A vertical takeoff and landing (VTOL) aircraft design particularly suitable as a full-sized aircraft or remote controlled (RC) model aircraft is disclosed. The invention employs lightweight, high strength materials to reduce the power requirements of the propulsion plant. A preferred system of the invention comprises one internal combustion engine able to spit shaft power to four fan units. The fan units further employ counter rotating fan blades for stability. Separate horizontal and vertical tilting mechanisms delivered to the fan units are additionally disclosed. A variation in design is further included wherein electric motors provide the necessary shaft power.
