T-Motor V3120 KV700
professional fpv brushless motor. Specs read from manufacturer page ↗.
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.

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 →
