• 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.

P3D v4 ISimObject's and the new P3D V4.5 Indago UAV Quad Drone

Hey all,

In the newest version of Prepar3D V4.5, they have a UAV called the Indago, a quad drone. Small little RC drone.

They use a unique set of XML's to control it with. What I would like to know is if it has a DLL somewhere that helps to control it, because supposedly it does, but I cannot find it. And also where the lists (Libraries?) are for command strings, events, control input options, etc, for when someone is creating something like this, or wishes to experiment and make changes to this existing unit. I cannot seem to find that.

Presently the drone uses an XBox control unit for yoke. I have cloned the drone and it shows up in the sim, and I am trying to make changes and things to experiment with how it flies, etc. I would then like to create some of my own things in the sim using this tech. But if it needs special DLL's and things, then I might be out of the picture as C++ is a bit over my head, at least presently.

Also... What is 'PDI'? I have heard this term mentioned in auto pilot systems.

Thanks for any input and enlightenment you might have on these subjects.

I am hoping the Indago is a XML only way of doing what is normally a DLL, but could instead be done with XML files. That is what pulled me into the interest of this vehicle.


This is the folder structure in the Indago_UAV folder which is located in the Misc SimObjects file directory.
Note the various files for Mass, Aerodynamics, RotorSystem, etc, etc. In the 'Controls' folder is a Controls XML. This has the various keyboard mapping layouts.


This is the UAV in P3D V4.


The real deal. The LM Indago really exists. In the sim, it has auto-hover and can be controlled by XBox. I would like to change the controls to a standard joystick, but cannot find the name strings to modify the Controls XML.
The Indago UAS in P3D v4.5 was impelented using PDK and the module is located inside SimObjects\Modules\Quadrocopter.dll library. You can see that sim.cfg file contains CategoryId = GUID. It loads data from xml files as parameters. Properties that exposed in Control directory can be mapped from UI to keyboard and Joystick and can be accessed from SimConnect clients.
