Manufacturer bench figures (RaceDayQuads bench, 50-100% in tens on three props per winding; 2650 KV at 14.8 and 22.2 V, 4000 KV at 14.8 V); real-world thrust varies with ESC, battery sag and prop condition.

Badass 2 1507 vs other 1507 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 400 g and 800 g is read off each maker's curve, straight-line between its two nearest bench points; 800 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 1507 motor: 1507 motors compared.

Thrust-to-weight with this motor

Four RDQ Badass 2 1507 motors at 868 g max thrust each give 3472 g: 2:1, the minimum to fly, up to 1736 g all-up; 4:1 (freestyle) up to 868 g; 8:1 (racing) up to 434 g.

Where this data comes from

RDQ publishes the Badass 2 bench table as the listing's own description image (1507_-_info_4.1.jpg): Item NO. / Prop / Throttle / Volts / Amps / Watts / Speed (RPM) / Thrust / Efficiency, six throttle points per run, temperature measured on the motor surface after 15 s at 100% in a 26 C room. Each winding's spec-block Peak Current / Max Power / Max Pull is its own GF4023 100% row (19.7 A / 437.3 W / 868 g at 22.2 V on 2650 KV; 28.2 A / 417.4 W / 798 g at 14.8 V on 4000 KV). Internal resistance is 160 mOhm at 2650 KV and 84 mOhm at 4000 KV. One row is not published: the 4000 KV GF3056 50% point prints 1899 g and 37.74 g/W, where the same winding's other two props read 239 and 328 g at 50%.
