    Hi all,

    After getting excited on this forum, I also want to build a 3DOF simulator myself.
    At this moment I am racing with Arsetto Corsa on a fixed base rig:

    I already purchased 3 motors for my rig from ebay: https://www.ebay.nl/itm/283895430976
    They are geared Trolley motors, ratio 25:1, output 140 RPM at 180 Watt.

    So, 2 motors are for roll and pitch angle, but I am still in doubt about the third motor. Which movement can I best simulate to achieve maximum immersion
    1 - Heave:


    2 - Surge:


    3. Traction loss:


    Would love to hear some advise.

    It really is about personal preferences.

    Traction loss is the most common choice, particularly for race games.

    Personally I went with heave on my compact rig and the way it was done, using a heave assist knee, means there is a small surge as it transitions an arc on the pitch axis, which I take advantage of with a race harness and how I set my surge settings.

    Ah, I see now. Very interesting! This could also be used in the design of the first video. And I see they are not that expensive.
