EMAX ECOII 6218 Brushless Motor

The EMAX ECOII 6218 is a large-format, high-torque brushless motor built for demanding 12S FPV platforms, heavy-lift systems, and long-range aircraft. Sharing the same 69.3mm diameter as the 6215 but with a taller 66.2mm stator height, the ECOII 6218 delivers greater torque and sustained power output for 18"–22" propeller configurations. Built around a 24N28P framework with a 6mm steel shaft, 30×30mm 4×M4 mounting pattern, and 400mm 14AWG silicone leads.
