    Hi All,
    I to have started the journey, First time builder, long time sim flyer.
    I got very lucky and bought actuators from a member with all electronic to go with them.
    So all to do now is build aluminium frames and assemble......Hopefully.

    Also have trouble working out the correct size for the base and top platform.
    I've done some autoCad drawings but it seems so big, does anyone have comment on the size difference between top and bottom platforms??

    They are,
    But verify the dimensions, I made it to be the most compact possible.
    You might want it larger. (easier to enter/exit)

    ideally, yes..
    but after all you make it how it suits yiur build.

    ive learned that the design follows the circle.. and triangles 30 , 60, 120 degreees

    Another note,
    The actuators size are one of the most important factors here,
    And an ideal hexapod, to have the largest dof in all 6 dof, would be a simetrical one:
    Same size top and bottom
    Same point where actuators touch each other (same joint would be great, but I don't see how)
    And equally spaced 360°/3=120°

    Hi pmvcda
    Thanks for the information
    I'm completing a Cad draw of the actuators that i have, mine appear to longer than yours, so not too sure on what the % increase in platform size would be to cater for that

    you have to becareful what you increase, or else the actuators pivot beyond structural limits....
