Manufacturer bench figures (6S, T-Motor T5147-3, 100% throttle, 2150KV; manufacturer bench, weight 34.5 g (1950KV) / 33.7 g (2150KV) incl. cable); real-world thrust varies with ESC, battery sag and prop condition.
F40 Pro V 2306.8 vs other 2306 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 825 g and 1650 g is read off each maker's curve, straight-line between its two nearest bench points; 1650 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 2306 motor: 2306 motors compared.

Where this data comes from
weight_g is the first-listed winding's Weight (Incl. Cable) from T-Motor's "F40PROV Specifications" block, 34.5 g at 1950 KV (33.7 g at 2150 KV), named beside it; read 2026-10-20, so the retail listings' 34.5 / 33.7 g split is the two windings (owner 2026-10-20: weight includes the cable; the page names the winding).
