Checked out FieldAgent today. Looks good. But I'm not willing to pay $ 5.00+ a month for just the flight software. Most flight software is free or you pay for it just one time like AutoPilot. Too bad, I would have liked to tried it.
Good question, I think at 200m (or 300 yards) you don't really see the drone anymore. As soon as you check the telemetry, you can't find it visually again. At 120m height and 300m distance is a very small point and that without taking into account the sun that often does not let you see at smaller distances. They are supposed to be VLOS flights but in practice I trusted in telemetry more. I do a preliminary study of the obstacles and depending on the height of the highest, I know the minimum height at which I fly safely.I am familiar with Parrot, but most of the ones I know of are like the eBee, very expensive. The other thing that concerns me is the BLOS issue. I don't know about you, but with my eyes, about 1200 yards is max for me. If you are flying 500 acres, thats over 1870 yards long. How do you comply with FAA rules if this is the case? The issue then becomes not how far you can fly, but how far you can see. I'm I missing something?
