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.
