• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

    MSFS Aircraft speed - deploying flaps /

    I think we need to recognize MSFS is a 'game' and part of that game is people wanting to tweak the parameters and seeing how the aircraft reacts - a response "you know nothing about aerodynamics so don't do it" is unlikely to motivate people to experiment with the sim. TBH I've blocked WarpD...

    MSFS Modern flight model has no adverse yaw

    Thanks Roy - that's some great flying experience - so your advice for modelling adverse yaw in MSFS is "it's not an issue, concentrate on other stuff?". (actually I'm assuming you're an MSFS modeller - apologies if not). Unfortunately for my planes adverse yaw is definitely an issue (of course I...

    MSFS Modern flight model has no adverse yaw

    Which types have you flown with 'positive yaw' (I'm assuming you're a pilot)? However, I'm not sure the answer helps a question of how to implement adverse yaw in an MSFS aircraft unless you're suggesting it's the wrong question.

    MSFS Modern flight model has no adverse yaw

    Watching the May 26th Dev Update (ref Sim Update 4) more carefully, it's clear the adverse yaw parameters are coming in the NEXT update, i.e. there will be the ability to configure differential 'aileron up drag' and 'aileron down drag' which is not possible in MSFS today i.e. the SDK settings...

    MSFS Modern flight model has no adverse yaw

    LOL after all this discussion I actually took the Asobo 172 up for a spin and the adverse yaw is imperceptible ( see ). Note in that test I stabilized the plane, and then hands-off I moved the ailerons using the keyboard so there's no other control input. MSFS Assistance / Piloting Settings are...

    MSFS Closing an MSFS C++ gauge

    well done... nice job. I hit a related issue with HTML/JS gauges that if the user quits via the [X] upper-right-window then not only do the gauges have no clue but Asobo's code that persists data to the Key/Value store (GetStoredData(), SetStoredData()) doesn't know either and the keys/values...

    MSFS Modern flight model has no adverse yaw

    This morning I woke up with what may be a great theory of what's actually going on in MSFS with adverse yaw! I've always had a challenge with glider flaps in FSX and MSFS because they are modelled as plates independent of the main wing which means they ALWAYS ADD DRAG whether they go UP or DOWN...

    MSFS Aircraft speed - deploying flaps /

    I don't think there is a MSFS parameter you can set which prevents the flaps being used above a defined speed (just damage thresholds). You mean you click 'flaps down' and nothing happens? Possibly there's additional code in the plane which is controlling the flaps. Which plane is it - are the...

    MSFS aircrafts / flight model

    that question should really be in the 'flight dynamics' section so other people can find it - those values are explained in the sdk docs:

    MSFS Modern flight model has no adverse yaw

    Thanks bstolle are you basing that on FSX or MSFS? & could you suggest a 'simple' parameter change that would cause significant adverse yaw on an MSFS aircraft? I hope you're right because I've found it difficult to program in adverse yaw for long-wing-span gliders where in RL it is quite...

    MSFS aircrafts / flight model

    ok one thing at a time.. did you find the screen that shows where your CoG is? (I included a screenshot). If you did, maybe post a screenshot here (that would be best) or just confirm where the CoG is - i.e. is it in the right place, or is it too far forwards hence your issue. When we're done...

    MSFS aircrafts / flight model

    Do you mean the plane tips onto its nose when you are parked, or do you mean the nose tips down when you are braking on the runway after landing, or something else? The quick thing to check is you haven't moved the "CoG" (center of mass) too far forwards - see here If the center of mass is...

    MSFS Interesting thing about how MSFS creates mouse zones.

    hey Antony just a brief comment - I appreciate you posting these things as you find them... saves all of us a lot of time. I also think the 'nested' rectangles (that inevitably occur when multiple 3D objects have overlapping rectangles) have a simple Z-order based on the distance from the...

    MSFS aircrafts / flight model

    lol I have not much of a clue - I haven't seen any 3rd party planes with encrypted content yet - I would guess the technique is to override Waco files in the virtual file system with your own, in this case the flight_model.cfg. You might not be able to get the content of the current...

    MSFS [SOLVED] Can I correct the pitch attitude of MODEL?

    thanks Roy but FYI in MSFS both [AIRPLANE_GEOMETRY] wing_incidence and [AIRPLANE_GEOMETRY] htail_incidence have a huge impact on the flight model - that's changed since FSX. The htail change is like a trim adjustment on steroids, and the wing adjustment has the kind of impact you'd expect but...

    MSFS aircrafts / flight model

    I'm sure you'll get there, it's just quite a grind. If it helps, the Asobo Cessna 152 flight_model.cfg has a comment next to each parameter which will provide more clues. Some parameters do NOTHING so that's not particularly helpful. You can quickly make a plane more agile by increasing the...

    MSFS [SOLVED] Can I correct the pitch attitude of MODEL?

    Hi the aircraft I'm working on has the model aligned to the GROUND, i.e. the Z-axis is parallel to the ground when the aircraft is parked (the modeller took the side-profile of the plane when parked to bootstrap the model) The result is after much flight_model.cfg tuning I now have a plane...

    MSFS aircrafts / flight model

    Hawk on your post above you can set a drop-down box right at the top to say which sim you are using, e.g. FSX, MSFS, P3D. You mention Asobo in your post so it's clearly MSFS, but you can speed things up by making that clear up front. The docs for flight_model.cfg are here. Also you might end up...

    MSFS Change Animationspeed

    My advice is get more familiar with model XML code before you worry about sounds. Mouse handling is in the example I gave above. The DG808S and the AS33 are MSFS gliders with a LOT of example code in the model XML and you'll find you've hardly started. The DG808S has some simple gauge needles...

    MSFS Change Animationspeed

    Here's an answer more specific to your canopy, using a local variable to control the canopy animation. Note for a glider canopy there are usually TWO animations, one (or two..) for the lever the pilot uses to open the canopy and another for the canopy movement itself. The LEVER animation...
