Arduino Air Ray and a Arduino DragonFly

Hello guys! (Nick if i posted this wrong please put it in the right map, i just dont know where to put it)

I wonder if people are doing something like this project i saw on Festo Youtube.

I think its easy to make with some balsawood and Plastic wrap Foil for some Sturdity and lift. Maybe some Helium as well

and how about this!?

Check the mechanism in the first few seconds. Some rotary motors and a real challenge. It reminds me of Dune’s Ornichopter.
