SunnySky X Series V3 X4120 480KV Brushless Motor

The SunnySky X Series V3 X4120 480KV is a high-performance brushless motor designed for large-scale fixed-wing aircraft and high-torque UAV applications. As part of the upgraded V3 series, it features a rugged design with high-temperature resistant magnets and a cross-shaped housing for superior heat dissipation. This motor is specifically engineered to provide a 20% efficiency boost and significantly more power over previous generations, making it an ideal choice for 30cc-class electric conversions and heavy-lift platforms.

Equipped with premium Japanese NMB ball bearings and high-purity oxygen-free copper windings, the X4120 ensures ultra-smooth operation and maximum electrical efficiency. Its robust 6mm shaft and durable construction are built to handle the extreme loads of large propellers while maintaining structural integrity during aggressive maneuvers. This 480KV variant is optimized for 6S LiPo power systems, delivering massive thrust and precise throttle response for a "locked-in" flying experience.

Key Features

• Advanced V3 Engineering: Redesigned for improved cooling and structural strength, offering a 20% efficiency increase over older models.

• Premium NMB Bearings: High-grade Japanese bearings provide reduced friction, lower noise, and a longer overall service life.

• High-Temp Resistance: Utilizes high-temperature magnets and specialized insulation to ensure consistent performance under high-load conditions.

• Superior Power Output: Capable of producing over 2400W of peak power, providing the torque needed for technical 3D aerobatics or heavy lifting.

• Dynamic Balancing: Every motor is factory dynamically balanced to eliminate vibration and ensure clean gyro data for stabilized flight.
