Pixhawk 3 functionality w/ ArduPilot?

Two questions:

  1. Does the Pixhawk 3 work with ArduCopter firmware yet?

  2. If it can’t use ArduCopter firmware, can it still be used with Mission Planner? Or does it only work with Q Ground Control?

Yes the Pixhawk 3 works with Ardupilot Firmware. I advise you to use QGC.

Ok, thanks.

Also, is this the correct setup for your XXL GPS?
Or should the GPS base unit have it’s own telemetry radio?
