how did you manage to bend the sheets of metal like that

Each of the the ribs is actually made from a cnced mold using bondo glass. There is also a carbon fiber strip used to support the joints and a chain to prevent sagging. It is very strong, in fact one of the ribs hung a little low and wore away an eighth inch of the aluminum base. If interested I'd be happy to post some pictures. I'm going to try to find time to take some readings before the summer is finished.

At this point I don't have any of the electronics hooked up. The video was in about 45-50 mph gusts, but in low wind conditions it doesn't really turn well. It's been up for about a week with low wind and high wind, so I haven't been able to find the lowest speed to make it turn.
I first plan on keeping it up for a few weeks to make sure no structural problems before I invest the time to connect it up. I'll post back then.
