Flying Platform, supported by the ducted fan (s), is the safe and simplest airplane. The height of vehicle CG. from the ducted-fan-aerodynamic-center should be selected quite carefully, in the stability and control view point. A simple design philosophy is presented, which makes the horizontal speed and the attitude uncouple. The vehicle is made neutrally stable, and the CG. is located above the ductaerodynamic-center by the order of duct-innerdiameter. This design philosophy would also make the vehicle safe against horizontal gust. Preliminary numerical example is presented by using available (somewhat incOmplete) data. The author believes that this kind of vehicle will attract many youngmen in near future, as their hobby vehicles.
