Autotrim for Fixed Wing Airplanes - how to do it in INAV?

[@alcmann]

thanks for the upload. Realized I was running this incorrectly. "land with the autotrim mode still engaged " Thanks for the tutorial !

[@alainrac56]

I am a 72 retired captain and R/C modeler since the age of 10, I have been flying FPV for 15 years, but now, as it is a good challenge to train my old brain, I switch to INAV autopilot, digital video and open source R/C, not easy... hopefully, they are your videos showing how to sort it out, and I wouldn't have succeded without you! Most videos on youtube are in english, not my native language, but I love the way you speak, slowly and distinctly, so I get every word😁, thank you for this!

[@FPVUniversity]

Thank! And good luck

[@Videolinquency]

You guys are definitely on the right track. New INAV features tend to correspond amazingly well to my own list of wishes. Thank you for doing this!

[@spartan3299]

I think I started with INAV 1.6 with an Omnibus F3 on a Bonsi wing Then a Carbonbird Paris Sirus FC on a Bixler. I also converted a a HobbyKing SX-20, a Phantom 2 clone to INAV again with the omnibus f3 with many crashes trying to fly it aggressively. Every, well almost every new version of INAV have increased the fun, performance and safety of our craft. Thank you and all who contributed their time, talent and enthusiasm for our hobby, one of the best hobbies. Dad first saw RC planes in Japan, as a teen when his dad was Stationed there in 1952..I think.,and was hooked. He had me flying pulse rudder and a cox .02 at about age 7 but I was never comfortable enough to become proficient . After Apollo I was intrigued with remote control and especially telemetry on motor gliders with the early FrSky voltage and Baro modules. Then an article in QST, a Ham radio magazine had an article of a fellow using an ATV transmitter on a large nitro plane. I just couldn't stop thinking about one of those. But Dad’s best friend at our AMA RC club flew FPV and he provided me with the original Skyzone goggles when he upgraded to FatShark. Dad is still my spotter when there and enjoys “Taking a ride” in whatever I am FPVing, as long as he is sitting. Even the kind of traditional AMA club members are surprised with how FPV has been developed. In the last month I have been taking members for rides in my new 85mm Whoop, F405 FC with Baro, and the Whooplite by HDZero. They were amazed as I am.

[@tubamanandy2]

For me (and others in the chat) this video has created more questions than answers - mind you, Inav is stil awesome and every day is a learning day

[@sptrader6316]

I love the INAV 7 progress, it really helps new flyers. I look forward to INAV 8 in March.

[@supermadmotocrew]

INAV has a setting like "Continuously trim servos", as I know, it helps constantly fly in level

[@CaptainCandycorn]

Im looking at that setting right now wondering if I should enable it. I guess it doesnt hurt?

[@supermadmotocrew]

@@CaptainCandycorn I fly with this setting ON, didn’t notice anything weird)

[@lowriderfpv8440]

Thanks Mate, I believe INAV only continues to improve, I'm working on my third INAV build and I watch and review your videos all the time to help with my builds.

[@MrBornenjap]

Great breeze knowledge. Thank you very much 🎉

[@JanDaliba]

Can you please create a video describing differences between Auto trim, auto level or auto tune and full process of setup, what to do first and using these three modes to finish a build? Thanks :)

[@SuperVette05]

Definitely on the right track. Plane is flying great after auto trim.

[@ndcapper]

I updated from Inav 5 to 6.1. It flies better than ever. So happy with the way that Inav is moving. I have enough confidence now to maybe put it on a waypoint mission

[@springpilot]

What about continuously autotrim activated in the Configurator. I do prefer that variation. Thank you!

[@joemoffo9706]

Thank You. This is so much easier then in the past.

[@FPVUniversity]

You're welcome!

[@jojo42069]

continously trim servos on fixed wing is also great. Why didn't you mention this in the video?

[@Johnny-tc6tz]

Great video , I am new to Inav and i believe this video will help

[@adilsongoliveira]

Yes you are going awesomely in the right direction. I'm eagerly waiting for the VTOL support :)

[@FPVUniversity]

thanks!

[@k1nk0]

These informational videos are great! Keep them coming 🤙

[@jas-FPV]

Can you explain how autotrim goes together with board pitch alignment?

[@luisete7076]

Buen apunte para los que empezamos en el hobby. Un saludo desde España

[@FPVUniversity]

Yo no hable Espaniol. Gracias

[@VolodymyrMoon]

Like always, thank you fir your amazing work

[@chipsterflysome]

Can I just use "Continuously trim servos on Fixed Wing" on the configurator or should it be put on a switch as in the video?

[@danjensen9425]

Absolutely going in the direction I want

[@FPVUniversity]

thanks

[@MCsCreations]

Excellent information, Pawel! Thanks a bunch! 😃 About iNav, it's going better than Betaflight! 4.4 has too many bugs. 😬 Anyway, stay safe there with your family! 🖖😊

[@probante]

isn t this feature the same as enabling servo autorim on the configuration tab?

