The engineers at Emax are always seeking ways to design the ultimate motor with brushless technology. In their efforts, they produced the ECO II Series, a new line of brushless motors further improving performance and durability while retaining the same affordability. Redesigned from the ground up, the ECO II boasts an all-new architecture. With a more rounded design paired together with thicker reinforcements, maximum durability is achieved. Finished with a reflective surface, the ECO II offers a sleek modern design destined to satisfy the need for both aesthetics and durability.

In order to improve the performance of its predecessor, the ECO II utilizes N52SH arc magnets over prior N48 magnets, allowing more powerful throttle response and higher RPMs to be achieved. More torque and thrust are generated, allowing pilots the flexibility to comfortably meet the demands of any racetrack or flight situation. The ECO II Series marks the next evolution in affordable brushless motor technology, bringing in a new era of performance for everyone.
