Manufacturer bench figures (GEPRC bench, 17000 KV and 22000 KV at 1S (4.2 V) on a Gemfan 1635 4-blade; current stepped 0.5-5.0 A and 0.5-7.8 A, throttle not published); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from

The rows are GEPRC's own 'Load Performance' table, published as an image in the description gallery of its product page on geprc.com. This whoop line uses neither of the templates GEPRC's bigger motors use: it steps CURRENT rather than throttle (0.5 A at a time), holds the pack voltage fixed, prints an Input (W) column that is exactly Voltage x Current, and leaves its own Speed (RPM) column EMPTY on every row - so throttle and rpm are empty here. Printed efficiency reproduces Thrust / Input on every row. The cross-check is GEPRC's own per-winding summary panel in the same gallery, which gives each winding one power and one pull figure: they are each table's last row to the digit. GEPRC sells this motor in two windings and publishes a table for each, so both are here: 17000 KV (10 rows, 39.21 g at 5.00 A) and 22000 KV (16 rows, 44.02 g at 7.80 A), which is why **kv_options gained the 22000 KV** - our RaceDayQuads listing sells only the 17000 KV version, and the KV variants of one motor belong on one page. Identity with GEPRC's own Specifications block is the 8.4x2.0 mm stator, 9N12P, a Ø1.0 mm shaft, a Ø10.7x14.4 mm body, 2.0 g and a 1S 380-530 mAh pack, which the 4.2 V bench confirms. The 22000 KV curve is the source's own shape: its efficiency falls to 1.24 g/W at 2.5 A, recovers to 1.43 at 6.0 A and falls again - nothing here is smoothed.
