It was very cool to see it up close. I forgot to ask him what type of glue he used to attach the mylar skin to the carbon ribs. Do you know? The reason I ask, lots of Ultralight type aircraft build up a similar wing using aluminum ribs instead of carbon, and dacron skin instead of mylar, but they have trouble keeping the dacron glued down to the aluminum.

Of course they also worry about paint jobs and asthetics more than we do and they fly at over 60mph so there is a lot more stress on the wing.
