KST Micro Cyclic Servo MS325 with Hall Effect (Contactless) Sensor

No more scratchy, sketchy potentiometers. Hall effect sensors are taking their place.  Many of the glitches and quirks we face from our servos are due to the potentiometers becoming dirty or plain old, worn out. So here we have the new MS servo series from KST with its hall effect sensor and a carefully aligned magnet taking the place of the potentiometer. With this no contact, position sensing system we are a step closer to the day when sketchy, twitchy, double centering servos, will be no more.  

Reliability and precision are the name of the game with these alloy cased, hardened steel geared, digital coreless servos. Its very high specs is appropriate for many high demand uses including high speed gliders, helicopters and sport planes.

KST X10 Wing Servo V2.0

More power, new electronics, new engine, even better resetting accuracy. Upper part made of AI7075. The X10 is a new servo of the X series and the advancement of the KST DS225-MG-HV. The X10 differs from the DS225 by a new electronics with even better resetting accuracy. The motor of the KST X10 servo can be loaded with up to 10gk / cm. The upper part of the KST X10 is equipped with an Alloy Alloy Alloy 7070, which improves the durability and backlash in continuous operation clearly against the KST-DS225 MG. As with the KST X10 Mini, the KST X10 also uses a harder aluminum alloy on the upper part of the housing, which in turn further improves the freedom of play in the long run.

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.

The KST X20-1035 HV is approx standard size and has an output spline the same as similar Futaba servos, so many compatible output arms are available. Wirh an incredible 0.030 sec/60° speed and impressive 12 kg.cm torque the KST X20-1035 is appropriate for all fast large gliders, jets and helicopters on surfaces requiring very high speed response. This servo is also perfect for the tail rotor on 550 - 700 class helicopters.

In addition to the four heavy duty plasic output arms, which are similar to futaba 25T splines, the servo is supplied with two attractive red annodised aluminium 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.
