Has anyone attempted recording using a Hoverboard or similar device to get smooth video?

I haven't, but I'm sure it would help (depending on the terrain).  I have thought about using a skateboard for some smooth panning shots though.

As long as you have the hand eye coordination to do it, it would be possible.

The result will be great.  But I don't suggest you do it because it's dangerous operating Segway with one hand.

Look up this thread, "HYPERLAPSE - Osmo on an electric skateboard"(was done around 9 months ago), there are also a lot more on utube,also with the Segway

This guy (2:00 mark):

I've operated with the OSMO on the "hover board", you really do get  smoother footage, less of the up and down movement, but if you don't hold your hand still, it still shows a little bit (I don't have the z axis).
