●Using 1715-type 5-pole Coreless motor, 1715 large motors 'speed is quicker,steering torque is greater,and using life is longer than 1515 small motors.
●Japan Noble 220°potentiometer,high accuracy,consistency,and one million times the high life potentiometer. 
●High resolution digital chip,stable performance,strong anti-interference ability,fast reaction speed,high precision,more delicate and smooth operation control.
●Aluminum alloy shell, processed by high precision CNC, better protection of the actuator product precision and cooling performance.
●Taiwan imported all metal gears, input and main gear wheel made of high strength material and hard iron manufacturing, reinforcing the strength and durability of gears, a higher degree of smoothness, even smaller gear virtual spaces.
●Double bearing design,imported precision miniature bearing, a greater degree of protection gear concentricity and smoothness.
