Manufacturer bench figures (GEPRC bench, 1960 KV at 6S (25.2 V nominal), 10 throttle points (10-100%) on each of two 5in props (5131, 5136)); real-world thrust varies with ESC, battery sag and prop condition.

SPEEDX2 2207E vs other 2207 motors on 6S

The same thrust costs different power on different motors. Each line is one maker's own bench series (6S, its own prop), drawn as grams of thrust per watt against thrust, so a higher line makes that thrust for less battery current. Throttle percent is left out on purpose: it means something different on every maker's rig.

Power at 1350 g is read off each maker's curve, straight-line between its two nearest bench points; 1350 g is the highest thrust every motor here reached. Different props and rigs move these curves as much as the motor does, so compare rows on a similar prop. Peak thrust of every 2207 motor: 2207 motors compared.

Where this data comes from

The rows are GEPRC's own bench table, published as an image in the description gallery of its product page on geprc.com - the seventh brand this dataset has read a manufacturer sheet from. The E-series template is one winding over two 5in props, ten throttle points each (10-100% in 10% steps), with columns Type / Prop (inch) / Voltages (V) / Throttle (%) / Current (A) / Thrust (G) / Power (W) / Efficiency (G/W) / Temperature (C). It publishes no per-row RPM, so that column is empty here. **The Voltages column is the nominal 6S pack voltage, 25.2 V, repeated on every row, not a measured per-row figure**: the sheet's own Power column sits progressively below 25.2 x current as throttle rises, which is the pack sagging under load. Printed Efficiency reproduces Thrust / printed Power on every row. Identity with GEPRC's own Specifications block is 1960 KV, 12N14P, a Ø28x19.6 mm body, a 5 mm shaft, 6S and 34.5 g with wire - and the block's own Max Watt (1104.7 W) and Peak Current (44.57 A) are the 5136 100% row here to the digit, which is the cross-check. GEPRC sells this motor in three windings (1500, 1960 and 2020 KV) and publishes a sheet for one of them, the 1960 KV this page carries; the table is headed 2207E-1960KV. Sheet temperatures: 120.5 C on the 5131 run, 128.6 C on the 5136 run.
