• 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.

NULL flight dynamics for SDK driven model?

Can you create a NULL flight dynamics for an SDK driven model?

I'm after something that will maintain the attitude and velocity set with the SDK, maybe by configuring it to have an enormous wing and tail area but with tiny control surfaces and no drag. Would this work?

I want to use FSX as a visualisation tool, setting the position, attitude, and velocity of the aircraft, and the positions of all the control surfaces, from an external SDK program. This program gets updates, say, once a second from a real model aircraft. I can't disable the FS flight dynamics, so in between updates the FS aircraft tends to take a nosedive before being corrected by the next update. A rather unpleasant thing to watch! I'm actually using the Cessna 172 configuration files but with my own .mdl file.

Any suggestions gratefully received.
 
I've recently done exactly that. I put the sim into Slew mode so that the no aerodynamic modelling is performed. You can change a setting in the fsx.cfg so that the flashing "SLEW" message does not appear.

I'm not sure whether I've tried slew mode but I suspect it will give similar results to pause, which I have tried. This didn't give me quite the effect I'm after. For one thing, the control surfaces don't respond. For another, it would be nice if I could use the dynamics engine to move the model along between updates, as long as it moves in a straight line in the direction I told it to move.

Thanks anyway, and I will certainly try slew mode tonight.
