SKYRC motor analyzer is a precision electronic device that is especially designed for measuring the KV value, RMP, current drawn, motor timing, vibration noise level and checking the function of hall effect sensors of a brushless motor. It comes with a 2X16 characters LCD that is able to display real time measuring value of either sensor or sensor-less brushless motor.
