Any experience with a reclined center position?

    I am starting the planning on my next sim. This will be my second sim, Here is a link to the first one. While tuning and testing, I found that if I tilted the rig back, it shifted the cg enough to always keep the drive slack "pulling" This was a great fix to the slop of the old parts I was using, But it also gave me an idea.

    I really liked the feel of being reclined. My use is exclusively VR, so any reference to standard position or need to line up to a monitor is unnecessary. It also added a "G-force" effect of being forced into the seat.

    I did not change anything too much, just a few degrees, but the effect was noticeable.

    Now that I am planning a new rig, I definitely want to incorporate the idea into the design, something I did very little of last time. It also fits into the main design point of the new sim, as to be Low Profile.

    I am picturing a 2dof+TL frame mover, GT sitting position, with maybe a 15 degree recline as the Zero position. But before designing the whole thing being "That far off" I was hoping to get some feedback. 15 might be way too much, 30 might be better than I imagined. I dont think rocket ship 90 is appropriate.

    So today I taught myself autodesk inventor. It is free for home use and I was able to check all interferences upfront.

    Working with Inventor, this is simulated with approximate forces for motors and rider, so should work out about like this
