I've built several from 3dfaomy.com plans.....

Yes they fly (built of fanfold) and they fly well.....and only take a few hours to build....
great for learning 3D because I don't feel bad when a hover at 6" goes bad and the plane breaks in half....I can have another one ready to go that day!

Of course, If I kept my 3D flying higher in the air, they would last longer.....but where is the fun in that?!?!
