Manufacturer bench figures (BrotherHobby 2020 bench, 8 throttle points per KV; 1550KV and 3100KV on 6S, 1900KV and 4150KV on 4S); real-world thrust varies with ESC, battery sag and prop condition.

VY 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.

Motor	KV	Prop	Peak thrust	At 400 g	At 800 g
BrotherHobby VY 1507	3100	HQ 343 Triblade	879 g at 655 W	235 W (1.7 g/W)	593 W (1.35 g/W)
T-Motor F1507	2700	T-Motor T3140 Tri-Blade	839 g at 543 W	188 W (2.13 g/W)	516 W (1.55 g/W)
RDQ Badass 2 1507	2650	GF4023 3R	868 g at 437 W	122 W (3.27 g/W)	389 W (2.06 g/W)

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 BrotherHobby VY 1507 motors at 695 g max thrust each give 2780 g: 2:1, the minimum to fly, up to 1390 g all-up; 4:1 (freestyle) up to 695 g; 8:1 (racing) up to 347.5 g.

Where this data comes from

VY 1507 bench sheets cover 1550/1900/3100/4150 KV; the 3100/4150 KV runs use a 3in triblade, the 1550/1900 KV runs a 5in. max_thrust_g is the sold winding's own best (owner ruling 2026-10-20: it comes from a winding the page sells; rows of other windings stay).
