Manufacturer bench figures (VCI Hobby bench, 16500 KV at 2S (8 V) on two props, 19000 and 23500 KV at 1S (4 V) on four each, stepped by current rather than throttle); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from

The rows are VCI Hobby's own 'Testing Dates' table, published as an image in the Specifications tab of the motor's product page on vcihobby.com. THIS SHEET STEPS THE CURRENT, NOT THE THROTTLE: its columns are Voltage / Current / Thrust / Efficiency / Power / Temperature, the rows walk 0.50 A upwards to each winding's peak, and there is no throttle and no RPM column at all, so both are empty on every row here. VCI sells and benches this motor in three windings and all three tables are here; `kv_options` keeps the 16500 KV our retail source sells, so MAX THRUST READS 67.00 g, WHICH IS THAT WINDING'S OWN - it is the only one benched at 2S, and the 1S windings reach 38.20 g (23500 KV) and 33.90 g (19000 KV). Every row reproduces the sheet's two identities (printed Power = its own voltage x printed current, printed Efficiency = Thrust / Power). Two of the three panels land on a row: the 16500 KV's 5.5 A / 44 W is its GF 35mm-3 last row and the 23500 KV's 5.6 A / 22.4 W its GF 1635-3 last row, while the 19000 KV panel's 4 A / 22.4 W is above anything its own table reaches (4.00 A / 16.00 W). The panels give a per-winding internal resistance, 375, 275 and 185 mOhm, which is why resistance_mohm stays empty: this page is one motor in three windings and the field holds one number. Identity with our retail listing is 16500 KV, the 0703 stator (the panels print Ø7*L3 mm), 2S and 1.8 g including cable; the panels' shaft is written Ø1 mm.
