T-Motor AT2820 KV1050
professional fixed-wing brushless motor. Specs read from manufacturer page ↗.
advertised This thrust figure is the one the vendor advertises, read from their product copy. The throttle setting, propeller and cell count behind it are frequently unstated, so it is a guide rather than a measurement.

How the metrics are calculated
TWR is max thrust divided by motor weight, motor only, static, excluding propeller and ESC. EFTWR scales that by hover efficiency and RPM headroom, so it equals TWR for a motor at 8 g/W and 10,000 RPM. Full methodology and the whole catalogue →
