This tool takes a .bin log and performs a "MAGFit inflight calibration". Calibration parameters are found that fit the measured magnetic field from the log to the expected field from the World Magnetic Model.
For best results use a flight log that covers as many orientations as possible. Flying figure of eight patterns works well. If you need a motor calibration using either throttle or a current reading then you should also cover as wide a range of throttles and current draws as possible. You do not have to be in any particular flight mode.
