    I appreciate all your comments again. Wanted to share with you a video of a milestone for this project.



    My plan from here on is to scale everything up specially rods, bushes and links.

    Awesome work and progress :thumbs

    Given the very limited inherent leverage of the design have you actually load tested the hardware and controls?

    Im sorry I couldn't get back to this any sooner than this. I made some adjustments to make everything more sturdy. Still way to go as I'm relying on too many 3D printed critical pieces such as the motor brackets. They aren't supposed to be moving like that :)

    So this is the first time I load tested it.

    That being said I really like the feeling and I know that it was worth getting to this point and what's ahead too.

    Great to see your rig in action :thumbs

    Just an observation, the motors themselves appear to be moving, suggesting the mounting arrangements need reinforcing.

    Thanks! Your build helped me a lot.

    and yes that's my very next thing to do. Current mounting are 3d printed. Will be sending to be built some metallic ones.
