EMAX ECO III 2207 1900KV Brushless Motor

The 2207 ECO III for 5 inch quads

The EMAX ECO III 2207 1900KV is engineered for high-performance FPV drones, and the maker describes exceptional power, efficiency and reliability. It has a precision-balanced rotor and lightweight construction for smooth, vibration-free operation.

It suits 3S to 6S LiPo batteries and 5 inch propellers, and its low-resistance windings help with fast acceleration.

Specifications that matter

The framework is 12N14P, the bearing shaft is 4 mm, idle current is 1.5 A, internal resistance is 64 milliohm, peak current is 50 A and maximum power is 1260 W. The package includes the motor and an accessory set.

Match the ESC to at least the 50 A peak, choose a propeller that suits your battery voltage and balance it carefully. A well-balanced propeller on this motor pays off in cleaner video and cooler running. If you notice jello in the footage, check the propellers and the motor bell first, since they are the most common sources of vibration on a 5 inch quad.

Who it suits

Freestyle and racing pilots who want a solid mid-priced 2207 for a 5 inch build.

Choosing the right propeller

A 5 inch propeller with a moderate pitch works well with this motor on 4S, while 6S benefits from a lower-pitch propeller that keeps the current sensible. Test each propeller on the bench, watch the temperature and compare current at full throttle so you can choose a combination that gives snappy response without cooking the motor. Change one thing at a time, such as pitch or battery, so you know which change caused the difference.
