The Bantam Check Master II is a microprocessor controlled Servo Tester, Propeller and Helicopter Blade Tachometer, Temperature Sensor and Battery Voltage checker all in one. It uses a precision pulse generator to test any brand of servo by movement, deflections, neutral point and band width. It does not need a battery to operate the servo. It will also display the electric current required to operate the servo on screen. This is a very useful feature as it helps you chose an appropriate RX battery for your model by adding all the current load of the servos.
