EMAX ECOII-2004-2400KV Brushless Motor

This motor is officially rated for 4S to 6S LiPo battery packs (approximately 14.8V to 25.2V). Operating within this range ensures optimal performance and prevents damage from over-voltage. Always pair it with a suitably rated ESC.

EMAX recommends using 4-inch to 5-inch propellers. For 6S setups, smaller, less aggressive pitch props (e.g., 4x3x3) are often used to manage current draw, while 5-inch props on 4S or 5S can provide a powerful thrust profile for freestyle.

The motor uses a standard 19x19mm mounting hole pattern with M2 screws. The shaft diameter is 1.5mm. Ensure your frame and propellers are compatible with these specifications.

N52SH magnets have a higher magnetic energy density and better temperature stability than standard N48 magnets. This results in increased torque, higher maximum RPM, and more consistent performance under thermal load, leading to sharper throttle response.
