Re-Maiden of the Dart 250 with iNav 5, and Autotune.

Ya I've noticed inav gets pissed when I trim in the radio 😆

Can you do auto tune in Manual mode or does it have to be Acro?

Thanks!

When i auto tune i noticed the inherant roll as well. I thought it was my thumb swinging the arc from top to bottom. The pitch on was anemic compared to the roll as well. Might just be a wing thing.

How would you give it up trim for the maiden toss?

Your Audio sounds good now. Loud enough for me, I’d say it’s good.

I prefer step buy step videos and your video walk through of INav 5 convinced me to upgrade to 5.0 thank you

Very strange behavior that roll with pitch. My problem has been pitch washboard like bouncing on climbing. I too have had poor altitude smoothing or holding on loiter on 4.1. Both yours and mine seemed to multiply with each undulation. Worse than an uncalibrated hot end temp swing or a toilet bowling multirotor. Mine has usually improved with additional auto tunes.

So when flying between Inav 5.0 and Ardupilot, which do you enjoy flying more? Not setting up, just flying.

Please more ardu flights. 🤗🤗🤗🤗🤭🙏

The drift is what bothered me the most.. the reason i learned arduplane

I lost one of my mini talons to that unstable loiter, the same plane was lovely and stable in loiter under INav 3 but since 4.1 I am learning not to trust it in loiter.

Overall a good re-maiden Keith. The roll with pitch input during autotune seemed odd. Was not expecting to see this. It did seem to become less after autotune, but not completely gone.

Only thing that concerned me was loiter on RTH (safe-home) and porpoise in altitude and speed (or horizon drift). Wonder if this related to the Dart250g descending in altitude as it entered loiter mode? Wound be interesting to descend first (last waypoint), then enter loiter to see if behaviour differs.

On the waypoint mission there was no issues with any of the turns, all very smooth, consistent altitude and airspeed (no horizon drift). I was admiring how consistent and dialled in the horizon seemed to be during the waypoint mission. Even from the initial re-maiden launch horizon drift was minimal. I'd be almost tempted to have a plane do a two waypoint hold pattern vs. circular loiter on a single waypoint.

Interesting maiden and autotune. I have pretty much the same setup as you, except running it on 2S and currently inav 3.0 (maybe 3.0.1). Was thinking of using it as a 5.0 test bed too. I have noticed that I have always felt like I have had less pitch authority than I would like with this wing, but roll is great. I will definitely be looking to see if you can work that one out - my linkages are in the 'stock' setup!

My Diatone Ripper R690 exhibited the same roll-during-pitch movements during Autotune on 4.1. I have way too much mechanical surface movement so I assumed that was a function of a poor mechanical setup. 4.1 also autotuned pitch feed forward to almost 200. I lowered it to 90 (to reduce massive pitch bouncing) and I now have very little pitch authority. I'd love to see you do a P, I, and D tune on the Dart and see your results as well as possibly tweaking the recommended settings to mitigate horizon drift. Thanks for sharing, Keith!

Did you setup your fc so it changes power by distance? If so, can you please make a video? Thank you

Thanks for the vid I have a dart250 With inav 5. No maiden yet…

im having a problem with 5, im loosing my set ups and not sure why, iv had to reload my diff 2 times already.

Interesting, before I lost my talon I also noticed that the pitch was rather sluggish as well. But roll was fine.

Was there any wind?! It looks so stable for a 250g.

Audio sounded great!

hi
how to be able to have dynamic vtx power?

Thank you

Thanks for the video. Good info. I am just about ready to maiden my Dart XL enhanced (inav 5.1, Matek F411Wte, first time using Inav on a FW). I have a question about saving after landing. I noticed you went into the OSD screen to save which was a surprise to me bc i was not aware that was possible. I never noticed the option (i am using 2.5.1 on my quad). I was reading the Inav wiki which says to land and save using the stick commands which shows throttle stick to lower left corner and aileron to lower right corner. Do those stick commands not work or its just your preference to go into the OSD? Appreciate your help

Hi, when I switch to autotune in acro it doesn't show in OSD autotune. So I'm afraid it's some problem with entering this mode. What's can be wrong? Mods are ok and testing in on the desk seems to be OK.

Thanks for the vid. Did you ever find out why you saw roll when you input pure pitch. Have done a maiden on mine amd see the same so looking around for some tips.
