Description

ECO II SERIES / HEAVY-LIFT POWER

Brushless Motor Platform

EMAX ECO II 6218

The EMAX ECO II 6218 is a high-torque external-rotor brushless motor for 18- to 22-inch multirotor propellers. Two 12S winding options—180KV and 200KV—use a 24N28P architecture, Ø69.3 × 66.2mm body, M6 threaded propeller shaft and 30 × 30mm mounting pattern. At 431g with wire, it is engineered for large FPV aircraft and heavy-lift propulsion systems.

01 / KV Selection

Match voltage and winding to the aircraft.

Published electrical limits and tested thrust values are transcribed from the official EMAX product specification and load-test sheets.

180KV

12S / 18- to 22-inch propeller

Lower-KV winding for the widest propeller range.

Peak current: 73.7A
Max power: 3510W
Resistance: 42mΩ
Idle current: 1.3A @ 10V

Bench highlight: 14.169kg thrust at 47.66V with JXF 22 × 10 CF two-blade; 73.66A / 3510.6W.

200KV

12S / 18- to 21-inch propeller

Higher-RPM winding for strong large-prop output.

Peak current: 79A
Max power: 3765W
Resistance: 39mΩ
Idle current: 1.5A @ 10V

Bench highlight: 13.857kg thrust at 47.65V with HQ 20 × 10 three-blade; 79.02A / 3765.3W.

EMAX ECO II 6218 selection guide for 180KV and 200KV 12S motors

Swipe horizontally to compare both KV options →

Choose from the complete aircraft backward. Match motor KV to battery voltage, propeller load, ESC rating, aircraft mass, airflow and required thrust. Published ranges are selection guidance; validate the final power system under realistic thermal conditions.

02 / Performance Envelope

Maximum tested thrust by KV.

Each bar shows the highest thrust recorded in the official test sheet for that winding. Both bars share a 14.169kg scale.

180KV · 47.66V14.169kg

200KV · 47.65V13.857kg

Maximum values were recorded with a JXF 22 × 10 CF two-blade propeller for 180KV and an HQ 20 × 10 three-blade propeller for 200KV. Bench results are configuration-dependent.

03 / Construction

Large outrunner hardware built around precision support.

01 / SHAFT

Steel Shaft

A 6mm bearing section supports the rotating assembly, while the M6 CW threaded propeller interface provides secure retention.

02 / FINISH

Anodized Structure

Anodized metal surfaces provide a durable finish for regular installation and service.

03 / MOUNT

30 × 30mm Pattern

A four-hole 30 × 30mm pattern accepts M4 mounting hardware at the airframe interface.

04 / WINDING

Multi-Strand Winding

Multi-strand winding is specified for the high-current operating range of this large outrunner.

05 / BEARING

Precision Bearing Support

Concentric bearing support promotes smooth shaft rotation under sustained large-propeller load.

06 / LEADS

400mm 14 AWG Wire

Long, heavy-gauge silicone motor leads provide routing flexibility in large-aircraft installations.

Motor leads	400mm 14 AWG silicone wire
Propeller specification	18–22 inches, KV-dependent
KV options	180KV / 200KV

One platform, two 12S profiles.

The shared mechanical package lets builders select 180KV or 200KV around the intended propeller load without changing the 30 × 30mm four-hole airframe interface.

Winding selection

The 180KV winding supports the broadest published propeller range, while 200KV provides the higher-RPM choice for 18- to 21-inch propellers.

Installation note: Confirm frame clearance, screw engagement, propeller retention, ESC headroom and cooling before operation.

EMAX ECO II 6218 heavy-lift motor platform for 18- to 22-inch aircraft

Serious lift with practical value. The ECO II 6218 combines a 24N28P heavy-lift platform with two 12S winding choices for builders matching propeller size, current and thrust targets.

05 / Electrical Specifications

KV-specific operating limits.

Use only the published voltage and propeller range for the selected winding. Confirm ESC current capability and thermal headroom for the complete aircraft.
