    Hi guys
    It's been a while,so my 2 dof rig has served me very well,no issues other than the backlash in the worm drives and the very steppy feel in flight Sims, racing is no problem but slow flight sim turns are steppy as hell,it's like I can feel the resolution or something like that ...

    Anyway this brings me to my question I have built up some sfu gearboxes very much like the dof reality items,my question is this would a servo motor and driver be enough to drive such a gearbox in a shoulder mounted balance rig?
    Or look at something else completely.

    Many thanks in advance all you knowledgeable people

    I expect a suitable servo motor and something like the @Thanos controller should be fine.

    Indeed that's what I thought
    Any recommendations as a starting point,and do you think there will enough grunt.

    I was thinking of the 80 or 90 type with the matching drivers like they use on the sfx100 or sfx80.
    Might just be a large outlay if it wasn't grunty enough.
    Although I could then maybe just get some sfx linear actuators and make use of them.

    Yip sounds like a plan.
    What are your thoughts regarding enough grunt to turn a sfu style gearbox like the dof reality one uses,I assume it should be ok.

    Any views either way would be usefull

    Hi Thanos
    In that link you sent me,there is a motor A and motor B type.
    Which is the motor I should order do you think
    Many thanks in advance

    I think it shows in the pictures the difference. Most prefer the type A.
