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-984.html, where the motor is sold as VELOX VELOCE V2207 and the report's own Type column reads "V2207 V2". Identity with our retail listings is the 2207 stator, a 4 mm shaft, 34.3 g and both KV RaceDayQuads sells - 1950 and 2550 - appearing as Specifications blocks and as Types in the report. The block and the report carry a third winding, 1750 KV, which our two retail listings do not sell although T-Motor's own page title names all three, so kv_options gains it. The three blocks give 35.1 g incl. cable / 31.3 g excl. and 59 mOhm at 1750 KV, 35.2 / 31.4 g and 50 mOhm at 1950 KV, and 34.3 / 30.5 g and 43 mOhm at 2550 KV, so the published 34.3 g is the 2550 KV winding's weight including its cable; idle current at 10 V is 1.1 / 1.3 / 1.9 A. max_cells stays 5-6S, which is the rating of the two 6S windings: the 2550 KV one is rated 4S and is benched at 4S while the other two run at 6S. The spec-block cross-check lands on one winding of three and is the reason to run it: at 1950 KV the block's Max. Power (60s) / Peak Current (60s) is the T5147 100% row truncated (1003 W / 45.8 A against 1003.03 W / 45.89 A), and that row is both columns' maximum; at 1750 KV the 36.6 A is T5147's 36.64 A and is the current column's maximum, but the 804 W beside it is T5146's 100% row (804.31 W) and not the winding's highest power, which is T5147's 815.68 W; and at 2550 KV the 545 W is T5147's 545.98 W truncated while the 38.6 A is in no row of that winding's table and is above its own highest current, 38.18 A. All 132 rows match the efficiency printed beside them against the sheet's own power column AND reproduce that column as voltage x current, with no prop run carrying an offset (the largest per-run mean is 0.0023 A). Three source facts recorded rather than repaired: the 1750 KV T5143S 65% row prints the same 10.87 A as its 60% row, so its power falls (255.30 W against 256.48 W) while thrust rises 740.45 -> 841.01 g and its printed 3.29 g/W is above the 60% row's 2.89 - the row is internally consistent, it is the current column that repeats; the 1750 KV T5146 run gains only 32.84 g between 90 and 95% throttle (1523.67 -> 1556.51 g) where every other step on that run adds over 100 g; and the drawing calls out four M3 holes on a plain O16 between opposite holes, which is a 16 mm bolt circle and not the 16x16 square the mount column holds, so mount_mm stays empty. All three report sections were run at 19 degC ambient, and the surface temperatures at full throttle are 92-100 degC at 1750 KV, 92-100 at 1950 KV and 93-101 at 2550 KV.
