Manufacturer bench figures (BetaFPV bench, 19500 and 23000 KV on three whoop props at 4 V (1S), stepped by current); real-world thrust varies with ESC, battery sag and prop condition.

0802SE 0802 vs other 0802 motors on 1S

The same thrust costs different power on different motors. Each line is one maker's own bench series (1S, 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 20 g is read off each maker's curve, straight-line between its two nearest bench points; 20 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 0802 motor: 0802 motors compared.

Thrust-to-weight with this motor

Four BetaFPV 0802SE 0802 motors at 35.3 g max thrust each give 141.2 g: 2:1, the minimum to fly, up to 70.6 g all-up; 4:1 (freestyle) up to 35.3 g; 8:1 (racing) up to 17.65 g.

Where this data comes from

Bench rows are BetaFPV's own "Load Performance" sheet, the fourth description image of the retail listing; betafpv.com's own 0802 product page carries no such table. The image is 619x1200 at the retailer's CDN and no larger copy exists, but every cell is legible. The sheet is headed "0802SE 19500KV / 23000KV", so both windings are this one motor and both are listed - the retail listing sells the 19500 KV alone. Its table steps CURRENT: the Throttle, Speed (RPM) and Coil temp columns are struck through on every row, so no row carries a throttle or an RPM; both halves sit at a flat 4 V (1S). The 23000 KV half prints current to two decimals and efficiency to one. Two of its GF35mm-3B cells are defective and are published empty: the 2.50 A row prints 2.0 g/W where 24.2 g / 10.00 W = 2.42, and the 3.00 A row prints 2.0 g/W where 27.3 g / 12.00 W = 2.28; both thrusts sit on the run's own curve, so the efficiency is the wrong cell. The outline drawing dimensions the bell-end boss Phi1.5 mm and the prop shaft Phi1 mm, which is the 1 mm the listing publishes, and gives a 3-M1.4 EQS pattern on a Phi6.6 mm circle - a bolt circle, not the square mount_mm this schema carries.
