Ken Gracey, the President of Parallax is building a huge quadcopter. In the picture above it might not look that big but when you realize that the propellers are 14 inches that might put things into perspective! There are 2 X 4 amp hour 18 volt batteries feeding the 770 KV motors. You can see the first flight below, after getting some kinks worked out it seems to fly very well.
