Manufacturer bench figures (Axisflying bench, 1975 KV (Proxy Edition) and 2125 KV (Extreme Edition) at 6S / 24.00 V and 2725 KV at 4S / 16.00 V, on a BB4943.5 and a GF 51466; 20-100% in tens on the 6S windings, 30-100% on the 4S one); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from

Axisflying publishes the whole Black Bird V3 sheet as description images on its own product page: a SPECS table, a dimension drawing and a TEST DATA table of 52 rows - three windings on two props, 20-100% in tens at 24.00 V for the 1975 and 2125 KV and 30-100% at 16.00 V for the 2725 KV. Identity with the RaceDayQuads listing we price from is the stator (2207.3), the 1975 KV winding and the 32.6 g weight, which is the SPECS table's Weight (Excl.Cable); the page body states 36.5 g for the same motor including its 150 mm cables, so the two figures are the same motor with and without its leads. The brand sells the 1975 KV as the Proxy Edition and the 2125 KV as the Extreme Edition, both 6S; the 2725 KV in the SPECS table is the 4S winding, which is what its Rated Voltage row (4~6S/4S) separates. The spec-block cross-check lands on all three windings, each time on the GF 51466 run: Peak Current 44.7 / 53.7 / 48 A against 44.7, 53.7 and 47.9 A at 100%, and Max.Power 1070 / 1288 / 766 W against 1072.61, 1288.79 and 766.22 W. Max thrust is the 2125 KV GF 51466 100% row, 1950.54 g, which the body restates as "can get over 1.9KG and most current is about 50A"; the 1975 KV winding our source sells peaks at 1814.7 g. Four source facts recorded rather than repaired. The 1975 KV GF 51466 100% row prints an RPM of 23157 between a 90% row of 30326 and nothing above it, so that row publishes no RPM. The 1975 KV BB4943.5 run's printed efficiency rises at 70% (2.38 -> 2.45 g/W) before falling again. The 2725 KV BB4943.5 run's efficiency also rises at 100% (1.91 -> 1.98 g/W) and its 40-50% step adds 8.89 A for 209 g where every neighbouring step adds less current for more thrust. And the mount is a bolt circle, not a square: the drawing calls out 4-M3 on a circle 16 mm across and the body says "Motor mounting hole size: 4*M3 (16mm)", i.e. an 11.3 mm square in the pattern a frame sees, so mount_mm stays empty as it does on every other Axisflying page here.
