EMAX ECO II 3220 Brushless Motor
The EMAX ECO II 3220 is a high-power brushless motor engineered for FPV performance tuning on large-format builds. With a 12N14P framework, three precision bearings, a steel shaft, and multi-strand winding, the 3220 delivers stable high-load operation across 6S through 12S power systems. Three KV options cover 8 to 11 inch propellers, with verified load-test data across eleven propeller and voltage combinations so you can dial in exactly the power curve your build demands.
