Feature: 1. Can test analog and digital steering gears, control the motor for stepless speed regulation test, and test whether three steering gears are synchronized at the same time (this function is mainly suitable for helicopter steering gear in CCPM mode) 2. There are three modes to detect steering gear or ESC (motor stepless speed control test), manual mode, you can turn the potentiometer at different speeds to measure the response time, and turn the knob to check the response speed of the steering gear 3. You can connect 1‑3 steering gears at the same time to test the synchronization and consistency of the steering gears; you can connect 1‑3 ESCs at the same time, test and compare their respective response times, test the maximum angle of the steering gear and swing back and forth 4. Can connect 3 steering gears of a helicopter with a CCPM structure at the same time, and use the neutral point and synchronization function to debug the helicopter and select the steering gear. 5. Can be connected to the steering gear on the fixed‑wing aircraft, and use the neutral point and other functions to install the steering wheel and debug the aircraft 6. The product is lightweight and easy to carry, the weight of 27g will not increase your load‑bearing capacity Specification: Item Type: CCPM Servo Consistency Master Shell Material: All aluminum alloy shell Input Voltage: DC 4.8-6V Size: Approx. 48 x 42 x 17mm / 1.9 x 1.7 x 0.7in Weight: 27 g / 1 oz(approx.)
