    Thanks Skuldi,

    This really helps me understand how flypt workshug:
    I need to adjust the scale of my rig in flypt, because now I only get 5 degrees of pitch or roll on my rig when I output 10 degrees in flypt .
    Maybe it is also possible to get it done by changing the gain ?

    jupp, but at the end i left it at 1.000 and only changed the scale of my rig. i can't remember what the problem with gain was.

    EDIT: leave gain at 1.000 try changing skale below that

    I did some test , changing the rig dimensions to other then the real size seems to work but I find it a strange solution.
    What helped the most was changing the range in the rig module , I changed it from 180° to 95°
    now my roll output in Flypt is 10° my rig is at 10.2°
    pitch 10° give 8.7° on my rig.
    changed values of L2 and L5 for 40mm so that pitch ended up at 9.5°


    L1 to L6 compared to sim calculation picture , made the changes more visual for me
    flypt compare simcal.jpg


    One thing the pitch and roll output do they just add up in the output?
    if i set pitch to 6° and then 6° of roll. one output to a motor will go to 12° ?
    that is maximum range of my rig
    so does that mean i'm limited to 6° for pitch and roll ?

    After tuning flypt with MSFS2020 , I did my first test flight in VR :cheers
    It worked , I did reduce the input gain a lot, just to be on the safe side
    In VR it feels great in non-VR it is too passive.
    I got 7° of Pitch and 6° Roll max on the rig but it seems te be enough for VR.

    here are my settings for FS in VR mode.

    Movement is still a bit shaky when output is slowly going up or down.

    I tried to get Elite Dangerous to work.
    But source module does connect but it doesn't recieve any data from the game.
    Anyone got some tips?

    For now I'm super happy , I got it working.
    Lots of work to do but we're flying.:thumbs

    You can try to reduce PWMmin in SMC for smoother movements.

    may you could describe how to mount the 100mm brackets for the motors? And please the needed parts?
    thank you
