Dualsky ECO 4130C 290kv Brushless Motor

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 4130C brushless motor is designed to suit 90E-110E models and double wing 70e models, for example, Sebart Miss Wind. 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.
