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. Identity with GEPRC's own Specifications block is the 8.4x2.8 mm stator, 9N12P, a Ø1.0 mm shaft, a Ø10.7x15 mm body and 2.4 g. **max_cells was corrected 1S -> 2S.** Our RaceDayQuads listing prints "Input Voltage: 1S"; GEPRC's own block says "Recommended battery: 2S 380mAh-530mAh LiPo" and benches this motor at 8.4 V, which is a 2S pack - the retailer's figure is the one that cannot be reconciled with the manufacturer's own test. Its 0802 sibling, published on the same page, really is 1S and really is benched at 4.2 V, so this is not a blanket brand correction.
