Dualsky ECO 4120C 500kv Brushless Motor The ECO V2 has made great improvements in many respects. It brought new electromagnetic design, more competitive performance and efficiency, long-time endurance and water-proof. This ECO 4120C 500kv motor is designed to be the electric equivalent of a .46 – .55 2-stroke engine. Features Motor structure strength increased by 25% Optimised stress distribution and strength increased but it did not increase the weight. High strength and high toughness main shaft (HRC48) The rotor limit adopts 2 insurance modes of circlip and stainless steel chocks High temperature resistant, high toughness epoxy glue the impact resistance increased about 10G, and the survival ability is greatly improved. High precision double sides dynamic balancing Adopt NMB ball bearing, durable and low noise. ECO 41 and bigger, equipped with 3 ball bearings Optimised heat dissipation ways Motor working life significantly increased by 50% (same load and working environment) Modular design: main shaft, case and accessories (propeller mount and motor mount) are all compatible with the upcoming EA series. Besides, the design of propeller mount is completely implanted from GA series. Up to 500V insulation level. The stator is coated with insulating coating and completely insulated after winding. Waterproof splash. Rustproof main shaft, coil soak insulation, electrophoresis components and coated magnets make ECO V2 waterproof, and no problem working in wet or rain environment.
