First build advice needed(simple_

$500 for the drone alone, or along with everything else needed to fly?

And are you looking for something that's good for FPV or more closer to the way that the Mavics are flown?

4g/5g control is possible, but the latency is so bad that you cannot manually fly, it needs to be flown with some sort of autopilot capability

Those are also not the smallest devices in the world of FPV, it won't fit cleanly on something like a 5" quad
