was asking the designer a few questions this afternoon, so that I'd have the answers ready for any enquiries from potential buyers. I asked him that as it doesn't "furl" (turn itself out of the wind if it's very strong), should we recommend people drop the tower prior to predicted heavy winds?
"Well, there's absolutely no need, they're built to take it - they regularly run in constant 60mph windspeeds, sometimes for 36 hours at a stretch at our test site in Montana!" - now that's an answer!
