ECO II SERIES / HEAVY-LIFT POWER

Brushless Motor Platform

EMAX ECO II 6215

The EMAX ECO II 6215 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 × 63.2mm body, M6 threaded propeller shaft and 30 × 30mm mounting pattern. At 378g with wire, it is engineered for large FPV aircraft and heavy-lift propulsion systems.

Two 12S power profiles. 180KV for 18- to 22-inch propellers. 200KV for 18- to 20-inch propellers.

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.

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.

The 180KV winding supports the broadest published propeller range, while 200KV provides the higher-RPM choice for 18- to 20-inch propellers.

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

EMAX ECO II 6215 heavy-lift motor platform for 18- to 22-inch aircraft

Serious lift with practical value. The ECO II 6215 combines a 24N28P heavy-lift platform with two 12S winding choices for builders matching propeller size, current and thrust targets.

Flight Controller / VTX Warranty Policy

At weBLEEDfpv, we are committed to providing high-quality products. However, due to the technical nature of flight controllers and VTX's the precision required for installation, our warranty policy for flight controllers is as follows:

1. No Warranty Post-Soldering:

Once any soldering has been performed on the flight controller / VTX's, we are no longer responsible for replacements, repairs, or refunds. The process of soldering can introduce various factors that may lead to damage, and we are unable to control or verify the conditions in which the soldering was conducted.

2. Pre-Soldering Inspection:

Before you begin soldering, we recommend carefully inspecting the flight controller / VTX's for any potential issues. If any defects or issues are found prior to soldering, please contact us immediately for a replacement.

3. User Responsibility:

Soldering requires skill and experience, and improper techniques may result in damage to the flight controller, including but not limited to overheating or lifting solder pads. Please ensure you are confident in your soldering abilities before proceeding, as we cannot be held liable for any damages caused during installation.

4. Final Sale:

All flight controller sales are final once the product has been modified or soldered. We are unable to offer returns or exchanges on used or modified products.

**************************************************************************

⚠️ FPV DIGITAL SYSTEM NOTICE

HDZero, Walksnail, VTX systems, and ultra-micro FPV electronics generate heat quickly while powered and require proper handling during setup and troubleshooting.

Bench setup without airflow/cooling can result in excessive heat buildup.

Once powered, configured, firmware updated, soldered, flown, or modified, products are considered used.

Manufacturer warranty may apply for BNF drones and electronic systems.

**************************************************************************
