Manufacturer bench figures (RaceDayQuads bench, 6S / 24.00 V, 50-100% in tens; one prop at 1400 KV, four at 1900 KV, three at 2400 KV); real-world thrust varies with ESC, battery sag and prop condition.

Badass 2 2207.5 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.

Motor	KV	Prop	Peak thrust	At 1450 g
RDQ Badass 2 2207.5	1900	GF6040 2R	2058 g at 1037 W	563 W (2.57 g/W)

T-Motor F60 Pro IV V2 2207.5	1950	T-Motor T5150 Tri-Blade	1838 g at 950 W	659 W (2.2 g/W)

Power at 1450 g is read off each maker's curve, straight-line between its two nearest bench points; 1450 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

Bench table read off the listing's own description image (2207_-_info1.jpg), the same template as the other Badass 2 sizes. The spec block's own maxima land on the table: 1400 KV 33.3 A / 800 W / 1835 g is its GF7040 100% row (799.2 W), 1900 KV 45.7 A / 1096 W is the GF51499 100% row and its 2058 g Max Pull the GF6040 one, and 2400 KV 1473 W / 1989 g is the GF51499 100% row - whose current reads 61.4 A against the block's 60.4 A. Internal resistance is 108 / 84 / 56 mOhm across the three windings.
