Connect 1-3 ESCs: Support to connect 1‑3 ESCs at the same time, test and compare their response time separately.4. For CCPM Helicopter: Can be connected to the 3 servos of the CCPM helicopter, adjust the helicopter and select the servos through the neutral and synchronization functions.5. Aluminum Alloy Shell: The servo tester is made of excellent aluminum alloy material, which is corrosion resistant and after anodizing.How to Use:As shown in the figure below, basically mark the pins, control and indication parts on the servo tester. The pin corresponding to the S symbol has no effect here, so you can ignore it. The servos connected to the left can be divided into 3 groups of upper, middle and lower, which can test 3 servos at the same time.Connect the power from the single row of pins on the right, the three blue lights will light up at the same time, and then the light on the left will light up.
