EMAX ECO II 2207 Motor

The EMAX ECO II 2207 is a reliable, high-torque brushless motor engineered for 5-inch freestyle and racing quads. Upgrading from the original ECO series, the V2 introduces N52SH curved arc magnets, significantly tightening the stator clearance to deliver sharper throttle response and superior low-end control. Available in 1700KV, 1900KV (optimised for 6S) and 2400KV (ideal for 4S), it brings premium durability and magnetic efficiency to high-performance FPV builds.

Key features

• N52SH curved arc magnets for increased torque and a tighter air gap compared to flat magnets.

• Durable 9x4x4 mm EZO bearings ensure smooth rotation and crash longevity.

• Hollow steel 5 mm shaft reduces weight without compromising structural strength.

• Rounded, machined aluminium bell handles heavy bando impacts and resists deformation.
