I wonder what they're using as a flight controller? Is it linked to the ground (via cellular or similar) during the whole flight? Or autonomous for part of it?

I wonder what they're using as a flight controller? Is it linked to the ground (via cellular or similar) during the whole flight? Or autonomous for part of it? EDIT: Looks like their ARTF electric version uses the Ardupilot CUAV V2+ - https://ardupilot.org/copter/docs/common-cuav-v5plus-overview.html https://ardupilot.org/copter/docs/common-cuav-v5plus-overvie... I can't find any information on the data link, that they call: "Sprintlink Pro Data link & Video Link". So not sure if this uses cellular networks, or something else during flight. Hybrid products definitely exist: https://www.skyhopper.biz/products/communication-data-links-combo/ https://www.skyhopper.biz/products/communication-data-links-... EDIT 2: The ARTF version is wild. For under $20K - you can just buy a drone that can deliver a 3kg package (6.6lbs) anywhere within about a 100 mile range. https://www.muginuav.com/product/mugin-ev350-full-electric-vtol-uav-arf/ https://www.muginuav.com/product/mugin-ev350-full-electric-v... Besides "last mile shipping" and smuggling implications, I'm trying to think of how this could be useful today. Maybe some kind of search and rescue where someone activates a personal locator beacon, and you could send them supplies before you could reach them? A little under a gallon of water? IDK, seems like a stretch. But I feel like there has to be more practical implications.
