EMAX ECOII 3530 Brushless Motor

The EMAX ECOII 3530 is a high-torque, large-format brushless motor built for fixed-wing aircraft, large multirotors, and long-range FPV platforms running 12"–15" propellers on 5S to 12S battery configurations. Built around a 12N14P stator with a Ø42.5 × 82mm profile and 6mm steel shaft, the ECOII 3530 outputs up to 2677W on 12S (280KV) and features enamelled wire leads terminated with male 4.0mm banana plugs for secure, low-resistance ESC connections. Four KV options cover everything from high-voltage 12S long-range builds to punchy 6S platforms.
