    Hi. Finally after two years, I can post that I have almost completed my 6DOF rotary platform.

    it is based on @Motion4Sim as a simulator for xplane 11 principally.

    I still have to finish the pushrods and finish welding parts together and place the cockpit on top. I’m using retic pipe for now .

    Having completed this proof of concept setup on the weekend and testing with no limits 2, I’m very excited with the potential of the sim and can’t wait to fit the cockpit.

    I hope to put some details together soon and eventually a build blog.

    looking good, nice compact build - what type of motors / gear ratio did you use ? what is the length of the arms ?

    80st motors (750W with 3000rpm) and 15A drivers . 1:50 gear ratio. Arms will probably end up 560mm I think. The crank levers are 180mm

    I hope you can fit the cockpit on it given the weight limitations of these small servos...

    Here what it takes to host a whole nose cockpit:


    And how it looks on actual flight:

    Haha! Thx thanos. I won’t be mounting the cockpit you see in the background. That might be project no. 2.

    I’ll only be using a small single person cockpit.

    I also wanted to thank you for your tutorial on building the powerbox, which I did. It has given me a good idea of power usage to date, and will be interesting to see power usage when I put the cockpit on top. Total weight for the 6 motors to carry will be circa 130kg, including me.

    I did reach out to jmsgrande for info on his build. Would love him to do a build blog for his 737 sim.

    It was years of planning, since 2014... See a scale model he built at the time...
