UPDATE: See the BatQuad flying in strong winds http://youtu.be/dm56HjLgamQ This is my first attempt at building a Quad using the Hobbyking KK board. I was lucky enough to get the main parts 3D printed in Plastic from my friends home made RepRap printer. The parts are super strong and super light. All designed in Catia so everything just snaps into position without any stuffing around. Version 2.0 will be even better, I am thinking of printing aero booms with honeycomb reinforcement for extra stiffness.
