I've put together a quick YouTube clip showing the dragonfly wings in motion, they make quite a satisfactory flutter I reckon! 

Note that it has gone back to a single pendulum.

Here's how I reckon the dragonfly model will look when its complete.

Oh, and my apologies for the music. That's what happens when you put GarageBand (actually Logic Express) in the hands of amateurs. Its like the old days of DTP. I was rubbish at that when I started too. Five years from now, my music will be fantastic. Taa daa!
