Wow what a difference... Just with the PT1.

The # worked

Hello, a newbie here (first sorry for my english, not my native language)

today i tried removing the filters on my quad. i was able to set it to PT1 and remove filter 1, when i removed the 2nd filter some of my motors started getting hot so i reversed and just stayed with filter 1 removed. my question is:

what happen when for example i hit a flag or a gate with quad during a race and keep flying with a bent prop or something else introducing vibrations to the quad in that moment? what i mean is if some people are not able to remove filtering because they have a noisy setup, what happends when a setup becomes noisy with that filtering already removed, is there any risk?

hope i was able to express my logic in an understandable way, thanks in advance.

Welcoime to IntoFPV hailenp! Also a great question, I hadn't considered it before but now am curious too.

Im curious about this now also

In short: all hell can break loose yes the risk is real - stuff might run hot quickly if filter settings are on the edge and you happen to bend or break a prop mid-flight.

The dterm filter settings depend on profile - you could make a second profile for example with a wider dterm notch and lower lowpass frequency (and maybe lower PID), so you could change profile quickly to continue.

I might do that and then tie it into my airmode switch... at the point where I have a busted prop but am managing to still fly I don't want to be doing the kinds of things I need airmode anyway... even if rigth now my quads always have airmode enabled lol.

Yeah, as i'm not a racer, at that point i usually "fly home" or just land/drop it somewhere safe, like when vibrations are so bad it hardly stays in the air and hardly can see anything... last time this happened i was missing 1 blade on my 2-blade props lol

But sadly you can't change profile by switch (yet), only by stick commands while disarmed. It was announced for betaflight 3.2 a while ago though.

you can't?

I was under the impression by one of the guys I fly with that you can. I might have to figure out what he's been doing and I'll have a look this afternoon to see if I can figure it out. Perhaps they're using 3.2 or something, I don't know

In the officially released versions so far you can change rate profiles  by switches but not profiles. Maybe that's what he meant?

Ah, yes... that's it... I just automatically assumed if you could change rate profiles that you'd be able to change pid profiles too...