[@chrissofpv3017]

Looks like it!.. That's probably why you won't see Servo AUTOTRIM in the Modes Tab of INAV 6.0/.1 I'll make a comment as Pawel appears to be referring to older versions of INAV🫣🤭

[@chrissofpv3017]

Hi Pawel...Just checked 6.1.0 in Modes Tab. No "Servo Autotrim" in dropdowns.Looks like its now tucked into the Configuration Tab as "Continuously Trim Servo On Fixed Wing" I assume your vid focuses on older Inav versions,yes?

[@DM4DS]

Disable continues trim in config tab to get the feature in modes tab

[@EnglishTurbines]

Pleased you did this video about it...I shall be using Autotrim on a switch in future...😮😮😮😳😏😏👍👍🇬🇧

[@Migueldeservantes]

That is awesome!! thank you much!

[@RenatoSchiavetti]

Hello, congratulations on the content! I have a small doubt, when I flew without a flight controller, on the first flight of each model I always had to trim the servo manually using the radio trims, but now using an FC and enabling the option "continuously trim servos on Fixed wing" do I still have to do this manual trimming to help the FC or should I fly without any radio trimming and let the FC take care of it? If the work is all done by FC, does it automatically save the parameters for each flight? Thank you very much in advance!

[@charliekg6600]

In INAV 6.0, there's a mode selection "auto level". Is this function the same as "auto trim"? There is no auto trim selection in INAV 6.0.

[@chrissofpv3017]

TRUE!.. I'm trying to do this. In 6.1.1 .NOTHING in the Modes Tab saying "Servo AUTOTRIM"... very strange😂

[@fordboyzzzz]

theres a autotrim tick box in inav now - do we need to do this first for the tick box version in inav settings?

[@dirtydogfpv6905]

is it just the disarm that saves it or dus it have to land as well

[@swissfreek]

And if you want to be really persnickety, you can mechanically recenter your control surfaces based on the adjusted trims, and then reset the servo center points to 1500, and run another auto trim just to fine-tune. The closer you are to mechanical center on your servos, the better flying results you will have.

[@TheSnow520lee]

hi Pawel, is there any chance to disarm mid-flight and then rearm, just to avoid landing for saving the auto trim calibration?

[@ebg4614]

Great tutorial. Short and to the point 👌🏼. What is that flying wing you've got in the background 😍?

[@JeffDoesThis]

Should I use the Servo Autotrim mode or Continuously Trim Servo function in INAV 6.0? Pros and Cons. Awesome videos by the way!

[@FPVUniversity]

I only use Servo Autotrim. But that is my preference

[@BBFPV]

This is for manu? In Acro and autoflight modes there is no difference?

[@aerografixs]

Inav is most definitely on the right track, keep up the good work on one of my airplane, I fly with Inav FC but I don't fly FPV with it so I don't arm or disarm , so my question is since it is not armed, will I be able to save the auto trim anyway , Thanks for the great work you are doing

[@snowhack8903]

Can't wait to try this. The only complaint I have is probably not on you. There is no wav file for autotrim or servo trim in the edgetx sound packs. That I could find anyway. I ended up making my own with an old copy of OpenTX Speaker. My only suggestion so far is please create an INav specific sound pack. In fact, could you do one in your voice? That would be epic!!

[@uavtech]

How long after enabling is it tracking servo center points?

[@FPVUniversity]

atm it's 2 seconds

[@uavtech]

@@FPVUniversity thankyou, that is what always confused me in the past. Would be neat if OSD showed something during sampling time, but not critical.

[@rodeopilot7495]

I'm little confused . so on this video you suggest to have the servo auto trim as a mode, but there's an option on the configurator to have the servos auto trim continuously . what's the difference? and what are the advantages and disadvantages of both ?

[@jotham123]

on arduplane I leave it on all the time as it's just an option that you turn on. I find after lots of hard maneuvering the trims can be out a little but they readjust themselves within seconds. Leaving it on really helps on a plank in which I have several sizes of battery pack or if I slightly misplace it. Saving the trim and putting a marker in the fuse for perfect battery placement each time is probably a much better idea.

[@FPVUniversity]

They are different things and work in a slighly different way

[@rodeopilot7495]

ok. do you recommend one in specific for a long range plane ? @@FPVUniversity

[@FlyWithMohsin-Indian]

what if we keep On function i.e continuous servo trimming on for fixed wing and not using as flight mode?? will it make difference?? or it will trim servos or try to trim servos every time I fly and save that setting when I land .

[@swissfreek]

It will always adjust the trims and save when you land. This is how I prefer to fly. Not sure if there’s an advantage to having it on a switch other than you have explicit control of when it’s active.

[@spartan3299]

Should we do the Auto trim if we select Continuously trim servos on Fixed Wing?

