If you want to have a great flying airplane, you have to tune it. Both rates and PID controllers. Luckily, in INAV it’s a super simple process that takes only a few minutes and can be done with only one LiPo battery. In this video let’s take a look at all the elements of the tuning process:
Hardware setup
Reflex
Center of Gravity
Autotrim
Autotune
Final updates I like to make to all my airplanes
And, like always, happy flying!

Yayyy another tuning video, i’ve been trying for months and months now to help people on fb with understanding pid tuning and other settings, i’m glad to see someone else releasing information on how to do it propperly, especially one of my fave youtubers on my favourite firmware ;) 🎉

I have to ask Pavel, is there a reason to have auto trim on a switch rather than have it always enabled? Will this change the tuning process?

Me three! I have this turned on all this time, as suggested by Painless360... Should we be doing this, or avoiding the practice, for the best flying plane?

@senseisecurityschool9337 2 месяца назад

That *is* a great question. Two related advantages come to my mind. First, the trim will be consistent on every flight. This helps make the plane more predictable - it will fly the same today as it did yesterday. A related advantage is that I can check the trim and make sure it's good. That it's trimmed *right*. Once it's good, with the switch off it won't change (and therefore can't get messed up). On the other hand, continuous auto-trim WILL change the trim - and sometimes you want that. If you switch between different sized batteries, the battery is installed in a slightly different position, or you add some accessory the trim needs to change. Continuous auto-trim will automatically take care of that. On a racer, I would want consistent, predictable performance - so I wouldn't want continuous auto-trim. On a experimental plane on which I'm changing things around, I might want continuous auto-trim to keep updating the trim as I change things around.

Thanks. I heard nothing about yaw in the autotune procedure. What should we do to get the best yaw tune for planes with a rudder? Fly alternating wings level circles?

@alainrac56 2 месяца назад

Thanks for your great assistance for beginners! I didn't understand well how to use the autotrim, when flying acro, do you have to push or pull the stick to maintain the altitude before to switch autotrim then wait 2 seconds and release the stick? what is the proper sequence? I am also confused with acro mode, as it is not supposed to act on pitch axis to maintain altitude...when I first trim a new model to fly strait on manual mode, then switch to acro mode, then, the model pitch down...what did I miss?

Airport is in the works

@jaysonrees738 3 месяца назад

This is good information. Thank you for working hard to educate. A bit of opinionated feedback. Not enjoying the quick changing text trend that's going around. If you're set on using it, by all means, but I'll probably go audio only in that case.

@BrainDeadEngineering 29 дней назад

Great Intel ! In INAV 7.x I believe disarm will auto saves setting now ? I do see in OSD a flag...saving settings . True ?

@blueskyfpv 2 месяца назад

Great explanation as always: thank you. Is it necessary to land and save after the auto-trim, or can you do the Auto-Tune on the same flight and then save?

@FPVUniversity 2 месяца назад

It theory it is possible but I advise aginst that.

@blueskyfpv 2 месяца назад

@@FPVUniversity OK. Thanks for the clarification. I was also happy to learn that I don't need to focus too much on setting perfect elevon reflex when using a flight controller - one less thing to worry about.

@CaptainCandycorn 3 месяца назад

Thank you for this! I keep forgetting to run these two adaptations on my plane. One thing to note, is it preferred to do all this on a day with minimal wind?

Nice video ! Just one question … why do we need to manually save the settings for Autotune ? In my OSD i always see the “settings saved” message automatically after landing in the flight summary screen. (I have continuous trim aircraft setting on) Do i still need to manually save anything by stick commands ? Thx, Florin

@TheTuterTieuli Месяц назад

how much should i rise the I gains ?

@mr_batch 2 месяца назад

Good Job Pavel! Thx for that! One Question: You said, you DONT have to save the Autotrim, ist automatically. But, do i really have to save the Autotune manually? Really? Because, after Autotune and landing, the OSD said: "Settings saved" (same as Autotrim). Thanks, happy flyin! Axel

Pawel I have 3s motors in my quadcopter but I want to fly with 4s battery. Any details how to tune this in INAV ( no in radio) ? I know this is posible in betaflight but i prefer INAV ://

@dabit4840 3 месяца назад

Does autotune also work with continuous servo trim enabled? I tried autotuning once but even after stick command after landing the pids were unchanged so I did a manual tune.

@FPVUniversity 3 месяца назад

both are separate things and solve different problems. So yes, they can work together

@rgglenn150 3 месяца назад

Can you use quad fpv flight controller for fixed wing? I have a f7 aio

@adilsongoliveira 3 месяца назад

Sure. It may be slightly harder to wire but there's no issues with that.

@FPVUniversity 3 месяца назад

Depends on FC. It has to be able to drive motors and servos on available outputs. Not all can

@blueskyfpv 2 месяца назад

Many can, but you need to check to be sure. As long as the motor outputs can be changed to output servo signals it should work. Check to see if there is a target for your board available in INAV or for information on the manufacturer's website.

@domgoff999 2 месяца назад

You say autotune will determine the correct PID's and the rates. I thought PID's are no longer tuned just rates and feedforward?

@FPVUniversity 2 месяца назад

Let's say it's a simplification as it sets default P and I gains and then determines FF (part of PID process) and rates

@@FPVUniversity Yes I know, I have seen it. BUT you released the video auto tune first, 5 months ago, and then autotrim, 4 months ago. And under this video you added auto tune first and then autotrim. That got me thinking...

@stevep4131 2 месяца назад

I have to say I'm wary about the iNav I term. I keep it at zero and just use P with a touch of D. In other words I go completely against the advice of this video. I fly scale. My planes have wheels and they take off and land on the ground. I sometimes get the impression this is very rare among iNav users. I'm concerned that the I term can get into a "wind-up" problem -- I mean where it attempts to correct for (typically) pitch while the plane is sat on the ground. The elevator control can end up at maximum travel and will take time to return to mid position. In my opinion this could cause a crash the moment the plane leaves the ground. Am I wrong? Always open to advice and ideas!
