TMotor U11Ⅱ Power Type UAV Motor (KV120)

About T-MOTOR U11Ⅱ Power Type UAV Motor KV120

T-MOTOR U11 II 120KV is a strong power king motor for multi-copter with heavy lift and large thrust. It's unique design provides swift airflow that cools motor 2.5 times faster than other T-motors with waterproof and dustproof features.

Handmade high-temperature enameled wire has excellent fire protection, industrial grade waterproofing, anti-aging and other properties, which greatly extends the service life of the motor. The precision winding ensures the tightness of coil and slot.It helps reduce the copperloss while improve the utilization. Adoption of imported high-quality bearing ，enables motor run more smoothly and longer with lower noise.

U11Ⅱ Highlights:

Optimal structure
Sine wave features
Military grade high-temperature resistant enamel led wires
Max. thrust increase by 4%
Flight time increase by 2%
Max. thrust ：14.16kg
MTBF：About 1000hours
Features：Industrial Grade, Waterproof, dustproof, low noise, large bearings