[@FPVUniversity]

Nope

[@mhk1058]

I read somewhere else that this should be done in manual mode - which sort of makes sense so it’s trimmed without any other input. Can this be done or should it be acro?

[@BlindedByEvil]

Nice saves everyone trying to use save function. Is this in inav7 or later versions?

[@scottyh72]

I don't like continuous servo autotrim. It trims servos as I slow down to land, so my trim is all messed up for the next launch. I use servo auto trim on a switch at a nice fast cruise, and let the I term trim for higher and slower speeds.

[@FPVUniversity]

I'm also not the biggest fan of the contonous method. It's just an additional integrator that can wind up

[@EnglishTurbines]

​​@@FPVUniversityGlad I read the comments. This exact same problem reared its very ugly head the last time I flew during launch!!! I will be putting it on a switch myself now for the exact same reason....😮😮😮😮👍👍👍🇬🇧

[@nickboul3328]

Can you e please it a little more?

[@FreeEditsForYou]

So put it on a switch for basically a "tuneup" versus having it on the entire time? That's what it seems like

[@vavanetsp]

Can I use this method with my Vtol? How will be work in this case?

[@FPVUniversity]

yes, autotune in airplane configuration will work

[@danjensen9425]

Awesome thank you

[@YT-qp3xw]

Hello sir...im lil bit confused...what i see from inav 6.1.1, thre is no autotrim except im ENABLED continuously servo trim on Configuration..i enable AutoLevel in Stabilized mode and Autotune on Acro mode...is that correct, yes?

[@EnglishTurbines]

I'm confused in exactly the same way....😮😮😮😳🤔

[@FPVUniversity]

Continous Servo Trim is something else than described in this video. If you use Continous, manual Autotrim is disabled. This in intentional

[@EnglishTurbines]

@@FPVUniversity Ah...!....but...do we still have to land disarm and save..??...😮😮🙄😏🇬🇧

[@YT-qp3xw]

i did not see the auto trim mode to set it up in inav 6.1.1, done autolevel on angle mode and autotune on acro mode during maiden, in continous trim servo enable...is that the right way?...or...do i have to Disable the continous trim servo then the autotrim will appear in mode tabs?

[@YT-qp3xw]

well...i found it...thanx buddy...much obliged

[@АртёмВорохобин]

HI! What you think about dedicating one channel for all switches? All radios today is sending digital signal over the air, and it's resource vasting to use values from 0 to 1000 to encode single bit (if there is 2-position switch). At now i combinig 2 switches to single channel by selecting distinct ranges for modes (for example: for couple of 2-position switches it can be first half of range for switch1 "on", and second for swith1 "off". For switch2 there 2 ranges for "on" - first half of "halves", and two ranges for "off" - second halves). So it works flawlessly, but takes a lot of effort to tune

[@wtfmimshag]

Does INAV only auto trim outputs which have pitch/roll/yaw controls mixed? Or will it also attempt to trim a pan/tilt servo (e.g. RC passthrough channels)?

[@FPVUniversity]

Only control surfaces

[@wtfmimshag]

@@FPVUniversity thank you!

[@DontEverGrowUp]

INAV can display the current mAh/mile rate in the OSD, but I would like to see the overall average mAh/mile since the flight began, instead of having to wait for the stats at the end of a flight to see a value after the fact. Also, I think I heard that v7 will have a value for the total distance travelled (not just distance from home) during a flight, so that's another value I'd like to see.

[@micsherwood4930]

I'm on INAV 7.0, so is "Auto Level" the new name for this "AutoTrim"? Also, to save settings, I don't have to use a stick command?

[@Jan-cm2ye]

Im also confused if the "auto level trim" mode can be used as an alternative for the "servo autotrim", or if both should be done.

[@zoltantoth5177]

Thanks for all that is INAV. Definitly heading in the right direction! Presumably, if I had used my Tx trims to get the aircraft flying straight and level prior to carrying out the Autotrim procedure, I should recenter the Tx trims before the next flight. Is this correct?

[@FPVUniversity]

Yes, you should not be using trims on radio when flying with a flight controller. FC (INAV, Ardu) should take care of the trim, not radio

[@zoltantoth5177]

Thanks@@FPVUniversity. Does the Autotrim feature automatically level the aircraft prior to recording the offsets required to do so, or, do I need to level the aircraft myself with the sticks whilst Autotrim is engaged?

[@helmuthuneke1775]

Thanks for the last 2 videos, a question I have is about permanent enable airmode I fly airplanes and understand from my quads airmode = acro?? i have it permanently enabled. Thanks l❤ looking forward to inav 7

[@FPVUniversity]

Airmode should be always enabled just like it is enable for everything by default

Thank you for this video ! What is the best way to final tune an airplane: Autotune first and then Autotrim, or the other way around ?

first autorim, then autotune

What to do FIRST? Auto TRIM or Auto TUNE
