• 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.

Shake and tremble

Hi all,
I hope someone can help...
I am building a flight model and I am seeing a problem when I start to use a real world 'dry weight' in the aircraft cfg file. The model shakes and 'trembles' when it is not running and just sitting on the tarmac. This problem goes away when I reduce the dry weight but everything else is built around that weight so I would rather use it correctly.
Any ideas as to where else the fix for this might be?

check your suspension values, I believe this is a condition of the landing gear being too stiff.

What rk is saying is the problem might lie with the aircraft.cfg contact points values. There is no magic solution and for any sensible advice one would have to have more data, including all contact point details and the rest of the aircraft.cfg data.

It can also be that you need to increase your MOI values in the weight and balance.

Hi all,

It turned out to be a bit of both. I actually went to the trouble of properly calculating all the MOI and when that was right it seemed fixed. But then I got ambitious and fiddled with contact points also. All is looking good now so thank you all for your advice.
