That was a fine demonstration, Mark. FF is great. Stir in some D min (AKA "D max"), balance the D min gain to hit D max a hair before the sticks (setpoints) hit their stops on your quickest snaps, and the quad becomes telepathic without overshooting. If anyone's listening ;-) it might be helpful to have the option to set separate D min gains for the roll and pitch axes... Thank you, as always, to all the BF Dev's.

Great video as always.

Thanks for explaining FF so clearly!

Great information. I will apply this to my 7” build. I’ve turned off feed forward to stay smooth, I will give rc expo and raise my feed forward

Awesome tips, Mark! 😃 Thanks a lot!!! Stay safe there with your family! 🖖😊

great video

@ 8:05 "cinematic and freestyle should love it too" - I agree. I think the most confusing part of feed forward, is the "transition" setting. When I was just beginning to fly I had several instances trying to do a yaw spin, where my quad suddenly yawed way more than I wanted it too, and I panicked, and wound up crashing (flying LOS). I didn't understand why that happened, I thought it was a desync that caused me to lose control, but I eventually figured out that it was the FF kicking in when I got too aggressive on the stick, and suddenly I understood WHY I heard the quad speed up so much and I had a "lightbulb" moment. For a while, I flew with FF amount set to 0 on all 3 axis. As I learned a little more, I eventually added FF but the "transition" setting is what activates the FF amount and ultimately, that is what needed adjusting. A transition amount of 25 - 30% (0.25 - 0.30) is a good trigger value for me. For beginners, I don't even think that FF is even necessary. Thanks UAV Tech! Another awesome upload!

I'm doing cinematic and love FF. It also sharpens my reflexes if I screw up and need to get out of the situations and as you said... in smooth flying it's not really noticeable - running an expo of .55 now for that :)

Thanks Mark!

Thank you!

Excellent

Such a brilliant man🤘🤘❤️❤️👍👍✊✊

Thank you for that clear explanation. Helped me a lot I'm tuning a new build using 4.3 I'm using nightly BtfConf 10.8_4137 and Betaflight 4.3 build #2537 So far so good (even very good), but I don't know what would be the best way to work. Just go pretty much for the last build or try to understand if I should be concerned with the last merge, m aking a new build ? BTW what build are you v for this vidéo ? And last, I noticed some "interface behaviour" surprising to me, for example in copy paste some groups of commands in the CLI. Some time it take all of them, some time only part of them but after few trials all of them (without modifing the commands). I'm not sure if it's kind of bugs or any other trouble non specially BTF specific (USB com ...)nd experimentations Should I try to report somewhere, or better leaving the DEV make their great job, which will finally gave us a great BTF version. Many thanks for sharing your knowledge and experimentations

Great video. Thanks for sharing your knowledge. Quetion for you, should FF be adjusted on it own or should people use the slider instead to keep value with good combination of each PID setting?

its so tricky to talk about whats a persons best FF, its a bit like mouse accelration, you use somebody elses mouse and its super slow or superfast, but its not a huge deal, you get used to it in minutes. the problem i had with ''setpoint'' was it felt like it was telepathic, i would try a very sloppy roll and it would perform a snappy and smooth out roll which was not what my shaky thumbs input... actually was a bit alarming. i've used pretty lowish FF ever since.

Very interesting ! like always... where can i find the voice of your radio ?

What threshold does BF use to consider a "snap" move in order to enable FF? This is gold as always...

What do you think of sim ff settings? Enough indication to help you find your own preferences or understand the feeling of high vs low? Also, nice update to your logo 👍🏼

Okay, i fly 0 FF or EmuBoost/EBLimit. But I have tuned hard my rates especially in Emuflight. All those weights and so on. So my quad is smooth and accurate at stick centers and make my fast moves near end of stick move be axelerated, and adding some weights to the end of the movement to make my footage smoother. My setpoints and gyro are almost even, maybe have some delay on full deflection, but not so big to be uncomfortable. As i understand FF gives you the same but in a simplier way. Cos it use only gyro data and setpoint and not what you want it to behave?

Which log viewer are you using and / or what setting do I turn on in the betaflight blackbox explorer to get the craft example to move with the gyro?

What if you are flying with low rates with like a cinewhoop what would be a good FF starting point?

Does KISS have something like FF?

Has anyone noticed the 3d quad overlay sometimes doesn't really reflect the actual attitude of the quad according to the video, or is it just me?

One real misunderstanding of FF in betaflight is that bf doesnt have an actual FF and FF in bf doesnt act any faster than pterm does. If it were a real FF it would act before pterm, which it doesnt. FF happens when setpoint moves, which creates error the instant setpoint moves, which makes pterm kick in. FF and pterm act at the same exact time when you flick your stick.

1st :D
