Dual Sky DSM-51670 ECO V2 3520C 820KV Brushless Outrunner Motor

The Dual Sky DSM-51670 ECO V2 3520C is an 820KV brushless outrunner motor designed for fixed-wing RC aircraft and multirotor applications where reliable, efficient power delivery is a priority. Running at 820KV, it sits in a useful mid-range that suits a broad variety of sport and scale flyers, delivering smooth throttle response without drawing excessive current. The ECO V2 designation reflects Dual Sky's efficiency-focused winding approach, making this brushless motor a practical choice for pilots who want longer flight times without sacrificing performance.

Key Features

• 820KV rating makes it well suited to mid-size fixed-wing aircraft and multirotor builds running 3S to 4S LiPo power
• Outrunner configuration produces strong torque for direct-drive propeller setups without the need for a gearbox
• ECO V2 series winding is designed for improved efficiency, which translates to lower heat build-up during sustained use
• Stator size of 35x20mm places this motor in a capable class for aircraft in the 1kg to 1.5kg all-up-weight range
• Compatible with standard motor mounts using a 16mm bolt pattern, fitting common RC airframe and multirotor frame designs
