Manufacturer bench figures (XILO bench, 50-100% in tens, four prop runs at 12 and 15 V; the sheet has no RPM column); real-world thrust varies with ESC, battery sag and prop condition.

Stealth 1404 vs other 1404 motors on 4S

The same thrust costs different power on different motors. Each line is one maker's own bench series (4S, 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 300 g is read off each maker's curve, straight-line between its two nearest bench points; 300 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 1404 motor: 1404 motors compared.

Thrust-to-weight with this motor

Four XILO Stealth 1404 motors at 351 g max thrust each give 1404 g: 2:1, the minimum to fly, up to 702 g all-up; 4:1 (freestyle) up to 351 g; 8:1 (racing) up to 175.5 g.

Where this data comes from

Bench table read off the listing's own description image (XILO_STEALTH_1404_Motor_Infograp_1.jpg): Volts / Prop / Throttle / Current / Power / Thrust / Efficiency / Operating temp, no RPM column. The sheet states volts only (12 and 15); they are recorded here as 3S and 4S, the spec block's own 'Volts: 15(4S)'. Its 351 g peak and 225 W are the block's Max Static Thrust and Max Power. Two rows print a power their own volts and amps do not reproduce, and in both the printed efficiency follows the printed power: the 15 V GF2540 50% row is 32.4 W (= 12 x 2.7) for 111 g at 3.43 g/W, and the 15 V GF3028 100% row is 225.0 W where 15 x 13.04 = 195.6, for 351 g at 1.56 g/W.
