Manufacturer bench figures (BetaFPV bench, 25000 KV winding on a Gemfan 1208-3P and a Gemfan 1210-2P at 1S (4 V); 7 current steps per prop (0.5 A to 3.1/3.2 A), throttle not published); real-world thrust varies with ESC, battery sag and prop condition.
0702SE 0702 Brass Bushings vs other 0702 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.
| Motor | KV | Prop | Peak thrust | At 10 g | At 20 g | |
|---|---|---|---|---|---|---|
| BetaFPV 0702SE 0702 Brass Bushings | 25000 | GF-1208-3P | 25 g at 12 W | 6 W (1.55 g/W) | 10 W (1.98 g/W) | |
| BetaFPV Freestyle 0702 | 25000 | GF 1207-3P | 29 g at 15 W | 5 W (1.84 g/W) | 10 W (2.04 g/W) | |

Power at 10 g and 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 0702 motor: 0702 motors compared.

Thrust-to-weight with this motor
Four BetaFPV 0702SE 0702 Brass Bushings motors at 25.2 g max thrust each give 100.8 g: 2:1, the minimum to fly, up to 50.4 g all-up; 4:1 (freestyle) up to 25.2 g; 8:1 (racing) up to 12.6 g.

Where this data comes from
Bench rows, dimensions and the prop list are from BetaFPV's own "Outline Drawing / Load Performance" sheet image for the 0702SE on betafpv.com/products/0702-brushless-motors, which heads itself "0702SE 23000KV / 25000KV / 27000KV" and carries a table per winding; only the 25000KV block is this page. Identity with our RaceDayQuads listing is the whole spec block to the digit - 25000 KV, brass bushings, 1.42 g +/-0.03 (1.35 g without the connector), a 1 mm shaft 4.2 mm long, a 6.6 mm hole distance, M1.4 mount holes, 1S and 12.75 x O9 mm - and the same figures are BetaFPV's 0702SE column, not its 0702 one (1.52 g, dual ball bearings). Max thrust is 25.2 g, the GF-1208-3P top row, where the page carried none. The sheet steps CURRENT, not throttle: seven points from 0.5 A in 0.5 A steps to the winding's own maximum (3.1 A on the 1208, 3.2 A on the 1210), with the Throttle (%), Speed (RPM) and Coil temp columns struck through on every row - so every row here carries no throttle and no RPM. Every row's Input (W) is voltage x current exactly and its printed Efficiency is thrust divided by that power to the hundredth. The three M1.4 holes sit on a 6.6 mm bolt circle, which is a bolt circle and not a mount span, so mount_mm stays empty. Recommended props are BetaFPV's own Recommended Parts list for the page, replacing our derived whoop-prop class; the page's prose names the 1210 2-blade for a 25000 KV motor and the 1208 3-blade for 27000/30000 KV. This is the older 0702 line, not the Champion/Racing/Freestyle 0702 (2026), which is a separate product page and three separate pages here.
