We are planning on testing with larger fan blades and possibly with cut down airplane props.
EDIT: Here's a video of the teste with the airplane props ( the vertical thruster is still using a fan blade in the video) http://youtube.com/watch?v=DeYNCOiSV4Q

Awesome guys! We see that same thing about the plane props. We have used three bladed reverse pitch 12 inch props that we cut down to 4 inches inside a abs coupler as a shroud. The girls team LEGIT is using this idea
