EMAX / ECO II series ECO II 3210 The EMAX ECO II 3210 brushless motor brings four KV options to 8–10-inch multirotor builds. The 800KV and 900KV versions support 6–8S; the 1050KV and 1200KV versions are specified for 6S. Each shares a 99g-with-wire platform, 12N14P architecture, M5 propeller shaft and 19 × 19mm four-hole mount. Weight 99g With 270mm wires Power system 6S–8S KV-dependent support Propeller range 8–10″ KV-dependent recommendation KV options 4 800 / 900 / 1050 / 1200KV Designed for the build The ECO II step into larger props. A common 39.1mm-diameter platform lets you choose the winding for the power system rather than changing your mechanical footprint. Match the propeller, ESC and battery to the specific KV/voltage combination; the published 8–10-inch range applies to the motor family, not every variant. Swipe to explore all four KV options → Find your winding Four KV options. One mounting footprint. Voltage, propeller range and winding resistance vary by KV. Choose the option that matches your battery, propeller and ESC setup. 800 KV Lower-KV choice with the broadest published propeller range.
