The KST Servo Programming Tool #1 is used for programming KST V6 and V8 servos without the need for a PC or other computer.

This tool has a simple press-button interface that allows the servo mid point and end points to be set. It also allows the direction of rotation to be reversed.

Tool #1 User Guide

1.1. When using with KST X08 and X10 servos power the Tool#1 using any 4.8V to 8.4V DC power source with an XT60 plug (eg a 2S LiPo battery). The exact same output voltage that is fed into the tool is output to the servo, so using a 3S or higher voltage LiPo will irretrievably damage any X08 or X10 servo. The tool DOES NOT regulate the voltage down to a safe level for the servo.

1.2. The voltage input needs to be set according to the working voltage range of different models of KST servos. Do not input high voltage at will. The correct voltage must be used in order not to burn the servo out. For example: if programming a KST X08 V6 servo, the working voltage range is 3.8V – 8.4V, so the input voltage range must be 4.8V-8.4V DC. Alternatively if programming a KST X20-12-M 835-1 servo the working voltage range is 9-13V, so the input voltage range must be 8.4V DC.

2. Output interface: There are two rows of contacts, for programming one servo. The second row is spare. To connect the servo, orient the servo plug so the orange wire is aligned to the "S" mark, and the brown wire to the "-" mark.
-- = servo negative = brown
+ = servo positive = red
S = servo PWM signal = orange

3. Power-on and setting operation steps

3.1. Connect the power supply. After power-on, Tool#1 will enter the self-test. After the self-test is successfully completed, the buzzer will sound twice, and the orange power light of P_LED will blink. You can now connect the servo.

3.2. After checking the correct voltage connect the servo to the RC plug port. After connecting the servo the Tool#1 will automatically recognize this and output a 1500us PMW signal to command the servo to the midpoint location. At this time, the LED below 1500us will turn red and the Tool#1 enters the midpoint setting mode.

3.3. Midpoint setting: After entering the midpoint setting mode, press the "+" and "-" buttons below the 1500us label to set the required servo arm position for the midpoint PMW value, then press the Enter button to confirm. After the confirmation is successful, the buzzer will sound once. This indicates that the midpoint setting is completed and the Tool#1 enters the left and right stroke setting mode.

3.4. Left and right stroke setting: Press the "+" and "-" buttons below the 1000us label to set the max output arm movement in the low PMW signal direction. Then press the "+" and "-" buttons below the 2000us label to set max movement in the other direction. Then press the Enter key to send this info to the servo. The buzzer will sound once to indicate that the left and right stroke setting has been successfully made. The orange power light of P_LED will also start flashing, indicating that all operations have been completed and Tool#1 will enter waiting state, ready for another servo to be connected.

3.5. To only set the servo midpoint position, enter the midpoint setting mode and press the Enter button twice after the setting is complete. To only set the left and right movements, after entering the midpoint setting mode, press the Enter button once to enter the left and right stroke setting mode. After the setting is completed, press the Enter button to complete the servo setup.

4. Use of "CW/CCW" button

4.1. CW = clockwise; CCW = counter-clockwise.

4.2. After entering the left and right stroke setting mode, press the "CW/CCW" button to reverse the servo rotation for a given change of input signal. Then press the Enter key to confirm.

5. The Reset button. The Reset button only resets the Tool#1, and does not reset the connected servo.

The KST Tool #5 is an advanced programming device specifically engineered for precise tuning and adjustment of KST V6 and V8 Servos. This tool empowers users with complete control over their servos, ensuring optimal performance and customization.

Key Programming Features:

• Adjust Right Servo Travel: Fine-tune the servo's right-side travel precisely to achieve the desired motion range.
• Set Servo Center: Fine-tune the servo center for optimal alignment and responsiveness.
• Adjust Left Servo Travel: Precisely set the servo's left-side travel for desired movement deflection.
• Servo Reversing: Quickly and easily reverse the servo for different applications or requirements.
• Soft Start Function: Toggle the soft start option on/off for smooth and controlled movements.

CAUTION INPUT VOLTAGE = OUTPUT VOLTAGE!

It's crucial to not exceed the servo's maximum allowed supply voltage.
Use a 5V supply or a 2S LiPo.

The KST Tool #5 Professional boasts a user-friendly interface, facilitating straightforward and accurate programming of your KST servos for diverse applications in model-building and robotics control systems.

Optimize your servo performance with the precision control offered by the KST Tool#5 Professional, ensuring tailor-made motion applications for various user needs.

See the Instruction Manual PDF below for more info.

The KST Servo Programming Tool Card #5 is used for programming KST servos without the need for a computer.

The Tool Card #5 is an updated version of Tool Card #1. The updated Tool Card #5 features a user friendly interface for setting the servo neutral point and end point. The knob design makes the servo parameter adjustment easier and more intuitive. It also allows reversing the direction of rotation. With this tool, the servo parameter adjustment will be much easier than ever.

Servo Programming Tool Card #3 - A programming device for KST V6.0 and V8.0 servos, it is a very useful tool that makes it possible to not only change the frequency of the servo but also to set the neutral position which likewise adjusts the full travel. This gives the ultimate perfect centering of the servo, a handy tool!

Operating instructions

1. Connect the device to a 6-9V power supply, and the frequency indicators will start to flash.

2. Connect the servo to the servo port. The device will detect the servo frequency and illuminate the corresponding frequency indicator light.

3. Press the toggle frequency button to switch between frequencies. Press enter to select the frequency of the servo in use.

4. Use the dial to center the servo, and press "Enter" to confirm. Press down on the "Neutral set" dial to reset the device.

Characteristics

Recommended for thermal gliders up to max. 500 g take-off weight
Optimized for F3K, F5K and RES models

KST delivers once again with the world beating KST X06 V6, a new 7 mm thin servo weighing only 6.4g. Perfect for discus launched gliders (DLGs) and many smaller models. The incredibly slim casing is crafted from 7075 aluminium alloy, so not only do these servos look fantastic but they are also very rigid and robust. The new V6 version has the same great specifications as the old servo, but is also programmable using a PC based or a press-button programming tool.

The KST X06 has a hardened steel drive train and a coreless motor capable of running all the way from 3.8V to 8.4V (1S to 2S LiPo) making these WV (wide voltage range) servos will deliver the power and reliability you need. Although some say this tiny servo is too small for 1.5m DLG aileron surfaces it actually has more torque on 2S LiPo than a KST X08 has on a 1S battery.

The accessories include four strong nylon output arms, two double sided, and two single sided, one of which is low profile. This means that when the servos are mounted one in front of the other the control rod of the front one won't foul the rear one.


KST X06 Features

• Ultra slim 7 mm body
• Compact and light weight design
• Good torque and speed
• Wide 1S to 2S LiPo voltage range
• Excellent heat dissipation
• 7075 Alloy casing
• Hardened Steel gears
• Designed for lightweight high performance RC Gliders

KST X10 High voltage Softstart wing Servo - 11Kg.cm 0.10s 28g 10mm

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. Please note the servo recommendation of the respective model manufacturer when selecting your servos.
