Specifications

The EMAX ECO II 2306 uses the 2306 stator — slightly wider and lower than 2207 — and is sold in 1700 KV, 1900 KV and 2400 KV at $20.00 each. Compared with the 2207 version it keeps the same 16×16 mm mounting pitch and the same 120 mm 20 AWG silicone leads, so it swaps straight into existing 5-inch builds. Choose the 2306 when you want a different torque feel on the same prop size.

Key Features

• Precision bearings and a hardened steel shaft
• Anodised bell for wear resistance
• 16×16 mm hole pitch — fits standard 5-inch FPV frames
• Multi-strand winding for higher copper fill
• 120 mm pre-soldered 20 AWG silicone wire

What Is in the Box

• 5 × M3×8 screws, 5 × M3×7 screws, 5 × M3×6 screws
• 1 × aluminium M5 nylock nut
• 1 × washer and screw for the shaft

Our 2207 vs 2306 vs 2807 motor guide explains how stator width and height change throttle response, and the FPV propeller guide matches prop pitch to the winding you pick.

Frequently Asked Questions

How is the 2306 different from the 2207?

The 2306 stator is a little wider and shorter than the 2207, which shifts the feel toward more torque at lower rpm. Both share the same 16×16 mm mount and the same lead wire, so they are mechanically interchangeable.

Which KV is best for 4S freestyle?

1900 KV is the safe, balanced 4S choice, while 2400 KV gives sharper punch on 4S. The 1700 KV version is better matched to 6S.

Can I mix 2306 and 2207 on one quad?

You can, since the mounting and wiring are identical, but mixing stator sizes changes how the quad handles — keep all four motors the same unless you are tuning a specific feel.

What ESC current do I need?

Pair the 2306 with a 30–45 A 4-in-1 ESC; the 45 A class leaves more headroom for 6S and heavier props.

Does the price include a prop nut?

The box lists the motor, three screw lengths, an M5 nylock nut and a shaft washer — prop nuts are normally already on the shaft when you receive the motor.
