Manufacturer bench figures (T-Motor bench, five T-Motor props across two KV: T4943, T5143S, T5146 and T5147 at 1950 KV on 6S (24 V), T5143S, T5146, T5147 and T5150 at 2550 KV on 4S (15 V); 11 throttle points (50-100% in 5% 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-1110.html, where the motor is sold as VELOX VELOCE V2306.5 and the report's own Type column reads "V2306.5 V2". Identity with our retail listing is the 2306.5 stator, a 4 mm shaft and 29.4 g - the 1950 KV winding's weight excluding cable, the block giving 33.2 g incl. / 29.4 g excl. at 1950 KV and 33.8 g / 30 g at 2550 KV - and the 1950 KV RaceDayQuads sells appearing as a block. The block and the report carry a second winding, 2550 KV, which the retailer does not list, so kv_options gains it; that winding is rated 4-5S and is benched at 4S, while the 1950 KV one is rated 6S and benched at 6S. The block's Max. Power (60s) / Peak Current (60s) is that winding's own 100% row, truncated rather than rounded: 902 W / 37.4 A is T5146 at 1950 KV (902.36 W / 37.43 A) and 490 W / 33 A is T5147 at 2550 KV (490.07 W / 33.04 A), so the spec-block cross-check lands on both. The prop set differs between the windings - T4943, T5143S, T5146 and T5147 at 1950 KV, T5143S, T5146, T5147 and T5150 at 2550 KV - and both gaps were checked against the tile joins rather than assumed. Three source facts recorded rather than repaired. First, the Power column is voltage x current on 87 of the 88 rows but voltage x (current + 0.70 A) across all eleven rows of the 2550 KV T5146 run, a constant holding to +/-0.01 A; every row is exactly consistent with its own printed power and efficiency, and the three lowest-throttle rows of that run are the only ones where the missing 0.70 A is a large enough share of the draw to fall outside check_thrust.py's 6% band, so they are listed in ACCEPTED_EFF with the arithmetic. Second, the 1950 KV T5147 55% row draws 8.67 A against 50%'s 8.65 A and prints 211.90 W against 211.95 W - a current and power that barely move while thrust rises 752.63 -> 803.09 g and RPM 19309 -> 21823, which is why its 3.79 g/W is the highest efficiency in the winding and sits above the 50% row's 3.55. Third, the 1950 KV T5143S run reads 25.05 V at 50% and 25.06 V at 55% before falling monotonically, and it is the only run on the sheet whose voltage starts above 25 V. Mount is left unpublished for the same reason as on the V2208, V2306 and V2207 V3: the drawing calls out "Ø16" through two opposite holes with "4-M3" beside it, a 16 mm bolt circle, not the 16x16 square the mount column holds. Propeller names are as this sheet prints them (T4943, T5143S, T5146, T5147, T5150); sibling T-Motor pages whose sheets printed the blade count instead carry the same props as "... Tri-Blade".
