Great vid, not a waste of time or boring at all.
Thanks!
I assume in the post above you meant “ ‘upwind’ mode, the big spiny thing acts as a turbine”?

In the downwind mode the propeller is *always* a propel...

Re: Downwind Faster Than The Wind - update

I am willing to bet that people getting so thoroughly owned are still living happily in their oblivious world of fake news thinking they won that exchange too.
