that's old I still wonder what are the best tech available to have a camera/screen on this thing, with what latency.

  So far as I can tell _nobody_ flies FPV (first person view) with anything except regular analog video cameras and radios. I'm guessing that's at least partly for cost reasons, but mainly because you don't even need to ask the "what latency" question. Even though iPads/cellphones/OcculusRift have much better and higher resolution screens than most of the inexpensive hobby FPV gear around, the lag as you digitise/compress/decode real time video streams is both too long and too variable. Remember John Carmak's rant about being able to get packets to London quicker than he can get them onto his screen? Imagine trying to control a ~400mph toy plane when you aren't sure if you've got 15 or 200ms of latency at any time? That'd represent "seeing where you are" something between ~10 and 200 feet behind where the plane is right now.

    Thanks for referencing the John Carmak "rant". I missed this. anyone else interested. http://superuser.com/questions/419070/transatlantic-ping-faster-than-sending-a-pixel-to-the-screen http://superuser.com/questions/419070/transatlantic-ping-fas...

    aren't there uncompressed low latency solutions ?
