Turnigy CCPM Servo Consistency Master is a very handy servo driver/tester that can test the consistency and set the centering for up to 3 servos simultaneously. This is great for anyone who is setting up RC airplane, car, or CCPM 3D helicopter and would like to see if their servos are actually working or compare the response time of each servo before installing them in your model. Additionally, you can set your servo into neutral/center mode without having a Transmitter/Receiver.
