Manufacturer bench figures (FlyFishRC bench, 24 V (6S), 1350 and 1850 KV on two 7in props, 50-100% throttle in tens); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from

Bench rows are FlyFishRC's own "Test report", the single description image the retail listing carries (the maker's site disallows this fetcher by name in robots.txt); the same image carries the spec table and the product drawing. Two windings at 24 V (6S) on HQ J75 and GF 7042, 50-100% throttle in tens. The sheet's 1850 KV block maxima - 2382.6 g, 1373.3 W, 60.02 A, the three figures the listing prints - are the GF 7042 100% row, and its 1350 KV block (2171.3 g, 1050.7 W, 44.75 A) is that winding's GF 7042 100% row. Only 1850 KV is sold on this listing; 1350 KV comes from the sheet and weighs 48 g against the 48.3 g published here. Three rows print an impossible thrust - 11059.6 g at 1850 KV / HQ J75 / 50%, 11070.6 g and 11071.6 g at 1850 KV / GF 7042 / 50% and 60% - and each prints an efficiency computed from it (22.12, 22.23 and 14.54 g/W), so both cells are left empty on those rows rather than repaired; their voltage, current, RPM and power are the sheet's and are kept. The product drawing marks the mount as "Ø 19" with a 4-M3 leader, a bolt circle, where the listing's spec block prints "Mounting pattern: 19x19mm", a square; the published figure is left as the block states it.
