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.
