If you purchase a DJI smart controller and goggles will they work with all DJI drones. Also can you save money when buying other DJI drones without the controller and just purchase drone and extra batteries?

Hi there. Thank you for reaching out. The DJI Smart Controller is not compatible with all the DJI drones also for the Goggles, the old version like the DJI Goggles and DJI Goggles RE only works with Spark, Mavic Pro, Mavic 2 series, Phantom 4 Series, and Inspire 2 while the DJI Goggles FPV only works with DJI FPV. Hope this helps. Thank you for your support!
