With all the weird types of planes, copters, or other flying contraptions, I'm surprised they haven't tried a 3D Quad like the Quanum Chaotic 3D Quad. I have been looking into trying a 3D Quad and without many videos or reviews of an 3D Quads out there it's pretty rough. Also watching them try to do some crazy things with 3D FPV would be a blast. Or even a build using the Madcow or other 3D flight controller would be really cool.
