hello, we made a balance part at the other end of the spinner, so the spinner itself is in the stable status. the truss in the video is 4meters wide, so it will be a little bit swaying, but it is safe. And if the truss is 3meter wide, it will be much more better.
because the truss is very wide, so it is bowing a little, but it is safe, we have sold many of this model. And if we make the truss shorter, it will be better, what you saw in the video is 4 meter wide.
