    No answers. Only Ali Express. I did find another company that sold kits but I think they are most likely in China.

    Note that there are much less expensive alternatives for AC servos now. Check out this thread:
    https://www.xsimulator.net/community/threads/aasd15-alternative-thanos.18984/

    Most of the linear actuators are associated with 6dof but they could all work for a SFX system as well. I decided to make my own design but it’s just in my head for now.

    I have seen SFX-150 stuff also. You might try a search for that.

    I bought my extrusions on Alibaba. Had to modify the printed sliders a bit, but they fit fine now. The motor/actuator sets I am purchasing are RATTMOTOR on Amazon (750W, no brake). $149/set.

    Yeah, I ended up buying my aluminum from the item 24 website and I had to shave my sliders a little bit too. but I found for my motors a 110v version on Alibaba, which I decided to buy instead of the ones suggested on Amazon.

    No need to purchase a 110V version. Just change the motor controllers' low voltage alarm to 100V and run them on 120V. They run at half speed, but that's ok. No need to run 240V circuits or purchase a transformer, like some have done.

    The ST80 Motors will have a max speed of 2300rpm, instead of 3000rpm.

    Don´t know where the rumor come from with only half the speed.

    I'm not sure I understand what you mean. What is the rumor about half speed?

    2300rpm instead of 3000rpm is not half of speed.
