If I'm flying and land more than about 150 feet away and cut the throttle off, my motors disarm and wont start. I have to get to within around 30 feet then I can rearm the motors and it works fine. I'm running a Spektrum satellite receiver with CC3D. Is this a setting in Libre Pilot or a failsafe in the Spektrum receiver?

If you can't arm from more than 30 feet away the signal must be too weak until you get that close.  It may be that the antenna placement on the quad is such that the range is greater in the air than sitting on the ground.
