There is quite a bit of open source info out there on how to build these things these days. I think the quadcopter/'drone' boom kinda opened up the market for rc hobbies in general. I've seen guys with UHF fpv setups on planes fly for miles and miles and maintain signal. With purpose built antennas they can go even further. The legality is .. suspect at best, but shrug.
yeah, fair enough. we had to build virtually all of the software from scratch, including like, IPC. i wasn't involved as much with hardware but it does seem to be much more out there these days.
