Matrice 300

Since the Matrice 300 has to use DJI Pilot, how could I incorporate Pix4D?

Hi Robert,
PIX4D is drone agnostic so we can work with any piece of hardware. In your case you can fly the M300 with DJI Pilot (or any supported flight app) and once you land simply remove the SD card and import the images into your PIX4D software. It is a fairly simple workflow.
