My Idea is a cross of a Quad Copter and a Helicopter. Named as a Quad-Hybrid. Good concepts of both of the above mentioned can be used to make a more stable, user friendly and eco friendly device. With more research on this concept, can really the replace the use of Drones (Quadcopters) and Helicopters!
