The base on Wind Works free standing tower is 6 foot on a side .
3/4 inch water pipe would make for a lot stronger tower but even then and with a full yard of concert for a foundation.
I wouldn't want to fly any thing over 5 or 6 foot dia. blade set if that.
With my version as a free stander
At this time I don't know just what kind of load it will carry. And that's why I am plan to some
destructive testing . That and every so often I like to tear the hell out of things : )
