The KST X20 V2.0 X20-2208 Cyclic Servo. The X20 Servos feature a brushless motor, full CNC aluminum case, and a complete set of Titanium gears through out each servo. The cyclic servos boast an incredible 347 oz/in (25kg.cm) of torque at 8.4V, and a crisp 0.07 speed. 

The developers at KST ensured nothing but the best components were utilized during construction of this servo, components as large as motors and gears, materials for the servo case,and small components such as the PCB board driving the motor. EMF currents in common DC voltage applications can generate large EMF spikes under operation, which can wreak havoc on other connected electronics. X20 servos feature a PCB board which minimizes EMF spikes, protecting other electronics from having to filter out the noise.
