The X-U8II uses a FOC sine-wave driving solution with the matched T-Motor Alpha 60A ESC. The intelligent control algorithm helps the motor run efficiently, precisely, and stably, meeting the demands of professional UAV applications.
Strong Thrust and High Efficiency
Matched with the T-Motor G28×9.2 carbon propeller, the system delivers strong pulling force and efficient power output. It is suitable for industrial drone platforms that require long endurance, stable lift, and dependable performance.
Coaxial X8 Configuration Design
The coaxial upper and lower motor layout is ideal for X8 industrial drones, allowing higher thrust in a compact frame structure while improving payload capability and layout flexibility.
LED Status Indicator
The integrated LED indicator is combined with the motor mount, providing clear visual feedback and helping the pilot or operator improve control awareness during operation.
Easy Installation
The integrated arm set is designed for quick installation. It supports 25mm / 30mm arm tube diameter options, helping simplify assembly and reduce wiring complexity.
Matched Carbon Propeller Option
The G28 series carbon propeller is a classic configuration for the T-Motor power system. It provides high speed, high efficiency, and strong thrust performance. Custom propeller matching is also possible depending on the application.
