• 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.

Gear Stuck

New to this stuff so please bare with my ignorance...

I'm working on a test FSX aircraft as a learning experience. Having no clue how to start an aircraft project from scratch, I copied the FSX Cessna's folder, renamed it & have been modifying things here & there.

I replaced the Cessna's MDL file with one I created in 3DS MAX. Everything was going fine until I came to animating the gear. As the Cessna has fixed gear, my new animated gear will not retract. I know I have the MDL set up more or less correct. My MDL's gear retracts fine when I use it with a default FSX aircraft that has retractable gear. But pressing "G" does nothing when I run it with the Cessna's files.

I've looked through the CFG files, looked at the AIR file, where is this sort of thing set?
 
You have to set extension-retraction times to make the gears work. If the times are 0 as it happens with fixed gear aircraft, the gears don't move.

Here is the cfg file from the default C172, contact points section:

[contact_points]
point.0 = 1, 0.90, 0.00, -4.09, 1500, 0, 0.5, 22.0, 0.25,2.5, 0.7, 0.0, 0.0, 0 (nose gear)
point.1 = 1, -4.70, -4.50, -4.01, 3500, 1, 0.5, 0.0, 0.3, 2.5, 0.7, 0.0, 0.0, 2 (left main gear)
point.2 = 1, -4.70, 4.50, -4.01, 3500, 2, 0.5, 0.0, 0.3, 2.5, 0.7, 0.0, 0.0, 3 (right main gear)

in red are the extension/retraction times, you have to set a number like 5.0 (sec) to make the gears of your model work.

Thanks Elias! OK now this makes sense. My gear is no longer stuck, woohoo!

Thank you for taking the time to explain that so clearly. Much appreciated.
