KDE Direct KDE5215XF 330KV
professional uav brushless motor. Specs read from manufacturer page ↗ and the datasheet ↗.
estimated Thrust here is modelled from rated power and propeller diameter via momentum theory, not measured. Indicative only, so do not compare it like-for-like against measured figures.

Parts this catalogue holds that fit this component, and the evidence behind each pairing. Fit is inferred from published specifications, not from having tried it. Confirm mounting and clearance before you buy.
rule of thumb The size conventionally run on a stator this big. Not a measurement -- check clearance and current draw before flying it.

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 →
