So i had this idea.. build a Lego mini quad that really flies... So i build one. This build was at first pretty plain and simple.. which you can see in this first video. But it flies well, and even does rolls and flips....( Keep watching the video) But because it is NOT glued... i had to be carefull...
Only the top and bottom plates of the arms are tierapped.

I had it fly prety good, but unfortunatly it broke.. not in a flight, but because i left it on the top of my car, and it felt off on the road.. at 80 km/H
I stoped, drove back.... collected as much as possible, before cars drove over the leftovers... :(

I then re-build this quad, and made it more nice.. and even added Lord Vader.. :) - I love starwars ! :)
Here is the next video of it flying. I did not do any flips and rolls... this build was a bit more heavier.
