Seen this a few times and am surprised it's actually a viable solution. Used to be heavily into fpv a long time ago and remember MIT(?) had autonomous CV software that could easily navigate through thick forests that was open sourced, I think the only real use of onboard GPS there was "go from point A to B"

This was perhaps a decade ago mind you, people rocking DIY setups had fairly limited computing compared to what you can buy today. The PID needed for quads/hex/octos to stay aloft has trivial compute requirements.
