    In Mission Planner under Initial Setup, Optional, did you go to the Test Motor tab and confirm that all four motors work and are spinning the correct direction (you can do this without the radio/Tx)?

    Once that is done, try to spin the motors under Radio control.  Arm. Throttle up (without props).  Go to Mission Planner Flight Data tab to see what errors are being generated while trying to arm.

    Try doing first rc calibration and then ESC with same saved rc channel's min max values. It should work
