Dualsky GA8000.8S 160KV Single-Shaft Brushless Electric Motor
The Dualsky GA8000.8S is a powerful 160KV brushless outrunner motor designed for giant-scale RC airplanes and gasoline-to-electric conversions. Operating on 12S–14S LiPo power systems, it delivers up to 9,320 watts (12.7 hp) of peak input power for large 3D, aerobatic, sport, scale warbird, and UAV applications.
This is the single-shaft GA8000.8S version, Dualsky SKU 52061. It features a 10 mm output shaft and is designed for giant-scale aircraft traditionally powered by approximately 80cc–120cc gasoline engines.
Key Features
- Giant-Scale Electric Power: Designed for RC airplanes in the approximately 80cc–120cc gasoline-engine class.
- 160KV Winding: Optimized for large propellers and high-voltage 12S–14S LiPo power systems.
- Up to 9,320 Watts: Produces up to 9,320W (12.7 hp) of peak input power on 14S under Dualsky’s specified operating conditions.
- Single-Shaft Configuration: Uses a heavy-duty 10 mm output shaft for compatible propeller installations.
- High-Torque Outrunner Design: Its 24-slot, 28-pole configuration provides smooth power delivery and strong propeller torque.
- Giant-Scale Applications: Suitable for 3D, aerobatic, sport, scale warbird, and UAV aircraft.
- Gas-to-Electric Conversion: Provides clean electric power without gasoline, ignition components, exhaust residue, or combustion-engine vibration.

Installation and Safety Notes
- Use a properly rated 200A or larger high-voltage ESC.
- Use only a gas-style propeller rated for the expected power and RPM.
- Do not use an electric-only propeller with this motor.
- Provide adequate cooling airflow through the motor, ESC, and battery compartment.
- Use a reinforced motor-mounting structure appropriate for a giant-scale power system.
- Secure all mounting and propeller hardware before operation.
- Verify current draw, temperatures, propeller balance, and throttle settings before flight.
