Converting from Betaflight to INAV - Special considerations

Comments

Jonathan Oei Joeng

Hi, i know this is old thread but now INAV already version 7. Is there any different now? If I want to tune the PID, can I use basement tuning process? I know INAV doesnot have slider but I think I can increase each value manually. What do you think?

Nice to hear your thoughts on iNav...Pawel put me on mute in discord when I said the Unicorn should be turned off....didn't get the best reception either lol...I kind of respect the simplification they made on the filter setup tho...

....I didn't realise they had another LPF on there good spot! I expect they are using the BF LPF2 in the same way that BF does - it goes between the 8k gyro and the pid loop. It has anti aliasing uses to smooth any issues with the downsampling...ABG filter and smith predictor are from Emu...questionable what it does...ABG filter default off tells you something IMO...

Interesting video ! Lots of valuable information about filtering and pids. Great work, defiantly want to see more content like this one. I did some tests on INAV on 5 inch quads whith purpose to install it later on cinelifters . Position hold and RTH worked really good but I got confused by pids and filter settings. Didn't want to risk with something that I'm not confident with. After watching your video I could actually try give it a second chance but do you think is reliable ? compare to betaflight.

yes, roughly speaking INAV PID = BF PID x [0.71 1.0 0.66], but you'd want to set INAV TPA ~= 0.3 or more depending on where in the tuning window your BF rig is tuned.
