Specifications

The EMAX ECO II 2207 is a value-priced FPV racing motor sold in three windings — 1700 KV, 1900 KV and 2400 KV — each listed at $20.00. The 2207 stator size is the classic 5-inch freestyle standard, so this motor is the drop-in choice for replacing a burnt stator on a 5-inch quad or for building a budget freestyle rig without giving up the 16×16 mm bolt pattern every modern 5-inch frame uses.

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

Specifications

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

Three screw lengths are supplied because arm thickness differs between frames — check how many threads your frame plates leave before tightening, and use thread-lock on the motor bolts. For the differences between 2207, 2306 and 2807 stators, see our FPV motor size guide, and match the winding to your pack with the FPV LiPo battery guide.

Frequently Asked Questions

Which KV should I choose for 5-inch freestyle?

Pick 1700 KV if you fly 6S and want smooth, efficient throttle; 1900 KV works on both 4S and 6S and is the most common all-rounder; 2400 KV is the snappy 4S choice for punchy freestyle and racing.

Will the ECO II 2207 fit my 5-inch frame?

Yes. It uses the 16×16 mm mounting pitch that almost every modern 5-inch frame supports, so it drops straight into an existing build.

Can I run the 2207 on 6S?

The 1700 KV version is built for 6S. The 1900 KV version also handles 6S on most setups, while 2400 KV is intended for 4S — pairing 2400 KV with 6S will over-rev the motor.

What prop size suits the 2207?

Standard 5-inch props (around 5×4.3 to 5×4.8) are the matched size; heavier 5.1-inch props suit the lower-KV windings on 6S.

How do I replace a burnt motor?

Because the mounting pitch is identical, unplug the three phase wires, remove the four base screws, fit the replacement and re-solder the phases in the same order.
