The KST X20 Helicopter Servo Pack includes three  X20-2208 Cyclic Servos, and one  X20-1035 Tail 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 tail servo offers 166oz/in of torque at a blistering fast 0.03 speed at 8.4V

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

KST X20-1035 HV Brushless Servo - 12Kg.cm 0.03s 70g 20mm

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.  

Features:

Standard size aluminum case
Low EMF design
Full metal gears
Dual ball bearings
HV compatible

It is an amazingly fast yet powerful and precise metal cased high voltage servo designed to be run directly from a 2S LiPo without needing a regulator.

KST also advise unlike any other servo, the X20 generates no counter EMF in any working conditions. It has an all-new design of circuit board, so your heli flybarless system and receiver will not be interfered with and will not display any weird behavior as a result.

In addition to the four heavy duty plastic output arms, which are similar to futaba 25T splines, the servo is supplied with two attractive red anodized aluminum arms with M2 threaded holes.

The extreme reliability and performance of these servos also makes them very suitable for use in film and motion picture industry special effect departments. They are also used in robotic, drone, UAV, UAS, academic research, military, and other highly demanding applications.
