Manufacturer bench figures (VCI Hobby bench, 1550 KV and 1850 KV at 4S (16 V), 8 throttle points (30-100%) per KV on one 6in and one 7in prop); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from

The rows are VCI Hobby's own 'Testing Data' table, published as an image in the Specifications tab of the motor's product page on vcihobby.com. VCI sells and benches this motor in two windings and both tables are here; `kv_options` keeps the 1550 KV our retail source sells, and here the two agree anyway - 1807 g on the 1550 KV is the larger figure. BOTH WINDINGS WERE BENCHED AT 4S (16 V), which is what the sheets print, although the 1550 KV panel states a 6S (24 V) rated voltage and the 1850 KV panel states 4S; every row's Power column is 16 V x its own current. Each panel lands on a row: 40.06 A / 640.96 W is the 1550 KV's 100% row and 42.81 A / 684.96 W the 1850 KV's. Identity with our retail listing is 1550 KV, the 2406 stator (the panels print Ø24*L6 mm) and 33.7 g including cable; the M5 shaft is new on this page, which carried no shaft figure at all.
