Thanks for the clear explanation. Autotrim and autotune have always seemed too much like magic for me to attempt. Perhaps, between this and Painless360 I will get the courage to give it a try.

Auto trim is such a lifesaver compared to the old method of fly, fight the aircraft, land, adjust, fly again, still fighting the aircraft, oops adjusted in the wrong direction, now it’s worse, etc. I would still recommend that after auto trimming, now that you know what your servo centers are, if they are way off center, go back and adjust the mechanical linkages and then reset the auto trim. If you don’t do that, your servo “centers” could (theoretically, in a bad setup) be near the end of travel, and then weird things will happen when you try to input control movements. My point is don’t be lazy and have a horrible linkage setup and count on auto trim to fix it all for you.
@rnoma68983 жыл бұрын
Excellent. I would add that if you're burning fuel in the process, then pick a midpoint burn off to do it because your CG is relative. After doing this, a look at the control surfaces on the ground when the computer thinks its stable will tell you where your drag is. Oh, don't forget your throttle range during the autotrim.

I most apologize for being an ass the last few weeks. I finally managed to get my F411 FC working on my AR wing and I most say I’m very impressed! All be it I need to do some tuning all features where working properly including RTH which is a big one for me. All in all coming from Arduplane to inav was a huge learning curve and I’m still quite new to inav I have to say it’s functions are great and really user friendly once you get over that hump which ever that may be for each build. My only concern now is failsafe which I really haven’t tested thoroughly yet but I’m using The X8R receiver with QX7 transmitter that’s set to no pulse but when I tested on bench by turning off radio the AR motor spins up and continues to spin until I power my radio back on and it reconnects , then and only then can I regain control. Maybe I need to research slot more on this failsafe thing because I’m not to sure that I have it setup correctly in my AR. I want FS to put the inav into return to home and hopefully that’s what I can do. Can you give me some advice on this? I can confirm though that switch RTH does work and works flawlessly but FS /radio signal loss is a huge concern of mine. Thanks again for your patience and thank you for all the hard work and hopefully you accept my apologies.

Hi Pawel, I should mention that it is not clear what you mean with the word "trim" in this video. I thought I should trim the wing with my RC so that the FC knows what are the midpoints for level flight and for RC input measurement. But on telegramm someone told me I was wrong. Maybe you should add some text to the video so that everyone knows with the word trim you mean to hold the sticks that the plane flies straight.
@shawnzfpv5 жыл бұрын
Autotrim adjusts the servo midpoints for level flight. You are talking about your radio for center on the stick is 1500 on all axis. So.. you should do both :)

@JaviRP974 жыл бұрын
As far as I understand, any stabilized mode (such Horizon) would need the correct trim to fly leveled. So if the plane is not trimmed, once you enable horizon, it won't flight straight regarding the plane, but regarding to board alignment (generally not perfectly aligned to leveled flight). To sum up: you need to trim first and then use horizon, not the opposite.
@rkorenek4 жыл бұрын
Yes you can fly in Horizon Flight mode and do an Autotrim. Then you will be trimmed for all flight modes.

Hello, I just bought my first wing after flying & building quads for 3 years but I'm hitting a snag with iNav. No motor can be seen in the tab or servos in the tab. It is yelling me to goto mixer, but the mixer is telling me to get latest firmware to use. I'm on configuration V 2.0 rc3 Running inav 1.9.1 on a matek F411 wing Omnibus f4 pro & SPRF3. All with same problem. If I use the S800 preset and arm it. the servos move as expected if I tilt the model. & the motor will twitch if I throttle up. But they have no input to the boards. Any help would be appreciated, thanks.

Why have to land to store trims to eprom? It would be much better to have ability to trim in air. I presume for drones it's not an issue but some airplanes, like multiplex, need often small trim adjustments especially when i change to different battery. Its very hard to keep center of gravity unchanged. And every time start and land... Difficult option. Why not to store settings after another 5secs with message trim success.

okay, let's see if I get it right, I leave my model as mechanically trimmed as possible, I start flying in stabilized mode, I activate the autotrim and fly for at least 2 seconds without giving any command so it stays stable, I keep the autotrim mode until the landing and when it is on land deactivates the aircraft and it will automatically save the new servo points? That's it?
@tedhancock686 жыл бұрын
My understanding is that you stay level. So if you have to give minor control adjustments to do so, it's OK. Those commands will be averaged into the final servo position. Perhaps Pawel can clarify?

I learned today that there can be no wind, it has to be on a very calm day, I took a model airplane of mine that flies in manual mode perfectly and I made the autotrim with a strong and turbulent wind, the airplane did not fly but in manual mode, I had to do the auto trim again in the early evening when it was already windless and everything was ok.

Tried auto trim 3 times now on my first INAV plane build and each time it sets up the controls in a cross controlled manner, which means the ailerons are banking right and the rudder yawing left. Thus the plane flies sideways. Not sure why it is doing this.
