I'm not Ancapistani but I think iNav is more suited to that sort of thing, over Betaflight. I don't have any experience with it personally though. Also check out OpenHD. It's a 100% open source HD/Digital FPV system with unconventional use of Wifi (I think it's monitor mode or something?). It's not typically used for FPV because of the high latency and time to reacquire after signal loss. But if you're going autonomo…

I see, checked those out in the past and I'll take another look. Question was more regarding hardware though, but it's ok if you can't answer.

Uh… I accidentally wrote you a novel :)

Shoot me an email at my pseudonymous address with your preferred means of contact, and I’d be happy to chat. I try to keep this HN account not easily connected to my “root identity”, but I don’t mind connecting directly with individuals.

I use iNav for my wings, but just don’t have the urge to deal with it in FPV quads. Between the added weight of the GPS module, the limited options for flight controllers that support iNav and have an onboard barometer, and the overall lack of focus in iNav for that sort of use case I just find Betaflight to be a better fit.

That makes sense. Btw, the horizon drift in INAV was a significant reliability issue for me. I switched to AP now, and it's leagues ahead in terms of reliability and features.

I wish I could remember what it was, but I saw a few weeks ago that someone had released a new FC that included onboard GPS, dual barometers, and some other “thing” that they were marketing as fixing iNav horizon drift. If I come across that link I’ll post it. At any rate, it seems to have been getting improved with each version.

I haven’t been using iNav in a way where it’s an issue - my wings are mostly just for recreational FPV, and the big features for me are autotune, altitude hold, position hold, and RTH. Between those, I’m able to get a wing flying stable very quickly and am able to fly further away without worrying about RXLOSS meaning that I have to chase the thing down across three counties.

Hm, I'm very dubious that any hardware can fix INAV's horizon drift, which is due to the bad AHRS implementation. The problem I had was that I couldn't trust RTH (and I know people whose wing has crashed during RTH), because whenever I switched to RTH INAV would dive for several tens of meters before actually coming back.

I had a few close calls where it almost crashed into various objects while circling to RTH, and I decided I didn't want to lose a wing (or, worse, falling on someone's head), so I switched.

I’m not interested in FPV/goggles, just aerial photography. Looks like one of the cheaper DJIs probably makes more sense for me.

Ah, for sure. In that case, I recommend the DJI Mini2 if you’re going with new. If you want to save a few bucks, the DJI Mavic Mini “Fly More kit” can be had for ~$300 used. It includes three batteries, a charging bank, and everything you need except a cellphone to use for a screen. I took this with a Mavic Mini when I was just getting started with it: https://youtu.be/-uZYxg8FmY8

Very nice, thanks.

for DSLR that doesn’t have gyro, can i just put a gopro on top of it and stabilize both out of the gyro data from the gopro?

Actually found a video of someone on youtube doing exactly this. I will need to try it myself this is awesome!
