    A little more pitch/roll and heave would be good for immersion, otherwise looks good!!

    Just finished the mechanical portion of my 3DoF / 3 x PTActuator + P1X build.

    Having 3 actuators, I took the advice of noorbeast and focused on weight distribution and CoG. As a result I bought some additional cut 16040 profile and 8080 brackets from SimLab (who have been amazing TBH).

    Though it does increase the footprint - the 'side pods' have allowed an equilateral actuator triangle to be created (110cm) . The weight at each actuator is within 2Kg when seated (I'm 80kg). Frankly I'm amazed at how stable it is.

    Looking forward to the tuning now.

    An actuator is located on each corner, as the wheels of a car are.

    The downside of that, during very fast actuator movement, is that it is possible for one actuator to lose contact with the ground, which effectively is a loss of control from a motion simulation management perspective.

    Ok that is understandable. I was thinking the 1 up front 2 in the rear setup but is there another advantage or level of immersion with 4 corners ve the triangle concept? Long term I would like to add yaw as I understand it .

    A triangular base needs to be big enough to provide stability.

    Do you mean yaw or traction loss, as they are 2 different forces?

    Or I guess is it considered better use 4 if you also
    Oh boy, well both honestly but my goal is to better feel that moment of losing the rear or a front lock up would be nice to feel that or pushing through a corner.

    Maybe you need additional layers for traction loss...
