The Autotune for INAV is an amazing feature. You do not have to worry about PID tuning. Or guessing the correct rates. Autotune does everything for you. Especially, it estimates correct rates!
In this video I will show you in details on how to correctly perform Autotune procedure on an fixed-wing airplane with installed INAV.
Oh, and very important. Autotune tunes only rates (how fat airplane should rotate) and feed forward gains. Just like it supposed to! There is no need to tune P and I gains on a PID controller at all.
The procedure is:
- Take Off
- Switch to Acro
- Enable Autotune
- Fly
- Disable Autotune
- Land
- Disarm
- Save new rates and feed forward gains

Autotune is just plain magic. With Autotrim, Autolevel, and Autotune I can go from maiden to a great flying airplane in 1 pack. Thank you, Pawel and the rest of the INAV developers for the constant improvements and for helping so many of us enjoy this great hobby. One topic I have not heard discussed is the recommendation for the use of Stabilized Yaw vs. RC YAW. And if used how to Autotune for it (full rudder deflections?) with either a standard or v-tail configuration.

It's not magic. It's science. And math. A lot of math

@WinstonSmith1984 8 месяцев назад

Thanks, this is the second most useful feature of INAV. The first most useful feature still needs to be implemented by someone smart: bdirectional dshot, e.g. #8658 :) I suggest switching to a OSD panel that shows the PIDs: then one can see in real time if and by how much they are being changed during autotuning. One thing that confuses me a bit though is the use of rudder in INAV as it seems when using stabilized rudder in the mixer, that INAV tries to resist the natural yaw in banked turns. I just set it to the non-stabilized rudder input in the mixer.

@Videolinquency 8 месяцев назад

Thank you for making life easy! One question, though: Do we need to minimize partial inputs as long as we fly in autotune? Could gentle stick movements feed false data to the system or otherwise compromise the process? (Flying by nothing but full deflections for a minute or two can be rather demanding, even though it's great fun.)

@FPVUniversity 8 месяцев назад

No, you don't have to worry about small stick moves. Just fly

@senseisecurityschool9337 7 месяцев назад

Specifically, auto tune ignores anything less than 50% deflection. Above 50%, it will "learn" how much roll you get from 70%, 80%, 90%, or 100% deflection. No need to avoid anything.

@frankwarner7279 6 месяцев назад

I normally set up my wings for about 80/+% throttle which is where I like to fly freestyle. Should I autotune at 80% or stick with the recommended 50%?

@mhk1058 Месяц назад

Does iNAv stabilization not need gain control that you have with a traditional gyro (Hobbyeagle A3 for example) where you can adjust the stabilization gain on the fly?

@FPVUniversity Месяц назад

You can adjust gains on the fly with Adjustments framework

@grzegorzdrozdz6664 7 месяцев назад

Hey, got a question, I have 3m glider (with electric motor) and I set up this on INAV, how should I do this procedure when I fly glider normally without motor turn on? Also I would like to avoid doing barrel roll, this glider is kinda heavy and never dont this on this one, but if neccecery I can try from 300meters :D One more, how mode soaring is working?

@senseisecurityschool9337 7 месяцев назад

With default settings, auto tune will function with at least 50% stick deflection. So you can roll left, then quickly roll right, without doing a full aileron roll. Similarly for pitch - so long as you move that stick at least halfway to max. This may give you a run that works well for your type of aircraft. If you have an aerobatic plane you want to do rolls and loops with, you'll get a better tune with that type of aerobatic flying. If you're never going to do aerobatics, you may not need it tuned for full deflection. Tuned for up to 75% deflection may be just right for you.

@catmanfpv9213 3 месяца назад

Thank you, Pavel. I confirm that it's proven true. After autotune, my plane is as smooth as baby's butt. But i found that it automatically saved after disarmed on inav 7.

@andrewjamez 7 месяцев назад

you can do most of this pre test flight if you have a fair idea of what your control throws need to be to achieve your desired roll/pitch rates. Many designers publish these. After that you just need to set your desired roll/pitch rates (pro tip, the 180deg default roll rate wil not be enough for many autolauches where a large amount of torque roll exists with pusher motors.)Then set feed forward rate in acro mode so that you achieve around 80-90% control surface deflection to what you get in manual mode. Then you will have much more success with pusher wing type auto launches and much less heartache and use of offensive language... Happy flying

@tubamanandy2 7 месяцев назад

What an interesting reply, I'd love to know the rough control throws for many of the small ZOHD models to make maidens more successful - not sure where you find these. Also, really interesting point about the standard roll rate not being enough - would love to learn more about that

@andrewjamez 7 месяцев назад

I set roll rate to 360 always for small planes 1.2m or less. most of the altitude lost during an auto launch is while the aircraft is trying to recover from torque induced roll.

@tubamanandy2 7 месяцев назад

Do you do this so there are less failures in Autolaunch as I cant see many craft eg. Dolphin, Dart etc being capable of anywhere near this roll rate. Is it likely to cause any issues ? (I guess when Autotune is completed it will drop the figure substantially)@@andrewjamez

@andrewjamez 7 месяцев назад

@@tubamanandy2 360/roll isnt as fast as you think. You can try less, say 270. The main thing is to set the feed forward rates to match control movement in manual. If physical max roll rate cannot match what you set it to in inav then feed forward will go through the roof in autotune

@mr_batch 7 месяцев назад

Thanks for your Video! I asked a few Month ago in the Inav Fixwing Group on Discord how it is with the Autosaving. And the Answer from Darren was: it saves automaticly (same as Autotrim). Now, you said it otherwise. Please, enlighten me: What is the Deal now? 1. save by Hand (as you said) 2. Trust the Autosave after Disarm (like Darren said before) ?

@tubamanandy2 7 месяцев назад

I was also under the impression it also Autosaves although I always use stick commands just to be sure :)

@Rogue_FPV 7 месяцев назад

I have always been under the impresssion that only the Auto-Trim auto saves every 2 seconds or so, but the Auto-Tune needs a manual save, in case someone hits their switch by accident, or doesn’t like the result of the auto-tune be their previous settings

@mr_batch 7 месяцев назад

@@Rogue_FPV no sorry. After deactivating autotune, land and disarm in on the lower line in the OSD "settings save". That means, that the Autotune Resaults is saved. Thats what Darren said. But, the 2 second rule on autotrim is correct. Sure.

@swissfreek 7 месяцев назад

yeah I see "settings saved" when I disarm even if I don't send the stick command. But at the same time, there must be a way to NOT apply the autotune if you don't like how it went, and if it autosaves then there's no way to do that since the only way to void your autotune changes is to power cycle without saving after landing.

@mr_batch 7 месяцев назад

@@swissfreek that exact was my Question. And the Answer was: "Just auto tune again. It’s only rates and FF. So you would have to have done a terrible autotune to get it too bad to fly." In the earlier Versions of Inav you have to save your Tune by Hand, but now? Sorry Guys, i'm confused now... ;)
