volts and watts being the rounded form of unprinted figures, and no offset can be either shown or ruled out at that resolution. Second, the prop sets differ between the windings and between voltages - HQ 1050-3, T10.5X5-3 and HQ 1145-3 all run at 48 V on the 500 KV winding with a second T10.5X5-3 run at 32 V, while on the 700 KV winding all three run at 32 V with a second T10.5X5-3 run at 24 V - and both tile joins were cropped and appended before that was accepted; the joins are seamless, with the merged Type cell's "V3120" and "KV500"/"KV700" landing on opposite sides of each boundary, so nothing is missing between the tiles. Third, the drawing writes three of its dimensions with a comma decimal separator (O19,00, O37,20, 56,10) and one with a dot (17.5) on the same sheet. Mount is left unpublished for the same reason as on the 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. Propeller names are as this sheet prints them (HQ1050-3, T10.5X5-3, HQ1145-3), with the brand prefixed.
