• 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.

MSFS20 FD using real data is way off

Hi all,

I'm currently in the process of converting the Zivko Edge 540 V2 that I originally made for X-Plane to Microsoft Flight Simulator (MSFS). I have the 3D model in MSFS and will be moving on to animation shortly. However, I wanted to start with the flight dynamics first.

Having spent over 4 years as a member of a Red Bull Air Race team developing the X-Plane model for training, we had it as close as we thought it could be for training in VR. The data from the plane and the sim confirmed its accuracy. I started adding our data to a new SDK project in MSFS, but it just never felt right compared to the XP version, of which I have flown countless hours.

Debug forces in the sim seemed to be in the right place, but the aircraft would stall at the wrong times, drop wings, lose power, and be unstable and erratic. The list of issues goes on. I tried creating from scratch and modifying the default Extra, but to no avail. I purchased several add-ons, including the LiveToAir Edge 540, but noticed many used target_performance.cfg files or had flight models that seemed very different from the visual model, based on the force indicators displayed and their relative positions.

So, I have a few questions:

  1. Can you achieve an accurate flight model from detailed real-world data?
  2. Do you have to use unrealistic figures and tricks to replicate an aircraft's performance and handling in MSFS?
  3. What is everyone else's method for achieving an accurate flight model?
Thank you in advance for any replies and help educating me in MSFS development.
