DJI did it and introduced a digital FPV system that actually makes sense. There are goggle, radios, video transmitters and it not only works but also does not costs a fortune. Really, DJI Digital FPV is relatively cheap when you have 1 or 2 drones. When you have more, it gets problematic. Also, they do not show it, but where do you put it on a 5-inch drone? None of my frames would accept a camera and transmitter inside. So, DJI Digital FPV System is a huge step forward. But it's not there yet. Maybe the next generation will make more sense. And, do you know that FatShark is also working on a digital video transmission?
