Compact and lightweight, it replaces bulky remote controls with a simple knob interface, enabling quick, accurate servo diagnostics and motor speed control for hobbyists and professionals alike. ## Description Features: The device also can be used as a signal generator forelectric speed controller, then you can test your motor system without using a transmitter and receiver. There are 3 modes to check servos or Electronic Speed Controller: Manual mode: turn the knob with different speed, check the reaction time. Neutral mode: make the servo go back to the neutral point. Automatic "window wiper" mode: make the servo swing like a window wipers in the biggest angle. It can connect 1-3 servos simultaneously and test such as 1-3 servos consistency and so on. You can also connect 1-3 ESC to test and compare their reaction time respectively. It can connect 3 servos of the CCPM helicopters and select servos. It can also connect the servo of airplanes install the steering-box and adjust planes by using such as the neutral mode and so on. Features: Can be easily detected and set the dummy bit server, jitter and median. - Can be connected to two servos or ESC; MCU control, good stability, high accuracy. Turn the knob, steering can be detected. If you connect the electronic governor (brush or brushless available), you can get rid of the remote control device for manual control, for testing tone. Speed ​​or motor performance is very practical, no longer cumbersome connecting the remote control and the receiver. It is equivalent to a "Hand Dynamic Receiver "feature, playing rudder knob analog transmitters. Specification: 1. Output: ≤ 15mA (5.0) 2. Input: DC 4.2-6.0v 3. Output signal: 1.5ms ± 0.5ms 4. Dimensions: 35.2 x 31.5 x 14.8mm 5. Weight: 7g 6. Adjustment method: manual, automatic, neutral. Package includes: 2X RC Servo Tester 3CH 4.2-6V Digital Multi Servo Tester ECS Consistency Speed Controller Checker Adjustment Steering Gear Tester Review: Excellent quality - I have a million servos laying around and needed to test them. This servo tester worked perfectly and allowed me to figure out which servos were good as well as their sensitivity. I am very happy with this and the price. Review: Mostly OK, prone to resetting on larger servos - This tester seems to work fine for small servos. With a larger one, rapid movements tend to cause it to reset and hang for a moment, even with the servo unloaded. ## Features - 【Specification】Input:DC4.2-6.0V; Output:≤ 15mA (5.0); Output signal:1.5ms±0.5ms; Dimensions: 35.2 x 31.5 x 14.8mm. - 【can be used as a signal generator】The device also can be used as a signal generator for electric speed controller (ESC).With the multi servo tester, you can test your motor system without using a transmitter and receiver. - 【3 Modes to Check Servos or ESC 】1.Manual mode: turn the knob to view the servo response speed; 2.Neutral mode: making the servo go back to the neutral point; 3.Automatic "wiper" mode: making the servo swing at the biggest angle.the ability to easily detect and configure the server's virtual spaces, jitter and median.It can connect 3 servos of the CCPM helicopters and select servos. - 【manual speed control】If you connect the electronic governor (with or without brush), you can get rid of the remote control device for manual speed control. - 【Very practical】It is very practical to test the governor or motor performance, no need to tediously connect the remote control and receiver.It is equivalent to a "manual receiver" function that simulates the transmitter steering through a knob. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CYZ6WVWP | | Best Sellers Rank | #311,290 in Toys & Games ( See Top 100 in Toys & Games ) #708 in RC Servos | | Date First Available | March 25, 2024 | | Item Weight | 0.705 ounces | | Manufacturer | Ferwooh | | Package Dimensions | 3.15 x 2.36 x 0.39 inches | ## Images ![2PCS Simple RC Servo Tester 3CH 4.8-6V Digital Multi Servo Tester ECS Consistency Speed Controller Checker Adjustment Steering Gear Tester - Image 1](https://m.media-amazon.com/images/I/61Q5SFJL+CL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent quality *by N***. on April 15, 2024* I have a million servos laying around and needed to test them.
