I have a second receiver and can show on secondary screen like tv or jumbotron.
What are you using for your fpv gear. I bought a Fatshark setup a while ago, but haven't put it on anything. I'd like to use it on a flying wing, but a quad certainly would make it easier, or least easier to stay range as it's not trucking along at 100mph.
If you do a quad go big heavy and with torquey props instead of going for speed. I've got an Armattan quad that is fast and nimble but would suck for FPV.
