    @Pit
    Here is product I saw posted on race dept.


    If I give it more room say over 15 ft back and forth, and move much faster (higher acceleration), per your experience would it be better? And how to setup the washout filter on this type of long surge?

    You are going to build a simulator or you bought the commercial one shown in the video?

    I like the idea of long surge table/track. Wonder if this could offer better sensational feel on speeding and braking. Think maybe build one with 3dof on top. Thanks.

    There are a number of platform axis design, but all have limitations in how long they can sustain a sensation of Gs. A G-Seat and things like harness tensioners are in my view a more practical and certainly compact way to simulate sustained Gs.

    I agree g-seat type “tactile” solution is more practical and compact.
    I wonder if any one has experience on both g-seat and sort of long track/table surge experience.
    I looked the video and Pit’s rig and his idea that seem not really hard to implement a long and fast moving surge track (or sort of cable solution). That can give a true inner ear motion cue (acceleration and braking):
    “There are two sets of end organs in the inner ear, or labyrinth: the semicircular canals, which respond to rotational movements (angular acceleration); and the utricle and saccule within the vestibule, which respond to changes in the position of the head with respect to gravity (linear acceleration).”

    Yes, if you look in my build thread, my first sim had a surge table.

    Just checked your video. It seems to me that the direction of your surge table was wrong.
    While accelerating, the rig shall move forward (positive acceleration). While braking, the rig shall moving backwards (deaccerlation or negative accerlation).
    Do you agree?

    The way simtools worked at the time, this felt the best, as braking was most felt on the transition of moving forward and then back. Hard to explain until you actually experience it.

    Ok, Just did qick calculation for 0 to 60 mph acceleration in 5 sec that is 17.6 ft/s^2.
    To make my inner ear motion cue correctly just for 1 second for such acceleration, I need to move the rig in 8.8 ft (in 1 sec). To feel 2 sec of such acceleration, I need at 36 ft long surge track.lol
    I would imagine that to have a 15 ft long surge track, may not with that fast speed, but combine a g-seat and seat mover could yield a remarkable realism sensation. Need a solid build to sustain such force. Ofc, no monitors, vr only.
