Manufacturer bench figures (VCI Hobby bench, 4500 KV at 4S (16 V), 5600 KV at 4S (16 V) on two props and at 3S (12 V) on a third, and 8250 KV at 3S (12 V), 8 throttle points (30-100%) per run); 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. The sheet PRINTS NO RPM COLUMN, so every row here carries an empty RPM. VCI sells and benches this motor in three windings and all three tables are here; `kv_options` keeps the 5600 KV our retail source sells, and here the maximum is that winding's own - 263 g on a GF 2512-3 at 4S. The 5600 KV is the one winding benched at two voltages: GF 2020-4 and GF 2512-3 at 4S (16 V), GF 3018-2 at 3S (12 V), which is what its 3-4S rated-voltage cell says; the 4500 KV ran at 4S and the 8250 KV at 3S. Every row reproduces its own run's identities (printed Power = its voltage x printed current, printed Efficiency = Thrust / Power). The 5600 and 8250 KV panels land on a row (8.45 A / 135.2 W is the 5600 KV's GF 2020-4 100% row, 11.72 A / 140.64 W the 8250 KV's), but the 4500 KV's 7.32 A / 117.12 W is ABOVE anything its own table reaches (6.36 A / 101.76 W at 100%), so that winding's cross-check lands nowhere. The panels give a per-winding internal resistance, 500, 300 and 175 mOhm, which is why resistance_mohm stays empty. Identity with our retail listing is 5600 KV, the 1204 stator (the panels print Ø12*L4 mm), 3-4S and 5.8 g including cable; the panels' shaft is written Ø1.5 mm.
