The EMAX ECO II‑3214 is a high‑output external‑rotor brushless motor designed for heavy‑lift multirotor and 8‑10‑inch propellers. With four KV options from 450KV to 1050KV, it gives pilots and builders more flexibility to match the motor to different battery voltages, propeller sizes, and power requirements.
Multiple KV Options
Choose the KV that fits your setup. 450 KV is optimized for 12S battery / 9‑10‑inch prop, while 800 KV provides 6‑8S high‑thrust heavy‑lift performance. The 900 KV option is designed for 6‑8S multi‑rotor heavy‑lift flight. The 1050 KV option is designed for 6S and 8‑9‑inch propeller configurations. This range makes it easy to select the right winding for your aircraft without changing the basic motor platform.
Built for Reliable Power
The ECO II‑3214 features an anodized metal structure, multi‑strand winding, and three precision bearings for smooth and reliable operation. The robust external‑rotor design provides stable power delivery while maintaining a durable structure for everyday flying.
Secure Installation
The 19 × 19mm‑4*M3 mounting pattern provides a secure airframe connection, while the M5 threaded propeller shaft offers a straightforward propeller installation. Long silicone motor leads also provide flexibility when routing wires inside your aircraft.
