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.

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.
