A challenge to the inventional person. A quad-copter and airplane hybrid. It has to land vertically and have four motors that are arranged in a configuration that is in a normal quad-copter frame. I would love to see this in a way for this idea to work. once creating the frame, then make it autonomous so that it can follow a course that includes lots of close quarters maneuvering. try to make this aircraft move as fast as possible. let me know of any takers.
