    hello there
    i just started a 3DOF build and looking to buy the motors for the rig i found these:
    https://dutch.alibaba.com/product-detail/12V-24V-High-Torque-Worm-Drive-62089903756.html

    The 12vdc 200watt 60rpm come with a 50:1 and
    the 12VDC 200watt 200rpm come with a 15:1 gear box.
    witch 1 is better for a 3DOF.
    link to my build(in progress):

    documentation link:

    With a compact design keep in mind the motors used to drive it need to have plenty of torque. You would definitely want to use the 12vdc 200watt 60rpm that come with a 50:1, on my compact rig I use 200w + 60:1, I found 50:1 initially could not be back driven when new (can't move when unpowered), but after a period of use they loosen up and can be back driven, which in my case was a pain as I also used my rig as an office chair.

    When using a rod and lever they are most torque efficient at 90 degrees and effective torque utilisation drops off rapidly over about 38-40 degrees movement in either direction. The yaw motor, lever and rod look to be very inefficient with the current configuration.

    box section aluminium is not very strong the way it is bolted together

    it will get loose over time imo
