Item Type: Motor Servo Tester Product Size: Approx. 49 x 43 x 25mm / 1.9 x 1.7 x 1in Material: Aluminum alloy Applicable Counterweight: Servo, motor, ESC Adjustment Mode: Manual, automatic, neutral Output Signal: 1.5ms 0.5ms Input: DC4.8-6.0V Output: 15mA(5.0) Torsion: 0.08kg/cm Speed: 0.12s/60 at 3.7V Signal: 900-2100uS Frequency: 50-330Hz Servo Function: 1. There are 3 modes to detect steering gear or ESC: Manual Mode: You can turn the potentiometer at different speeds to measure the response time Finding Neutral Point Mode: return the servo to the neutral point Automatic 2 Brush Mode: make the steering gear swing at the maximum angle of two-brush 2. Can connect 1-3 servos at the same time to test the synchronization and consistency of 1-3 servos 3. You can connect 1-3 ESCs at the same time, test and compare their response time 4. Can be connected to the 3 servos of the CCPM structure helicopter at the same time, using the neutral position and synchronization function to debug the helicopter and the steering gear selection 5. Can be connected to the servo on the fixed wing aircraft, and use the neutral position and other functions to install the steering wheel and debug the aircraft
