Features: <br>Fully aluminum alloy enclosure, anodized, can test analog and digital servos, can control ESC (motor stepless speed regulation test) <br>It can simultaneously test whether 3 servos are synchronized (this function is mainly applicable to helicopter steering gear in CCPM mode) <br>There are 3 modes to check servos or ESC: <br>Manual mode: turn the knob with different speed, check the reaction time; <br>Neutral mode: make the servo go back to the neutral point; <br>Automatic "window wiper" mode: make the servo swing like a window wipers in the biggest angle. <br>It can connect 1-3 servos simultaneously and test such as 1-3 servos consistency and so on. <br>You can also connect 1-3 ESC to test and compare their reaction time respectively. <br>It can connect 3 servos of the CCPM helicopters, and select servos by neutral and synchronous functions <br>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. <br> <br>Specification: <br>Material: aluminum alloy <br>Input voltage: DC4.8-6v <br>Channel: 3CH <br>Weight: Approx.28g/1oz <br> <br>Package list: <br>1 x 3CH ESC Servo Tester <br>1、Fully aluminum alloy enclosure, anodized, can test analog and digital servos, can control ESC (motor stepless speed regulation test) <br>2、It can simultaneously test whether 3 servos are synchronized (this function is mainly applicable to helicopter steering gear in CCPM mode) <br>3、There are 3 modes to check servos or ESC <br>4、It can connect 1-3 servos simultaneously and test such as 1-3 servos consistency and so on. <br>5、You can also connect 1-3 ESC to test and compare their reaction time respectively.
