Thanks for the link. That's an extremely interesting read with lots of breadcrummbs in there.

• Laminar's internal QA capabilities were expanded with a release manager and test teamk members.
• Next-gen terrain supposedly has streaming capabilities.
• Minor releases are those that do not affect third party developers, but may otherwise include substantial changes and additions.
• 12.1.3's ATC update is going to bew "substantial".
• Better multicore support in active development. First release maybe in 12.3 or 12.4.
• Skeletal animation support in active development.
• The foundation for exposure system fixes has been laid; basically now under evaluation by the art team. MMay be part of a seperate release once ready for reasons of urgency.
• Safe mode is in development to easily launch XP without third party content.
• Developer documentation is being revamped.
• Eye tracking for VR is work-in-progress. This will offer better performance by only drawing areas with vision focus in high res.
• Substantial networking improvements in testing by XP Pro users; general audience release once they say it's working solidly. Next step will be multiplayer via lobby.
• Minor 737/A330 updates upcoming.
• Improvements to Minecraft clouds in development/testing.
• Lighting changes in 12.3.0

🤣 Ya the incarnation of of lwt1971 from the MSFS 2020 / 2024 forum 🙂

Thanks fro the resumé 🙂

They do not yet mention a fix for the rolling bug on prop aircraft, which pretty much kills my whole experience of flying prop aircraft in XP12 right now 😕

Would like to hear from Austin on this bug...

I really hope this chart, from 9 months ago, will have an updated version soon, seems like they are well within the lower branches (concluding that from the fact they are already talking about better multi-threading and descriptor sets)

What kind of bug? I haven’t notice or read about such a bug til now.

I had found it in pretty much all prop aircraft, but was specially evident in 3 models of DC3 I used - AWX, VSL and LES.

Assuming you have a single or multi-prop with the props all rotating, say, clockwise (observing from behind / towards the nose of the aircraft), you'll notice right rolling tendency, quite evident in some props.

At first I thought something had changed in the way XP12 now calculates the prop effects, and the fixed aileron and rudder trim settings (usually set for cruise) were overdone, so I decided to simply NIL these in PlaneMaker for all of the three models as well as in the default C90, but still your prop aircraft will roll right at pretty much all configurations / power and speed regimes, when they should at most exhibit a left rolling tendency (CW rotating prop(s)).

The opposite will apply if the props are CCW - a left rolling moment then...

I even noticed this might already be known to some elements of the LR team because if you open the default Baron 58 you will find that they moved the starboard engine axis outside (towards the wing tip) more than the critical (left) engine, which is totally unrealistic IRL given that for a CW rotating pair of props that would create an even more critical situation in case of port/critical engine failure 😕  but indeed it helps somehow mitigating that right rolling tendency that shouldn't be there.

I reported it through the bug portal and it was acknowledged, and I was told they're working to try to find the reason for that, and a fix. I believe someone mentioned it'll come with 12.2, but it's not mentioned in the list of the upcoming bug fixes ?

@jcomm thanks for the explanations. Interesting. And if they have aknowledged it, there must be something to it. I haven’t used any of the decsribed aircrafts and haven’t noticed it in the SR22 for example but will look more into it.

It's present in the SR22 too 🙂

In the twins you tend to see a rather asymmetric distribution of lift near the outward nacelle of the port engine, compared to the equivalent vector on the starboard one.

I mentioned it, but someone told me this has no effect on the rolling moment ... Well, maybe it has a different origin. I just want them to fix it - it irritates me a lot, and makes me play DCS and IL-2 instead 😜

Did you notice that by displaying the force-vectors?

I will test this evening the flight feeling of the C172 because at least I know how it feels in real.

I am still laughing at the thought of Janov having advised you to do so, love his sense of humour 😂

He was actually joking about me changing my mind regarding flightsims 🙂 

@Franz007, If you go testing the default C172, do so with CAVOK weather preset, no winds / turbulence, to exclude any other factors.

Please report what were your findings.

Thx

EDIT: It had been a while since I had tested the C172, and indeed it's probably the only default CW rotating prop that doesn't exhibit that right rolling tendency, even though it has default fixed trim tabs set at 8/1000 for aileron and 5/1000 for rudder.

The SR-22 you can easily check that will roll to the right, and it has the fixed aileron trim tab at 1% but even if you make it null it'll slowly start rolling right.
