TMotor U8Ⅱ Lite Efficiency Type Multirotor UAV Motor (KV85 / KV100)

About T-MOTOR U8Ⅱ Lite Power Efficiency Multirotor UAV Motor KV100

T-Motor T-Motor U8II Lite KV100 Standard Version features an ultra-light design for extended flight times. With precise mesh protection, a self-cooling system, and heat-resistant wires, it ensures top efficiency and performance. Its curved magnet design unlocks maximum potential, making it a reliable high-performance brushless motor.

U8Ⅱ Lite Highlights:

Max. thrust ：9.1kg
MTBF：About 1000hours
Features：Industrial Grade, Waterproof, dustproof, low noise, large bearings
Industrial grade, dust proof, water proof.

"U Efficiency" motors (from U-series) are aimed for high end UAVs requiring long endurance. This kind of UAVs are usually for surveillance, cruise, security and protection, surveying and mapping.
Lightweight design allows you to fly longer, Industrial-grade dustproof and waterproof and anti-aging, greatly extends the working life of the motor. Curved magnets with precise tolerance control and rational magnet space for optimal motor magnetic circuit help improve motor performance. The motor uses imported customized bearings to extend the service life of the motor and ensure smooth flight and longer flight time.
