That can mean so many different things to so many different people. You sound like you belong in the AV forum. FPV is take what your dealt. I don't drive all that way to find 10mph winds and go home. I've flown in 30 mph winds like it was another day. it's not fun and at that point i consider it not useable. if you watch some of those zephyr videos on my channel alot of em are pretty stable, but not zenmeuse stable.
A 59" or even 81" wing aint really an AP tool as in clean fast low video, but you take it up 50' like you see in my other vids (sometimes) hate flying more than head high,,,,,,, it is super stable
heres a few off the wing....... the big thing with all the tools in video making is you get clips, small short segments that are perfect in every video, but in fpv bragging as this thread is, that's not as fun as bigger chunks showing miles of coverage.
my zii with eagle trees guardian is the most stable one in my fixed wing fleet now but it's also fine tuned. The rest of these i'm showing in the video above are flight #6 of it's life, and it had a bouncing problem, the second and third clip of that film above is a zii and it's pretty stable for 10-15mph wind
disco
The smooth factor between a small handi cam/gopro and a nex5 kinda IOS lens is night and day. I'm doing a wing and octo to fly fast with it, but am easing my feet into the water and there not totaly tuned, ready yet.
