• 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.

V Stab Incidence

I'm attempting to model in FSX the effect of a V stab installed at a fixed (non-zero) angle of incidence to the fuselage, as found on the Hawker Hurricane or Curtiss P-40 for example. I can't spot any entries in the .cfg or .air file directly relating to this. The effect I'm looking for is a progressive variation in directional trim with changes in airspeed. If anyone out there has accomplished this or has any thoughts as to a solution, I'd much appreciate hearing from you. Thanks.

In FS the only effect the Vstab or fin has is on lateral stability according to its area and distance horizontally and vertically from the wing center of lift. Since there is no Vstab incidence entry in the config file, its incidence is ignored.

Thanks Roy, I was afraid of that. I guess I'll have to come up with a workaround of some sort to simulate the effect I was looking for. I'll close the loop here at the forum if I come up with something suitable.

Not a lot of progress to report, unfortunately.

Here's a related question, perhaps one I should have asked first: is there a way to adjust the strength of the slipstream effect in FSX, without tampering with engine or propeller parameters? It seems to me that the slipstream effect dies off very quickly as airspeed rises; as such, perhaps there's not much point in trying to simulate the effect of an offset fin, which would balance off yaw due to slipsteam, in the cruise condition. By the time you achieve cruise, yaw due to slipstream is basically undetectable (the FSX turn and bank indicator doesn't really help matters - the ball seems very underdamped).

Any thoughts on this? Is the slipstream effect "hard-wired" or can it be modulated without disturbing engine and prop characteristics, or tampering with yaw stability or MOI?
