An aircraft, such as a radio controlled aircraft, capable of vertical take-off and landing. The aircraft has a compressor in a fuselage that contains an interconnected first and second fans driven by a motor. An intake provides air to the first fan, while a bypass duct directs airflow to the second fan. Air flow from the first fan to the second fan is controlled by a valve, which is operated in tandem with doors in the bypass duct. Nozzles direct air flow out of the compressor in a selected one of a vertical or non-vertical direction for conventional flight or for hover. Hover tubes are provided to adjust the aircraft in pitch, yaw and roll. The hover tubes operate simultaneously with conventional flight controls.
