Dual Sky DSM-51678 ECO V2 4130C 375KV Brushless Outrunner Motor

The Dual Sky DSM-51678 ECO V2 4130C 375KV is a brushless outrunner motor designed for large-scale electric RC aircraft and multi-rotor builds where sustained efficiency is the priority. The ECO V2 series is built around a low KV rating of 375KV, making this motor well suited to swinging large-diameter, low-pitch propellers at high efficiency rather than chasing raw RPM. At the 4130C stator size, this RC motor sits in the larger end of the outrunner range, targeting fixed-wing aircraft, giant-scale park flyers, and similar high-load electric powertrains.

Key Features

• 375KV rating delivers high torque and low RPM output, suited to large slow-turning propellers rather than small high-speed setups.
• Outrunner configuration places the rotating bell housing outside the stator, which improves torque characteristics and heat dissipation compared to inrunner designs.
• 4130C stator dimensions indicate a wide, relatively short motor built for efficient sustained power delivery in fixed-wing and multi-rotor applications.
• ECO V2 designation reflects Dual Sky's efficiency-focused winding and construction specification within the ECO line.
