    Hello!

    I'm now at a point where i can begin to think about the next step in the Build, i got Pitch and Roll done and works good, next is the Yaw Axis.

    I'm considering 3 options, keeping in mind that - It is for VR Setup, mostly for Flight Sim:
    1. Classic like most 2DOF with Traction loss, placed in front of the existing U-Joint
    2. Right underneath the Ujoint close to the floor
    3. Above the Ujoint,
    My thoughts on the matter:
    First would be easy to implement, is proven but more akin to driving sims. Second is also easy to do but needs slightly more work and adjustment but comes closer to immersion. Last one would be the closest to immersion, it is possible in the footprint, sturdiness of the rig, but adds additional weight to move, it can be balanced out somewhat, but it will increase the demand on the two existing motors by additional loads. Worst case, would be a redistribution of the balance, and adding a gas spring system to reduce the load factor on the motors.

    I’m also not sure if the additional work is worth it, it is as is, quite immersive. Maybe the next leap would not be a yaw axis per se, put a real 6dof rig, which is out of range anyway. So i’m not very sure if the additional footprint, work and materials are worth it.

    I would love to hear your thoughts on the matter, also i attached the photos of the current status and the work that lead up to this point ;)

    Cheers

    If it is for flight only then yaw is the way to go, traction loss is not yaw, which is why it suits race rigs, as it is akin to the rear end breaking loose.

    I am not sure construction wise what you have in mind for options 2 and 3, so you may want to expand on those a little.
