    Hi there,

    My project is to build a flight simulator with MS FSX software. Last year I built a fixed base simultor, but now it should be moved by x-sim with velleman and sabertooth and two motorized car jacks. For informition the simulator has a weight of 500kgs around.
    Well, the car jacks are placed at front left and right, the back is on a fixed single axis. I have no problems to let the jacks move the roll axis, but is it also possible to let them move the pitch axis simultaneously? No idea how to do it - highly appreciate any help...

    You should be able to add the extra motion in the math section by adding an extra force to the axis required.
    That is how I have 3 forces of motion on two axis.

    Many Thanks for fast reply!
    Ok, that means it should be possible somehow.
    Anyway, the two axis I have now moving opponent when the plane is in roll movement.
    Now with the pitch roll force the two axis have to move the same direction. How can I manage this?

    can you take a video of your current sim in action? Then we can assist further once seeing what it does.
    Thanks, David.

    This is how it works now:

    and this how it should in future additional:

    Hope this is enough to show what to do...

    OK, I will have to work in car terms for me to understand...
    Pitch - longitudinal force
    Roll - lateral force

    With a car game , starting a race gives pitch to represent the lift of a car under acceleration, and roll when I turn corners.
    These forces both work on my 2 DOF system together , so if I brake going into a corner, the sim dips forward and to one side, then if I accelerate out of that same corner, it lifts whilst still rolling into the corner.
    For flight sim, you should be able to program pitch and roll into each axis. You would need to invert the force on one of the axis to get he best motion. All you do there is tick/untick a box in the math section.
    Do you actually have a sim running yet and or a setup to test these movements?

    David,

    many thanks for your help in my case.
    Yes, it is similar to your car setup....
    Yes, I have a testing setup.
    If I understood you the right way, I have to put roll and pitch forces on each of my two axis together? Means pitch AND roll per one axis?

    Yes, pitch and roll on each axis, and then adjust them to suit the motion, meaning, invert the motion on one of the axis to get the correct roll motion. Otherwise it may just go up and down on both axis.

    ok, I tried it with the test panel. I choose in the math section the g-force a second time with slider 22 (21 is active also). But now the jack just runs only when I move the slider 22. What did I wrong?

    I think the test panel - tablet is there to make sure that x-sim reads the motor control boards. So as far as I know, you cannot set two forces that way. You would need to actually have a game going, and then put forces in, Start with one on each axis and add and re-test.

    Many, many thanks so far. I ticked in the math section - ad force - and it works now. :D
