Weren't these "stutters" related to Simconnect somehow? I remember reading something about it back when I was using their Comanche in MSFS 2020 and suffering this weird "jumps". I was never able to fix it and ended up uninstalling the Comanche. And that's the reason I haven't bought their Aerostar.

This is the only add-on that behaves like this (and I own almost all of the GA / tubeliners around).

 

So do I! I Own most of the GA:s out there, both for MSFS 2020 and 2024. And this is the only plane that behaves like this. There are some "jumps" in FSlabs Airbus, but not as much as in the Aerostar... I remember HPG:s 145 sufferd the same issue some years ago, it ended up in that I parked the heli for good, since there where no complete fix from the developer, the "jump" got less prominent, yes, during some updates from the developer, but it was never perfect. 

Same here: had this nonstop annoying issue with the Comanche in MSFS 2020, then again with the Aerostar in FS24 -- on a completely different computer, no less.

While the symptoms may be lessened by fiddling with the turbulence and camera shake options, the cause is almost certainly related to SimConnect's interaction with A2A's external flight model. I could've sworn that I read an A2A dev on their forum awhile back specifically talking about it, but now I can't find the reference.

Well, I just bought the Aerostar today and this jerky motion was driving me crazy and I traced it down to Navigraph Charts for EFB and Navigraph Charts In-Game Panel. As soon as I removed those, the stuttering went away. Just completed a test flight. So perhaps this will be helpful to someone in this thread. Cheers.

I don’t use Navigraph (tho I keep intending to…). I can report that the Aerostar and Comanche both are and always have been smooth as silk for me.

I can vouch for the "hiccups" in the Comanche and even I noticed them in the Legacy. The adequate description of "hitting a bump in the road" would be applicable. I don't use Navigraph and not sure what triggers this phenomenon. Hoping to learn what the source is soon. Very distracting. Like mentioned earlier, it's only the A2A AC.

I think it comes from A2A's "turbulence" setting in the EFB. For me, if you pull that turbulence slider down to the far left (and have turbulence in MSFS2024 set lower than 'realistic') the bumps disappear.
